Corsair PSU Electrical Buzzing Noise Under Load

Power Supply Coil Whine

This article demonstrates one type of electrical buzzing noise (coil whine)  that computer power supplies can generate under load. In this case, the unwanted noise comes from a Corsair HX100i Platinum PSU – a supposed premium product and chosen for a  silent PC build because of its Zero RPM fan mode and its promised quiet and efficient operation.

Power Supply Units (PSUs) should not sound like this. This one was sent back for an exchange and the replacement was good.


During general desktop use, the power supply was silent.  When required to fulfill demanding power requirements though, the PSU started to make a buzzing sound  like sparks jumping the gap of a Van de Graaff generator and in some instances, like chirping crickets.

It was difficult to determine the power supply as the source of these noises when it was in  situ within the PC case. Noise from cooling fans and spinning hard disk drives can make the noisy culprit difficult to determine by putting your ear inside the computer case. The only way I could make a determination was to remove the power supply from the case and place a demanding load on the PSU. This made it much easier to identify the noise source.

I used the Furmark GPU stress test to make the power demand.

This video demonstrates the electrical buzzing noise from the Corsair HX1000i power supply when put under load and how the noise stops when that demand is removed.

As per Corsair’s recommendations for curing noisy PSUs, all power saving options were disabled on the motherboard and in Windows prior to recording.


  • 02 seconds  : mouse click to start the Furmark GPU stress test. Straight away, the unwanted PSU buzzing noise can be heard.
  • 12 seconds : this is the noise from the GPU fan. However, the electrical noise from the Corsair PSU can still be heard.
  • 24 seconds : mouse click to end the Furmark GPU stress test. The PSU noise and the GPU fan both stop.
  • 29 seconds : the Furmark GPU stress test is repeated and the Corsair power supply noise can heard after the mouse click.
  • 48 seconds : Corsair power supply details shown during the Furmark GPU stress test. Power draw 187W in and 172W out.
  • 59 seconds: Furmark GPU stress test ends and PSU noise stops.

Set Up OpenELEC with TBS Drivers and Tvheadend

How To Set Up OpenELEC with TBS Drivers and Tvheadend

This guide shows you how to upgrade an existing OpenELEC Media Center system with the TBS drivers for Turbosight DVB tuner cards. It then explains how to configure your tuner card to scan for channels so that live TV becomes possible in Kodi by using the tvheadend back end and client add ons.

I have spent an inordinate amount of time testing various OpenELEC images and tailored upgrades and I have finally settled with a system that I now use daily. However, I encountered so many problems in achieving a usable system that I thought it was worthwhile writing down the solutions to help others working on similar projects.

My OpenELEC Media Center:

Dell Studio 540S; 6GB RAM, ASUS 1GB GeForce GT430 and a Turbosight TBS 6280 Dual DVB-T2 tuner card.

Official OpenELEC distro: [Beta] OpenELEC 5.95.1 (x86_64) | Generic 64 bit Build

TBS Driver upgrade image: 6.0 Beta 1 | OpenELEC-Generic.x86_64-6.0.b1-TBS-1.0.tar

Main features: Kodi 15.0 Isengard Beta 1; Video Skip Steps (skip backwards and forwards); remote Power button Suspends and Wakes the machine; serves as a digital video recorder, waking to record and suspending when complete. It’s reliable and boots from cold quickly.

What You Will Need

TBS 6280 Dual DVB-T2 Card Installed

TBS 6280 Dual DVB-T2 Card Installed

  • A Turbosight DVB tuner card installed in your target computer.
  • The computer running the OpenELEC system needs to be connected to your home network, either with a wired ethernet cable or a wireless connection.
  • A second computer, connected to the same network, will be used to connect to the OpenELEC system using the Secure Shell (SSH) network protocol. Linux-based operating systems like Ubuntu and Mint have this tool as standard. If your second computer is running Windows, then download the free telnet and ssh client,  PuTTY to do the same tasks. This computer will also be used to connect to the tvheadend back end with a web browser to allow configuration of the TV server.

