My PC is Frozen: How to Diagnose Faulty Memory - Page 2
In all seriousness, make sure that you discharge any static charge you may have built up by either using an earthing wrist strap or by making sure that the arm you are using to fiddle with the computer is touching the metal chassis of the computer while you do it.
Step 1 - Using the right tools
So what if pushing on the modules doesn't help? Well, a memory diagnostic tool will be required and luckily I have just the tool for you. It is completely free and I use it personally. It is called MemTest86+ and is regularly updated to support new processors. For the purposes of this article I will be using the pre-compiled bootable ISO (.zip) file which should be suitable for 99% of users. Check out the MemTest86+ website to download it.
Unless you have Windows 7 you will also need an application to burn ISO files to CD, I highly recommend ImgBurn.
Step 2 - Booting Up
Once you have your MemTest86+ CD burnt and ready the next step is to put the CD in your drive and reboot your computer. You will need to make sure that your CD Drive is set to boot before your hard drive in the 'BIOS Boot Order' or a lot of computers have the option to select a 'Boot Menu' which you can use when starting.
Step 3 - Running the Diagnostic
After successfully booting from the CD, MemTest86+ will begin a basic scan of your memory modules automatically, any errors are displayed at the bottom of the screen (as pictured left). You may configure more advanced scans by using the 'configuration' menu which is accessed by pressing the 'c' key on your keyboard.
Once you have confirmed the existence of any errors the next part is pin-pointing which module is causing the problem.
Step 4 - Taking Action
If you only have one memory module installed in your computer then the rest of the process is simple, at this point we can assume that the problem exists either with the memory module its self or the slot in which it is installed. To come to a final conclusion all you need to do is turn your computer off, remove the module and slip it into a different DIMM slot and rescan it with MemTest86+.Continued on the next page
