ok i don't know to much bout computers, but mine randomly shuts off like its overheating, but the fan on the motherboard and fan in the powersupply are working. the HD feels warm, but not oww that hot i got burned. it only seems to cut off when I'm viewing a site that has alot of flash or junk on it. andi have removed the side cover and it still does it.
its a compaq presario 5000 from 2k1 lol. i know its not a memory problem I THINK cuz i dumped all the pictures/music useless programs.
