Tried new hard disk, still same problem. When I actually got the pc it took about 10 minutes before xp would even load up and when it came up it took about 10 more minutes before I could even click on a username. Someone had been messing around in the BIOS and enabled OS install mode which limits the system to 256mb ram, so I disabled it giving back the full 512 thinking that may help. Also, I'm trying to do a fresh install. I've already deleted the partition so there's nothing on the HDD anymore. I'm thinking maybe it's a problem with the RAM.
