I realize this is a pretty general problem so please bear with me. I thought this had to do with my RAM so I removed all but one 4GB, ran MEM86 on it and it turned out fine. My computer still reboots randomly. I feel like it might be IO related but I don't know how to test it. My C: is SSD and I have hard drive's connected as well. All internal. EventLog only shows me that the computer unexpectedly shut down but no error code as to why it did so. Any tips on what tools there are to diagnose these things?

How's the heat level? Also, have you recently installed any new drivers, hardware or software? – sgtbeano May 20 '12 at 20:57
temp is fine. it manifests itself quite randomly. more often when the computer is idle than when it's not as well. – chris May 20 '12 at 21:02
If it is a desktop, I would try another psu. – Moab May 20 '12 at 23:05
do 1 thing... start PC...go to BIOS and wait for some time. If it restarts, it clearly is hardware problem.. also try booting Linux live CD and use it for some time to rule out all the hardware/power problems. – tumchaaditya May 23 '12 at 10:44
Are you still having this problem? Because either you self-answer it or we might as well close it for being too localized, because its not helping anyone else – Ivo Flipse Jul 14 '12 at 13:02
