Memory Question

[travisflyer]

I have a custom built P-4 with 1 gig of PC-3200 memory. The problem I'm having is that during games the system will crash for no reason or it will just reboot for no reason. Is their any way to test the memory to see if its the culprit. I've changed out just about every thing else but not the memory. Any help would be appreciated

Make sure the fans are all still working, i would think something is overheating, since it only happens during heavy load.
