Nightmare

So, I got my computer back (I shipped it via UPS from Portland). And I set it all up, turn it out, check out BIOS for about 10-15 seconds, staying around low-mid 30s. I boot into Windows, load up Windows and start Winamp, and walk upstairs. About 3 minutes into the song, the song stops and there is loud beeping. I run out to see what is the deal, and it is BSOD, and it reboots before I can read. So, I go to BIOS and check temps. CPU: 70C!! I shut it off immediatly. I take the side off the case and try turning it on again, but the fan doesn't turn. I turn it off again, and realize that the fan had shifted slightly and was caught on the heatsink. I reset it and everything works fine. Needless to say I almost sweat a bucket. Which is kinda interesting, because, that means, I can boot to Windows and play 3 minutes of an mp3 on passive CPU cooling :-D
