Well, been having some problems with my PC over the last few weeks. It will run fine, temps around the 50s with AMD XP 2500+; however, when running a game, even older games like Diablo 2, every so often the computer will shut down. Inside my PC there is a lil green light. Right next to the light on the motherboard is the word FAN 2. When my PC shuts down, the light turns red, and the only way to boot the PC again is to unplug and replug it. I have no fan 2, and in my BIOS the only fans that work are 1 and 3. If anyone has any idea on why my computer crashes like this during gaming, please let me know. Thanks.
