Hi, Recently formatted PC and every game I've tried.. Oblivion, FEAR, Planetside, Dawn of War, Dark Messiah (this is by far the worst) all crash on me the same way sooner or later. I run a AMD64 3200+, gig of ram, 7800gt and only had these problems with dark messiah before formatting -- I'm pretty sure ive installed all drivers I need... graphics, mobo, processor, sound an all that jazz. The games run as fine as my system should run them (most at about 60FPS with settings I'd play them on) then suddenly totally lock up - screen freezes and sound loops about 1 second of itself for abit then just merges into a big horrible BUZZ OF DEATH that rattles through my room then PC hisses and what not then decides to reset. At a lost end -- dreading its an evil hardware problem but I really really hope not because I hate going in there and fiddling about with stuff I dont quite understand haha -- I put it together myself.. probably half the reason this is happening. Like I said though ran fine before format which makes it strange. Thanks in advance!
