Big gph problem

[Kilford9]

I overclocked my xfx r7950 and the temps were to high so i decided to manually reset back to defaults but after applying this all i get is a blue screen after 30 seconds. Need deaperate help as gpu is early bd present

Go into AMD's overclocking utility in Radeon Settings and make sure all the settings are correct.

I would make sure that the clocks are running at stock with a tool like GPUz.

I had a similar issue on my R9 Fury where the clocks actually hadn't reset and It would keep crashing.
Try booting in safe mode and removing the drivers using Display Driver Uninstaller.

Failing that,
Try flipping the BIOS switch on your card while your pc is powered off, then try reboot.
