Executive summary: on normal use my GPU is *always* at 0% activity and when doing anything graphics related (run a game/benchmark, update drivers) my PC hard reboots. Using lastest drivers on Windows 8 Pro x64. I've already tried switching between beta and stable drivers while on Windows Safe mode and even reinstalling the OS.
Specs:
CPU - AMD FX 8320
Mobo - Asus M5A97 R2.0
Graphics - Sapphire HD 6870 1GB
RAM - Adata XPG 2.0 1600MHz 2x4GB
HDD - Hitachi 7200rpm 500GB
PSU - Thermaltake TR2 500W
Hi, first time poster here c: I'm having a hard time working this out. Right now I'm thinking it's a hardware failure (either PSU or graphics card), but I'm not really sure so here's the situation:
A couple weeks ago I had my rig running fine. Played FC Blood Dragon, Metro LL on (close to) highest settings. Then I was forced to reinstall Windows 8 (unrelated) and problems began. I installed the lastest stable drivers/CCC and I repeatedly got BSOD with SYSTEM_SERVICE_EXCEPTION and UNHANDLED_THREAD_EXCEPTION on atikmdag.sys. Had a couple more problems, but installing all Windows updates and the AMD beta drivers (only drivers, no CCC) seemed to work. With that I was able to run games and I even tried bitcoin mining for a while (5 hours top, nothing too extreme). Then my current problem showed up. Now I can't even watch an HD vid and sometimes I also get some screen tearing during normal use.
Might be worth mentioning that the lights went out during a storm recently, although as the computer is plugged to a UPS, it did shutdown normally.
I'd really apreciate your help or any tips you could give me. Thanks!
