Hey guys. It's not an old computer or anything. AMD Athlon X2 processor, NVidia Geforce 7900 GTX graphics card, 360GB SATA HDD, 2GB RAM, the works.
The problem is, that a couple days back one of the fans died on me. I kept it off for until I could get a new fan, which was no big deal. Plugged it in, powered it back up, etc. However, when it powered back up, it would receive power for a brief second (if that), then just completely turn back off. All the fans would start spinning, the lights turned on, and everything, but it turns off almost as soon as it turns on.