The Procedure

  1. Download and then install an official OpenELEC distro on your target system.
  2. Download a compatible upgrade image that contains the TBS DVB drivers. Copy this to your OpenELEC system and upgrade.
  3. Set up tvheadend in Kodi.
  4. Configure tvheadend via the web browser graphical user interface (gui). This includes transmitter selection, scanning for channels and channel mapping.
  5. Instruct Kodi to unload TBS DVB drivers during Suspend. This prevents the loss of tuner functionality when Kodi is woken from sleep.

1. Selection of Official OpenELEC Distros

OpenELEC Download

OpenELEC Download

Visit OpenELEC.tv and navigate to the download page and make your decision on either a 32 or 64 bit operating system.

Nvidia Legacy Builds

Notice the Nvidia Legacy builds that cater for older Nvidia cards. One of my first builds was based on this initial distro because my Nvidia GT430 card was listed as supported. It certainly was, but I found by experimentation that my old GeForce card was also supported in the latest OpenELEC distro too.

My advice then is to try the latest version of the OpenELEC distro. If you find that your card is not supported, then restart your project with one of the Nvidia Legacy builds.  After all, each release is only ~140Mb and the installation time from USB stick, minimal.

My choice: [Beta] OpenELEC 5.95.1 (x86_64) | Generic 64 bit Build

Enter the Update folder and you should find it empty.

Copy the upgrade (.tar) image from your computer to this folder. When the copy process is complete, reboot your OpenELEC system by rebooting Kodi.

When the system reboots, pay attention to the top left of the screen. You should see:

Found new .tar archive. extracting…

The OpenELEC system will reboot automatically when the update has been completed.

Upon reboot, check that your graphics card hardware is still supported after the upgrade. Navigate to:

System > System Info > Video

3. How to Set Up Tvheadend on OpenELEC Media Center

Note: Many problems encountered during the set up and configuration of tvheadend can be resolved easily by a simple reboot of Kodi and your OpenELEC system. Sometimes, the changes you make are not recognized until the next reboot.

3.1 Install the tvheadend backend service

From the Kodi main menu, navigate:

System > Addons > Get Addons (or Install from Repository) > OpenELECMediacenter OS Add-ons > Add-on repository > UnofficialOpenELEC(Generic/x86_64) Add-ons

Install the  UnofficialOpenELEC(Generic/x86_64) Add-on repository.

4.  How to Configure tvheadend

4.1 How to access the tvheadend web configuration page

On your other computer, launch a web browser and type the IP address of your OpenELEC machine into the web browser’s address bar with the port suffix used by tvheadend:-

192.168.x.xxx:9981

This should display the graphical user interface configuration page for tvheadend.

If you are unsure of your OpenELEC system’s IP address, find it in Kodi by navigating to:

System > System Info > Network

Tvheadend Web GUI

Tvheadend Web GUI

If the tvheadend web page fails to show or asks for a user name and password on the first attempt, then on a Linux machine, open up a terminal window by pressing Ctrl + Alt + T (use PuTTY if you have a Windows operating system).

Use a Secure Shell  (SSH) to login as the root on your OpenELEC system. Type:-

ssh root@192.168.x.xxx

The password is:-

openelec

at this point you have access to your OpenELEC system and have  full ability to manage the file system. A list of useful SSH commands can be found here if you need to do something else.

Type:-

tvheadend -C

and press enter. Go back to your web browser and try to access the tvheadend configuration page once more. If this fails, reboot your OpenELEC system and try again.

4.2 Create a tvheadend user account

Configuration > Access Entries > Add

and create a user account with complete access to everything.

Tvheadend Login Account

Tvheadend Login Account

The default account, without a user name or password can then be deleted to secure your system.

Login with your newly created account.

4.3 How to configure tvheadend to scan for channels

On the tvheadend web page, navigate to:

Configuration > DVB Inputs > TV Adapters

tvheadend | Configuration > DVB Inputs > TV adapters

tvheadend | Configuration > DVB Inputs > TV adapters

Check that your tuner card details are displaying the correct driver details. If they do not appear or are incorrect, then search for another update image that may contain the drivers for your card and try again from Step 2.

If all is well, then the first step in this process is to configure the network type.

