use the onboard and boot into windows with safe mode

uninstall the software you used to overclock, probably also a good idea to uninstall gpu drivers


install the card back, and hopefully you should be able to boot with it

OK, the important thing i forgot. I used ATiWINFLASH to flash a hd 6970 bios and heres the link :https://forums.overclockers.co.uk/threads/unlock-your-ati-6950-to-a-6970-thread.18221844/
I followed him and before i did this , i change the vga output something that was set to 560 mhz i changed it to 1000 mhz and flashed a new rom
after i flashed it i rebooted it and there was no display cpu was running fnas were spinning but nothing

bricked the card then


place the gpu in a secondary pcie slot, boot into windows with the onboard

then flash it back to stock bios
