the blue or red screens of death are often some hardware error, like mis-matching RAM like I had. one 32-byte clusters, and the other 64-byte (I think it was). so it wrote stuff at 64 MB intervals until it hit the 32 byte card, trying to access non-existing memory space. that's the only reason for my bsod's from XP and forward. (fixed it while still on XP sooo now I haven't had any problems at all).
