The last thing I tried to do when my last computer died was burn CDs. It was actually while burning CDs that the computer rebooted for the last time and fried. So I finally have my computer and CD burner set up and lo and behold, on an entirely new power supply, the same thing is happening. the computer hasn't died yet, but it has been acting suspiciously like the one that did. First, it refuses to burn at anything above 4x - it doesn't even list it as an option. When I try to burn at 4x, it likes to reboot. I've successfully burned 2 CDs out of six attempts. The problem could very well be software because I'm using the same Windows installation that I used on the previous computer, but there seems to be a hardware component as the computer is getting insanely hot. But it could be the software putting the hardware in a power-intensive loop causing the overheating to occur (the fans work fine).

Anyone familiar with this unique combination of issues?
