Troubleshooting Random Reboots
I'm having issues with my PC randomly rebooting. I've tested the memory using memtest86+ overnight and everything was fine. I can also run benchmarks such as Orthos or Prime95 for long periods of time without crashes. My system is not overclocked.
Thinking maybe my windows installation was fubar'ed (I had changed graphics cards from Nvidia to ATI), I rebuilt my system. Now, in addition to the reboots, my monitor will not power off. The display goes blank whenever it's told to go off, but it never enters power saving mode.
I've disabled automatic restarting, and have never seen a blue screen, it just boots without displaying anything. I'm at my wits end and have no idea how to troubleshoot from here on out...
My thinking is either power supply or motherboard at this point...
Any ideas?