Networks tab > Add

Networks

tvheadend | Networks

Select the network type from the drop-down list. Either IPTV, ATSC, DVB-S, DVB-C or DVB-T Network.

Give the network a name (“Freeview” in my example) and select the transmitter from which you receive your broadcast. If yours is not represented, try one of the generic ones at the top of the list like Generic auto default.

Tvheadend DVB-T Configuration for Freeview

Tvheadend DVB-T Configuration for Freeview

My example shows a typical DVB-T Freeview set up for the Mendip transmitter in Bristol.

Click Create to complete the network set up.

Now click on the TV adapters tab then the first of your tuners.

Enable the tuner and rename it if you so wish.

At the Networks drop-down menu, select the network that you created in the previous step (“Freeview” in my example).

Select any other options that your tuner supports and when done, click Save.

Repeat this process if you have more than one tuner.

Tvheadend TBS Tuner Configuration

Tvheadend TBS Tuner Configuration

Now, go back to the Networks tab and wait for the #Services (channels) to be found. There is no requirement to press any sort of scan button. As soon as the network and tuners are configured, tvheadend will begin to scan for channels.

Tvheadend can take a few minutes to complete the scan. Initially, #Muxes will be equal to Scan Q Length.

Tvheadend Start of Channel Scan | #Muxes = Scan Q Length

Tvheadend Start of Channel Scan | #Muxes = Scan Q Length

As each of the pre-defined muxes are scanned, Scan Q Length will decrease accordingly. The channel scan will have finished when Scan Q Length reaches zero.

Tvheadend Channel Scan Progressing | Scan Q Length Total Decreasing and #Services Increasing

Tvheadend Channel Scan Progressing | Scan Q Length Total Decreasing and #Services Increasing

Tvheadend Channel Scan Successful

Tvheadend Channel Scan Successful

If, at the end of the scan, no channels have been found, then edit your network profile and change Pre-defined Muxes to Generic-auto-default and try again. Press Force Scan to initiate this.

4.4 Map services in tvheadend

When tvheadend has completed a successful scan and has returned a good number of services, the next step is to map those services to channels.

Configuration > DVB Inputs > Services > Map All

tvheadend | Map all (Services to Channels)

tvheadend | Map All (Services to Channels)

Make the following selections and then click the Map  button to map services to tv channels.

tvheadend | Map All Selections

tvheadend | Map Services

  • Check availability – if you select this option, services that are not currently transmitting will be omitted.
  • Include encrypted services – self explanatory.
  • Merge same name – prevents channel name duplication.
  • Create provider tags – produces useful tags that Kodi can use to filter tv channels; for example, SDTV and HDTV. It’s beneficial to select this option.

The mapping process should be completed quickly in a matter of seconds. And when complete, TV will appear in the Kodi menu.

5. How to unload OpenELEC DVB drivers for suspend

Depending on your tuner card and the TBS drivers chosen, a condition may exist where the tuner card(s) cannot be accessed after the computer has been suspended and then woken. This problem spoils the whole installation and means that the system cannot be used reliably as a digital video recorder.

To circumvent this problem it is necessary to force the DVB driver modules to unload during the Suspend operation.

Reboot your OpenELEC system and ensure that you are able to play TV channels to demonstrate that the tuner drivers are loaded and running.

Use a Secure Shell (SSH) to log into your OpenELEC system as described in step 4.1, and having logged in as root, type:-

lsmod

and press Enter. This command will list and detail the kernel modules that are currently loaded.

lsmod | OpenELEC

lsmod | OpenELEC

Look down the list and take note of the module name that is clearly associated with your tuner. In this case, the module name is:-

saa716x_tbs_dvb

Go to your OpenELEC system and using Kodi, navigate to the tvheadend back end service add on. Click configure and choose the DVB tab.

Settings - Tvheadend | DVB

Add the module name to the field entitled Unload DVB modules before suspend and click OK.

A notice that Kodi is Working and unloading the DVB drivers will be seen when Suspend is now initiated. The drivers will be re-loaded upon resume.

6. Other Aspects to Try

Once you have your OpenELEC machine running reliably, you may want to consider exploring the following to improve your system.

