Hello guys, I have an asrock 970 extreme3 and fx 8320 , Everything was working fine till I decided to oc the cpu to 4.2ghz(1.3750v) I oc'ed it and the os booted fine , I didn't do any stability test instead I junped right away to the mobomanufacturers's site to download and update the bios , I run a the default gui tool supplied by the manufacturer and it showed a progress bar ( I didn't select any thing nor I chose the bios file , just started the exe) in themiddle of the loading pc frozen and I heared very weird sound , similar to electric shock. I turned it of by un-plugging the power cable . I turned it on again but the monitor didn't display anything, fans spin and everything seems to be fine except there was no display at all. I tried another rams but nothing changed . I tried another GPU but to no avail . I tried another psu and nothing. I tried to run my cpu on my spare motherbt and it worked fine. At this point I can't figure out what to do please share your knowledge.
