Lately when I have been playing my higher end video games, Fallout 3, Dragon Age, ect ect... I have been getting the blue screen of death. From what I remember it said something about a clock interrupt. My CPU is an AMD Anthlon 64 X2 6400+ Dual Core. I'm not sure if it times out because it's too old, or if it could be because the cpu is over heating, or maybe it's vista just being a crumb bum. Any suggestions on where I should start looking?