  • Tvheadend – Timeshifting with available RAM.
  • Configuring Kodi Power Management to Suspend your machine after so many minutes of inactivity.
  • Recording time offsets so that you don’t miss the beginning or end of your favourite shows.
  • Adding TV logos to your TV channels.

Lightroom in Ubuntu

Lightroom in Ubuntu

This guide shows how Adobe Lightroom can be run in Ubuntu through a virtual machine, courtesy of Oracle’s VirtualBox.

This video illustrates the functionality and responsiveness of Adobe Lightroom 6 running on the following hardware, native operating system and virtual machine:-

  • Dell XPS420 – Intel® Core™2 Quad CPU Q6600 @ 2.40GHz × 4  and 4GB RAM.
  • Host Operating System: Ubuntu 14.04LTS (64 bit)
  • Guest Virtual Machine: Windows 7 (64 bit) Home Premium.

The video also illustrates the seamless integration of Windows 7 with the Ubuntu desktop environment, allowing both Linux and Windows programs to be run side-by-side.

In today’s terms, the Dell XPS420 is an old desktop machine. Newer PCs, with faster processors and more RAM are likely to perform much better than shown. But it is worth noting that I have had success in getting Lightroom to run adequately on an even older Acer Aspire laptop with a slower dual core processor and less RAM.

Video Details:

  1. Browsing a webpage with Mozilla Firefox in Ubuntu. Re-sizing the browser and moving it around the Ubuntu desktop. Browser then minimized.
  2. Clicked Start on the VirtualBox Manager to launch the virtual machine installed with Windows 7 (64 bit) Home Premium.
  3. Typing password to logon to Windows 7.
  4. Windows START > Calculator and then maximize Mozilla Firefox from Ubuntu.
  5. Windows START > Adobe Lightroom.
  6. Showing the speed of Adobe Lightroom 6 Library by double-clicking a few images to maximize them.
  7. Folder removal then imported back to demonstrate the import speed: 20 x RAW NEF image files totalling 380MB.
  8. Chosing a RAW image to develop.
  9. Zooming in 1:1 then spot removal tool use to conceal sensor dirt.
  10. Image to black and white and various adjustments made.
  11. Zooming in 1:1 and out a couple of times to look at detail.
  12. Pressing F on keyboard to view adjusted image in full screen.
  13. Exporting image: 18MB NEF file exported to 795KB 1060 x 1600 jpg (95% reduction).
  14. Exported image then displayed with Windows Photo Viewer.
  15. Back to the Ubuntu Firefox browser to demonstrate that it is still responsive.
  16. Closing down Lightroom.
  17. Shutting down Windows 7 to return the Ubuntu desktop.

Getting Lightroom to Run in Ubuntu

Check the specification of your PC. It needs to outperform the minimum requirements of your Ubuntu operating system AND the version of Adobe Lightroom you wish to use.

Minimum System Requirements: Ubuntu | Adobe Lightroom 6

Take note of the operating systems that are capable of running your version of Adobe Lightroom and make sure you have an appropriate installation CD/DVD and licence key to hand.

Please follow my guide on How To Install VirtualBox in Ubuntu. It describes how to install Oracle’s VirtualBox; make a virtual machine and install the Windows 7 (64 bit) Home Premium operating system; how  to install Windows Guest Additions CD Image and how to integrate the two environments of Ubuntu and Windows 7 seamlessly to make one unified desktop. The article shows you how to share files and folders between the two operating system and install Windows software.

Once you have Adobe Lightroom installed on your virtual machine it is time to tweak the settings of that virtual machine to make it snappy. These tweaks made Lightroom more responsive for my hardware.

Base Memory: As much as you can afford. 2GB is the minimum requirement for Adobe Lightroom. Leave at least 2GB for Ubuntu.

Processors: From a Quad Core Processor I dedicated 3 of those cores to the Windows 7 operating system.

Execution Cap: Reduced from 100% to 90%. This prevented Windows 7 from stalling programs in Ubuntu.

Video Memory: From a 256MB GeForce Graphics Card, half of that memory given to Windows 7.

Acceleration: 2D & 3D switched on. Made little difference. Lightroom reported that it could not find a GPU to assist in processing.

