Failed gtx570 overclock

[QuestioningGuy]

So this is how it happened:

I was reading some posts about what overclocked clock speeds are on gtx570. I turned up the voltage to 1100mv, core 860mhz, memory 2100mhz. I ran a benchmark (MSI furry donut v2) to see what fps I was getting for that oc. First I ran it at stock speeds. Then I ran it at that with overclock. It passed about 40% and crashed. Crashes are normal for me because I am not a good overclocker. But the pc turned off instead of restarting. It didn't turn on anymore with that gpu installed, and when I took the gpu out, it took solid 30 seconds spaming power switch to turn on the pc. Also, the pc posts with gpu installed and no power cables running to it, 8pin pluged in. When I plug all the necessary power, or only the 6 pin, pc doesn't post. Please tell me if there is something I can do.

Use the iGPU to uninstall drivers and reinstall the graphics card after that. Also, use something like unigine valley instead of furmark because unigine valley represents a more realistic gaming load.

I don't have either another gpu or onboard graphics

borrow one or buy an upgrade

I uninstalled everything associated to gpu. Same thing. P.s. when I press the power button all system and gpu fans spin for about quarter of a second. That is what was going on
