That sure is a title!
Hey guys, I built my own pc some weeks back, seems to be working fine. Today I decided to overclock my 3570k. I am at 4.2 with -.05 (might be missing a 0 there). I ran prime for 45 mins, my voltage was like 1.08 (insert measuring unit) and my cores were at 66 Celsius. I was happy and went to my bios. I saved the settings, loaded defaults and proceeded. But when windows was loading, my computer crashed! I made sure it was on default. I'm really scared to turn my pc back on, what do I do?