3.4 Work through the installation process by clicking Next and Install if asked for permission to install device software. Re-boot the guest operating system when prompted to do so.

4. How To Integrate Windows 7 and Ubuntu Desktops

4.1 When the guest operating system re-boots, you should notice that resizing the VirtualBox window also resizes the Windows desktop too. This demonstrates that the Windows Guest Additions are working properly.

4.2 To integrate the guest environment with the host operating system (i.e. integrate Windows 7 with Ubuntu, seamlessly), hover your mouse over the top menu bar to reveal the VirtualBox menu and select View > Switch to seamless mode. To switch back, move your mouse to the bottom centre of the screen to access the guest operating system menu.

Alternatively, you can use the quick-key combination of host-key + L to enable and disable seamless mode. The host-key default is the right control key. Right Ctrl + L.

Seamless integration means that the Windows task bar is accessible at the bottom of the Ubuntu desktop and both Linux and Windows programs can be run side by side.

 5. How To Share Files and Folders with VirtualBox

5.1 The installation of Windows Guest Additions should allow drag and drop functionality between the host and guest operating systems, either one way or bidirectionally. By default, this function is disabled. In the VirtualBox menu, select Devices > Drag’n’Drop > and your direction preference.

5.2 The clipboard can also be shared between host and guest operating systems in a similar manner. Select Devices > Shared Clipboard > and your direction preference.

5.3 Devices > Shared Folders Settings… allows the sharing of host folders with the guest operating system in order that files can be shared between them.

VirtualBox | Shared Folders

6. How To Install Software on the Virtual Machine

To install software on your guest operating system you have a number of options:-

  • Use the browser of the guest operating system to download the software and install it from the appropriate download folder.
  • Make an ISO file of the installation CD/DVD and have that available in a shared folder on the host operating system as described in step 5.3.
  • Make an ISO file of the installation CD/DVD and mount that in the same manner as described in step 2.12.
  • Enable Drag’n’Drop and move files accordingly.
  • Use the Shared Clipboard to Copy files from the host to the guest operating system.

Once your virtual machine is running with folder shares, it is quite easy to start testing various types of software.

See Adobe Lightroom 6 working in Ubuntu.

To get Adobe Lightroom installed I shared two folders with the virtual machine; one that contained the installation files and a second that contained my photographs. I installed Lightroom from the Network Share described in step 5.4.

Photographs were imported into Lightroom’s Library by adding the second Network Share to Folders.

Kodi Not Scraping

Kodi Not Scraping

If the System Attribute flag is set on a Windows folder containing a movie, TV shows or music, then Kodi (XBMC) and Mediaportal will fail to register that these folders even exist during a scrape. This means that media inside them will not show in the integrated file managers and will be missing from the relevant media libraries. These folders are simply ignored during scrapes.

This problem seems to be specific to the Windows operating system. Scraping the same media from a Linux-based Kodi installation will work perfectly.

My Specific Problem

I have three media centres around the house, all being fed by a Synology Network Attached Storage (NAS) that stores all my media files. Two machines have Kodi installations on Linux operating systems. The main machine has a Kodi and Mediaportal installation on Windows 7 64-bit. On this machine, access to the NAS media is obtained by a network mounted drive under a local drive letter, “Y:”. That drive source has been added to Kodi and Mediaportal.

Initially, the addition of new media to the NAS caused no problems until I began to use a computer running Ubuntu to rename media files before moving those files to the appropriate folders on the network attached drive.

FileBot, the file renaming tool for Linux-based operating systems, seemed to be causing the problem by generating the Windows System attribute on renamed folders.

Although the two Kodi installations on Linux were able to scrape this new media successfully, the Windows installations of Kodi and Mediaportal were unsuccessful. The video files were missing from media libraries and could not be seen in the file managers. Windows explorer however, showed the folders and their contained files. The folders were there in the directory listing but were being ignored during the scraping process.

Solution

1) Go through the steps outlined in  the Kodi wiki for Incorrect and Missing Videos.

