Picked this one up from Sergar in the Searchwinsystems newsletter. Microsoft has released a Online crash analyzer utility for RAM. It is a standalone self booting module you put on a disk or CD and boot to, to test your memory on your PC. http://oca.microsoft.com/en/windiag.asp The Windows Memory Diagnostic tests the Random Access Memory (RAM) on your computer for errors. 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. Windows Memory Diagnostic is designed to be easy and fast. On most configurations, you can download the diagnostic, read the documentation, run the test and complete the first test pass in less than 30 minutes.
