recently built my 1st pc, got a gtx970 to go with. abit of hiccups here and there, like my ram doesnt work with dual channel set up, only a single 8gb stick works, hdd wont initialize and stuff like that. but generally its working well.I dunno, all that stuff is highly abnormal and probably indicates a hardware fault somewhere. If you built it yourself you basically have to trial and error to figure out where the problem is. It could even be mobo, psu, etc etc.
Not worth giving any thought to drivers or game patches until after that's sorted.