2) Determine if the System Attribute flag is on for missing videos:

By default, folder and file attributes are not displayed in Windows Explorer, but they can be enabled quite easily. Navigate to your media library. Right click on the column header and select Attributes. If Attributes is not visible, click on More… and select it from the list.

File Attributes Enabled in Windows Explorer

File Attributes Enabled in Windows Explorer

Look down your list of folders while paying attention to the attributes column on the right. Identify the folders that have the System attribute switched on. This will be denoted with an “S”.

The basic attributes list:

  • R – Read Only
  • H – Hidden
  • A – Archived
  • S – System
  • D – Directory

3) Deselect the System Attribute flag on folders:

There are two ways to remove the System Attribute flag on a folder.

i) The first way is to use the DOS command attrib in an elevated cmd window to change file and folder attributes. Due to the complexity and length of some of my file paths, I opted not to use this and use the next option instead.

ii) Download Attribute Changer, a very useful tool to do the work with just a few simple clicks.

Once installed, a simple right click on a folder or file displays the option to Change Attributes…

Selecting this option and then the Folder Properties tab shows the available attributes that can be removed or added.

Remove the folder’s System Attribute flag by unticking System in the Folder Properties tab. Click OK.

Refresh the directory listing to ensure that the flag has been removed.

Launch Kodi or Mediaportal to update your media library.

How To Block Text Message SMS Spam

How To Block Text Message SMS SPAM on Samsung Galaxy Phones (Android)

If you’ve started receiving SPAM SMS text messages purporting to be from LloydsBank, Sky or elsewhere, and you cannot report them as SPAM because of the invalid number error, there is a workaround to divert these messages to your existing SMS SPAM box without installing SPAM-catching applications.

I will show you how, using the LloydsBank SPAM SMS text message that has been plaguing me for a while.

LloydsBank SMS SPAM Text Message

The LloydsBank SPAM SMS text message appears something like this in your SMS Inbox.

If you Press and Hold the text message to bring up the options associated with it, you have the option to Delete the thread or Register as spam number.

Android Text Message SMS SPAM | Register as spam number

Register as spam number

Registering text messages as SPAM usually works to divert subsequent messages to your SPAM folder. Unfortunately though, spammers have become crafty and use alphanumeric strings or numbers that are too long to be recognized as telephone numbers in their transmissions. This results in the invalid number error when trying to register a number as SPAM. This means that marking that text as SPAM fails and you will continue to receive them in your SMS inbox.

How To Block Text Message SMS SPAM with Invalid Number Error

Open up a thread of the offending SPAM messages to identify a recurring keyword. In the example of the LloydsBank SPAM SMS, there are a few, namely;

  • A/C
  • Bal
  • CR
  • DR
  • Entries

SPAM Keywords and Phrases to Block

To block the LloydsBank SPAM SMS text message, I have used the word entries, but I could have used any of the others identified earlier.

It is important to note that:

  • phrase and word matches are not case sensitive
  • a genuine SMS text message could be diverted to your SPAM folder if it contains one of your entered words or phrases. So choose wisely.

Once you have set-up phrase blocking, it is worth checking your SPAM SMS folder occasionally to check it’s effectiveness. It can be accessed from your SMS text message Inbox screen and by pressing your device’s Menu button, then selecting SPAM messages.

Speed Up DNS Propagation

Speed Up DNS Propagation by Ensuring DNS Cache is Purged

DNS Propagation Taking Too Long | DNS Replication Problems | How To Clear DNS Cache | DNS Troubleshooting | DNS Benchmarking | Changing DNS Provider

Modified DNS entries can take hours or even days to replicate across the internet. And often, this delay can be extended unnecessarily by old DNS cache residing on your computer and slow, Public DNS servers.

This article details the checks you should perform after updating DNS records to ensure that cached DNS lists and slow-to-refresh Public DNS  servers are not misdirecting your browser and causing unwanted delays.

