information   Information
This will show you how to run the Windows Memory Diagnostic Tool to test the Random Access Memory (RAM) on your computer for errors in Windows 7. The diagnostic includes a comprehensive set of memory tests. If you are experiencing problems while running Windows, you can use the diagnostic to determine whether the problems are caused by failing hardware, such as RAM or the memory system of your motherboard.

If you suspect memory issues, then you may also want to consider using and running Memtest86+ at boot. Memtest86+ is a comprehensive stand-alone memory diagnostic program that you boot from at startup to test your RAM. You can download a ISO file to burn to DVD to boot with, or a floppy disk package installable from Windows to a USB flash drive or floppy disk to boot with.
