In your case this is good because you weren't stable so starting from scratch is probably the best thing to do. I noticed you have a 2600k, what clock were you trying to achieve at what VCC voltage? (core voltage).

4.5 required 1.375v for me (so far). It's less for some people and even more for others. Every chip is different.
I would be happy if I can go up to 4.5. I had it set at 4.00. I don't remember exctly what the VCC was. I want a VERY stable system 24/7 rather than a fast and furious My workflow requires the machine to be up 24/7 as I plan to do rendering at night.

Hmm, try 1.3v for 4.0. Run P95 for at least 12 hours. If it passes you can lower the voltage if you want to achieve even better temperatures. However, 1.30v seems to be the sweet spot for most chips at 4.0.

Your PC shut off because it was an unstable overclock, and sometimes it cannot boot afterwards. Clearing the CMOS fixes it.
I am just curious. How would a BIOS setting correct a corrupt file? Or is it that depending on the BIOS setting a file is being read differently? Hmm, can't wait to give it try when I go home tonight

i had the same problem you had, minus the corrupt os. i was overclocking and running test, all of a sudden the pc just shutdown. after doing some quick investigating, i determined my psu was hot and triggered the shutdown feature. i replaced the psu, problem fixed. im not saying this is your problem, just giving you possible problems.

Sometimes after an unstable overclock the PC will not boot. It's not unusual. Resetting the CMOS only restores everything back to default clock values. If the unstable overclock caused the OS to become corrupt, then you'll have to do a reinstall or try a repair first.

No luck!! I have reset the CMOS. It is the same result. I am trying to install on the SATA Drive now and see if I can access the previous system drive.

Sounds like one of three things happened:
1) RAM died (unstable RAM can corrupt the OS on boot or install)
2) bad power supply.
3) installation of bad software or malware.

The fact that the system *powered off* instead of just rebooting from a BSOD, suggests a power supply or a motherboard voltage fault.

When you said it shut off, did it come back on after 5 seconds? Or did it remain turned off? It it turned off and did not automatically come back on, that's PSU related.

I am ruling our #1 and #3. It could be #2. I have a 750W power supply, but the video card (GTX 560 Ti) alone is pulling 500W. So I will be running Prime95 again and if that happens again, I will move up to 850W.