This article is useful in these circumstances:-

  1. Moving a web site from one host to another: When name servers or DNS records have been updated to point your domain to a new hosting company. The hosting company confirms that the DNS transfer is complete and that your site is working normally but your domain name still directs to your previous host and old website.
  2. Pointing a domain name to a website: When name servers and DNS records have been set to point your new domain name to your new web site. You are still waiting for DNS records to propagate throughout the world’s networks for your new web site domain name to be resolved.
  3. Troubleshooting a problem with DNS.
  4. Learning how to clear your DNS cache.
  5. Making browsing speed faster. You could benefit by changing your ISP’s default DNS servers.
  6. Benchmarking DNS servers in order to choose the one optimal for you.

What is DNS?

The Domain Name System (or Service or Server) is a look-up table that resolves internet web addresses like Facebook to their respective IP address, i.e. 173.252.110.27 – the backbone on which computers are able to connect and communicate.

Without a DNS directory, we would all have to remember meaningless numbers instead of easy-to-remember names.

When a web address is requested in a browser, it’s equivalent IP address is sought by these steps and in this order.

1. Local hosts File

On a Windows Operating System, the hosts file in:

c:\windows\system32\drivers\etc\

is the first port of call. If the web address is recorded in that file with a corresponding IP address, then the browser will be directed and the search ends there.

2. Locally Cached DNS

If there is no record of that web address in the hosts file, then locally cached DNS is searched next. This can be stored on the computer itself and / or inside the router. If a suitable record exists in stored DNS cache, the search will conclude there and the browser will be  directed to that stored IP address.

Some routers are capable of storing a cached copy of Domain Name System lists. If one does exist, this cache will be the next list to be searched to enable fast interpretation of the web address, instead of requesting that data from a Public DNS.

3. Public DNS

Only when the previous two steps cannot be fulfilled does the request go to a Public DNS to resolve the web address to an IP address.

How Web Addresses are Resolved with a Domain Name System

How a Web Address is Resolved to an IP Address with DNS

 

How to Clear Cached DNS

Follow these steps to ensure that you are not waiting unnecessarily for DNS replication and propagation after updating DNS records and name servers of your website.

Check the hosts file

It is always worth checking your hosts file in notepad to see if there have been any redirects added in the past that you may have forgotten about – or indeed, not known about.

Tip! notepad has to be opened with Administrative privileges if you are going to make any changes to your hosts file.

If there is a reference in your hosts file to your problematic site, then  make a back up of the file; remove that entry and save the hosts file. You may need to re-boot your computer for the new hosts file to be read by the operating system.

Clear Local DNS Cache

Open a command console with Administrative privileges by clicking on the Windows START icon (bottom left) and typing cmd into the search field. Do not press Enter.

cmd.exe will appear at the top of the list. Right click on it and select Run as administrator. The command console will open.

In the command console type:

ipconfig /flushdns

and press Enter.

Windows Command Console: Ipconfig /flushdns

ipconfig /flushdns

The console will report Successfully flushed the DNS Resolver Cache. Close the console window.

Check and Clear Router DNS Cache

Some routers are capable of caching DNS lists. You should determine whether or not your router does this and if it does, purge that list.

Log into your router and look for for an option or something that resembles Advanced DHCP Settings or DNS Settings.

The example shown below is of a NetGear router with the option to clear router DNS cache.

Clear Cache DNS NetGear Router

NetGear Router Configuration: Advanced DHCP Settings – Purge DNS Server List

Change the Public DNS Primary and Secondary Addresses in your Router

By default, most routers are programmed to obtain and use your ISP’s Primary and Secondary DNS addresses automatically.

However, these servers could be slow to replicate changes in DNS records and therefore slow to propagate the changes you have made. They might be over loaded too, causing substantial look-up delays that decrease browsing speed.

There are many alternatives to DNS servers supplied by ISPs. The benefits of using an alternate provider include:-

  • Faster refreshing of DNS record changes
  • Faster browsing speeds
  • Improved security
  • Family filtering

Google Public DNS is a free Domain Name System that can be easily configured for use in your router without having to install any software. OpenDNS is another free Domain Name System that is commonly used.

To configure your router manually to use another Public DNS, log in to it and find an option similar to this: Domain Name Server (DNS) Address and select Use These DNS Servers. Enter the two IP addresses given by your chosen provider.

OpenDNS Router Configuration

Save the changes if necessary then re-boot the router.

Once all these steps have been completed, try to access your domain again.
