This may be late, but Piledriver CPU's are notorious for crapping out randomly. Honestly, save what you can, sell that 6100 to a friend for fifty bucks, and grab the FX-8350. I have yet to have a problem with mine OC'd to 5.6 GHz, no issues on DayZ with an old 4850 running the system on High. I get around 30-35 FPS on average, with your GPU you should easily surpass me, which in my opinion shows that it's the CPU holding you back. Do you have the same issue on other games?
