So I've been having BSOD problems for the last two years or so, and not been able to track down the problem. Among other things, I ran MemTest86 a half-dozen times for as many as 48 hours, and it never revealed a single fault. I recently upgraded my mobo and RAM, and started experiencing the same problems again. Naturally, I assume it's the same bad driver, that I just can't find.
However, being the circumspect troubleshooter I am, I admitted to myself that this new RAM might actually be bad. I decided to run MemTest86 and Windows Memory Diagnostic again. This time, WMD showed a fault of some kind.
Having never discovered what the other problem might have been, I'm reticent to blame all my troubles on this one fault.
The only hardware I haven't replaced or completely ruled out are the Power Supply and the CPU. So, my question is is it possible for something other than a bad module to create a fault in WMD and/or MemTest86? Could the power supply be doing something weird that would make the RAM seem bad when it really isn't? Could the CPU have a non-critical fault that occasionally corrupts memory, but doesn't cause any other problems?
How much should I trust the memory diagnostic?
