Oldie but was a goodie till I got greedy

So I have a xfx 6850 and a i3 530@stable 4.2 GHz daily CPU not the issue I dug this old system old the shed litterly out the shed as well I may add , any way CPU running fine n dandy till I started OC'ing the GPU via afterburner bumped the core clock up a bit too much and fan speed at 100% now every time I boot the system i can get into the bios breifly then complete black screen , managed to get the bios bk to stock so ram and CPU etc are all stock speeds but every time I fire up the machine it starts to load windows GPU fan comes on 100% and bam black screen GPU just seems to stop working is there a way to reverse the GPU overclock somehow ?

Any luck booting into safe mode?

 

Maybe take the GPU out and see if it will boot? That way you can confirm its a GPU issue?

Hit f8 during boot and load into safe mode and uninstall afterburner and rivatuner.  start hitting f8 after the bios loads but before windows starts to load.  if you cant get f8 to work you need to disable fast boot in the bios.

I don't have onboard graphics on with mobo and I don't have another graphics card to hand at the moment to test with

So it will boot into safe mode for all of maybe 20-30 sec's and then complete black screen GPU fan ramps up to 100% and and to hard reset . . . Think I've fried the GPU

Oh, my bad sorry.

 

Sounds like booting into safe mode is by far the best action at the moment. If that goes nowhere then time for a new course of action.

Yeh , no it's just locking up and black screen / GPU fan ramp up , it's like afterburner has altered the GPU bios , how would I access that to be able to bring it bk down again

Could I load Ubuntu onto it and change the GPU bios that way then boot bk into windows

Is reinstalling windows completely out of the picture? 

 

Maybe disconnect your drive and attempt starting the process of a reinstall to see if it will even post into a windows install.

Well I had it booted and had it sat in the bios of the system and it still done it . . . twice in a row . . . Think I've fried it , like well and truly fried that poor old little GPU oh well on to bigger and better things I guese
