I'm getting the black screen of death myself, and I've followed the advice. I'm also having some in-game issues when I'm not getting the black screen. COH runs relatively smooth...relatively, but COV is choppy. I'm honestly thinking of returning this computer and getting a different one WITHOUT the damn vista home premium. I got the computer for gaming, and it appears to me that trying to run games under vista is just an uphill climb the whole way. That aside though...it's slowed a bit on COH, but not bad at all...it's very jerky and temperamental. It often freezes for a couple seconds, and it's all around very unpleasant. Anyways, I'm for lack of a better word...COMPLETELY computer stupid when it comes to trouble shooting. So if you have advice keep it withing the grasp of a computer moron. ^_^ (or just tell me that I probably shouldn't have gotten a vista before they worked out the kinks...=/ cause I'm thinkin' the same thing.)
