Right, update, I think the whole computer is pretty much DEAD! I have triedd almost everything to get it back up. When booting, hard drives often arent detected, the BIOS crashes, and windows often produces BSODs of "HARD ERROR" and after about 30 seconds, reboots. I have removed eah stick of RAM, with 1 in, it runs at 400MHz, but it will crash after about 5-10 minutes use, and do other od things, with 2 sticks of RAM, youre lucky if it gets past the POST. I havent enough money for a new computer, so I think I'm going to get a Pentium IV 478 and hav some fun overclocking it!
Any other ideas as to what the problem could be are welcome!
