Part of the service is the Windows Memory Diagnostic software which is a standalone tool that can scan the computer memory and report on errors it found.

Windows Memory Diagnostic (link, via Vishal) is a dos tool which has to be installed on a floppy drive or CD. It can only be run during system start and not from within Windows. Many users will feel uncomfortable with this procedure but those affected by crashes might probably be inclined to try everything in their might to get to the reason of the crashes.

The tool will start the computer memory check instantly after its interface has been loaded during system startup. It will run test passes and it is important to perform at least one full test pass before quitting the software program.

The first test pass is the most important one. If no errors are found it is unlikely that additional runs will find errors. If errors are found you discovered a possible source for the system crashes, bluescreens and stop errors.

The installation should not pose difficulties for anyone. Buttons to create a startup floppy disk and to save a CD image to disk are provided upon execution. The first will create a bootable floppy disk containing the Windows Memory Diagnostic tool while the latter will create in ISO image windiag.iso that has to be burned to CD or DVD.

An alternative to Windows Memory Diagnostic is Memtest86+ which is highly recommended by computer professionals to check ram of computers. It has also be burned to CD and run during system start.

Faulty memory is one of the main reasons for instability. The first task should be to make sure that the memory is correctly inserted into the memory banks. Make sure you count the number of bars and check if you are running dual channel mode or not.

Download the free software Memtest86+ as an iso image (currently Memtest 3.3 iso) and burn it to a compact disk. Reboot your computer afterwards and boot the CD that you just created. You might need to change the boot order in your bios to be able to boot from CD. Memtest86+ is starting automatically from CD and performing in depth memory tests that could take hours to complete.

If errors are encountered during the test you know that you have faulty RAM and need to replace it. If you have more than one RAM bar installed you should test them separately to make sure you know which one is the faulty one. I ran the test just a few hours ago and realized that one of my ram bars is indeed faulty which made me order new RAM immediately.
