Recently I have run into an annoying problem with Far Cry 3 on my new gaming rig. I was messing with an overclock on my cpu, just testing some things out but when i brought the cpu back to stock, Far Cry 3 wouldn't launch anymore. It will just give me a black screen then give me this error code:

Ive done some research and it is defiantly a hardware error but i couldn't get a definitive answer. Ive gone through my BIOS to check to see if anything looks abnormal but I couldn't find anything. Ive also tried to reinstall and overclock my cpu again but it still didn't help. Everything else on my computer runs fine, even Blood Dragon. Is there something in my BIOS that I might have enabled that I shouldn't?? Can anyone please give me some help??

CPU: AMD FX-6350 3.9 ghz
