When I boot up my computer, I get a horrible video error when windows xp tries to boot. It looks like the screen you would get on an old 8 bit NES when the game wasn't inserted correctly (not that purple screen, the one with all the weird multicolored blocks and stuff). I'm not sure what's causing it, but it's gotten more and more frequent over the last few months, and now it happens pretty much every time I boot. My ATI AIW 8500 DV has been getting very hot recently (almost to the point where it burns you when you touch it) even though the fan on the heatsink is still spinning. Should it be this hot? It's still under warranty, so I could RMA it, but I don't know if that's what's causing it and I don't want to risk the downtime unless i'm reasonably sure. It could also be the mobo/cpu/memory since they've been a little glitchy now that I've started using the SATA. I wish I had another agp card lying around to try in the system, but I don't. Any advice on how to troubleshoot this problem?
