I think I may have cooked my i5-2500K after 3 years of overclocking. Even at stock clocks, I get periodic reboots and under a Prime95 load, the machine just spontaneously goes back to POST after less than 10 minutes.
Microcenter recommended a new CPU/MB, though I was suspecting a PSU issue. In the brief time I was able to view my rails during Prime95 I didn't see anything more than 2-3% out of spec.
I went AMD instead of Intel this time and picked up an 8320 and an open box Crossfire V Formula Z (who thinks up these names?) I also picked up a Hyper 212 EVO cooler. I get everything hooked up, load the OS, and then decide to run a check on my SnapRAID array before I go to bed. It starts running and I nod off.
When I wake up, the system is black with no response from the keyboard to wake it. The power button on the case is not even responsive when held down for 5 seconds! I turn it off from the PSU switch and turn it back on from the front (button works now.) It powers up but does not POST. Again the PSU button does not work to turn it off.
I shut if off again from the PSU and let it sit for a few minutes. I power it back on and it POSTs and goes into Windows. It black screens again in less than a minute. I shut it off again at the PSU. Power on again after a few minutes and attempt to run HiRen's boot disk to run MemTest. Before I can get to the application it black screens again.
Reboot again and check BIOS for temps. All is well with temps in the low 30s.
Not sure if it's my open box MB or the PSU at this point. I'm thinking PSU now, but it's just another hunch.
