I have my E2160 set at 2.8ghz, and I have a P35-DS3L. I had been running Prime95 on Small FFT for a little above 7.5 hours, and I stepped away from my computer. When I came back, I noticed that the computer had been reset. I check the bios, and all the settings are still on the OC, so the bios did not reset. What does this mean?
