I currently have a 550 p3 on a soyo ba+ motherboard with 128 MB RAM. I have a Maxigamer cougar 32 MB tnt2 card, a diamond monster voodoo 2 card, a 13GB maxtor 5400 HD anda 20GB maxtor 7200 HD. I had my system on the 20 GB and recently the computerwill run a program smoothly for about 5 minutes then starts to get really choppy. This happens mostly in games, but even after exiting, the rest of the system has pauses in it. I ran norton utilities and once it gave me an error that the drive size is being reported incorrectly. It repaired this problem and was fine for a few days, then it happened again. Getting tired of it I formatted the 13GB drive reloaded everything on a clean install and everything seemed to be working then it startedhappening again. I am looking for any suggestions. My first thought is that the system or processor was getting too hot, but this does not make sense because the machine was working fine for weeks since i put the 550 processor in. Any suggestionswould be great.
