Help! PC keeps crashing.....

[psychomania18]

Hi everyone, so i have had my custom gaming pc for about 2 years now with no problems. Today i was messing around with some stuff and when i was trying to overclock my graphics card instead of overclocking the memory speed(which i was trying to do) i accidentally overclocked the core speed really high and all my 3 screens went crazy colors and had tearing everywhere. So i immediately shut my PC down and rebooted it. After that everything seemed fine until i ran any thing involving graphics i.e. twitch, YouTube , Netflix, and games too. Once i did that my PC would completely freeze and i cant do anything except shut down completely by holding power button down. But if i go into MSI AfterBurner and run stress test my PC doesn't crash oddly.  i reinstalled graphics drivers and didnt help. I am worried i completely ruined my gpu and i dont know what to do. PLEASE HELP!!!!!!!

 

system specs: gpu: gtx 770 4gb

motherboard: asus m5a97 R2.0

HDD: 1T

750w psu

Try backing up your current image and use a blank Windows.

you mean like reinstall windows?

is there a bios switch on the gpu?

 

could have fried your card. don't understand why you would try to over clock something that probably didn't need to be.

no there is no bios switch on the card. i was just messing around and see if i get some extra performance on games.....

You may have screwed up the GPU. Did you uninstall the graphics drivers and install them again? Not just install over them, but remove the drivers entirely.
