So I've had my gaming rig for about 2 years now, and she has ran perfectly up until about a week ago. It will now randomly crash and reboot, without any error messages or anything, pretty much like the power just goes out. Over the course of the last 3 days, it probably has crashed about 4-6 a day.
There doesn't seem to be any reason for it, as sometimes it crashes within a couple of minutes of loading Windows and other times I have been able to play Battlefield BC2 for several hours before crashing.
I've ruled out that it isn't an overheating issue and I have ran memtest86+ successfully and don't believe it to be the cause either. I'm wondering if this could be an issue with my power supply, but wouldn't this mean it would crash more often when playing games and running other hardware intensive programs?
