I have a powercolor 3870x2 that only worked after reseting my motherboard bio's making me believe it was my motherboard crashing causing the problems, also almost every time I play a game my computer would crash. One day at a lan party my computer would not stop crashing but I realized after one crash that I still had sound only my radeon card was crashing, the red led's on top of the card was flashing sometimes staying on. I look inside my case closely looking for anything odd, even taking the card out a few times, nothing looked funny but then when putting the card back into the PCI slot I notice the numbers running along the edge of the card was not lining up with the PCI slot. The people a powercolor pulled a fast one, the cards are printed crooked not lining up with the PCI slot the only way I can get my computer to stay on is to take the backplate off and shove a McDonald's toy underneath it....... DON'T Buy powercolor or any ati cards trust me this the the second card from ati that I had problems with.
