Hi all. I've been having probs with system process running at 50-99% all the time. About an hour ago I reinstalled xp home. And I am currently typing with no updates or reinstalled software. Before all this happened, I moved everything from my old dell dimension 8200 case to a new kingwin case. I didn't change anything except the new case came with three fans. 2 in front and 1 in back. I've hooked the front ones to the psu and they have their own controller. The back one is hooked up to the MB. I've tried unhooking and rehooking them after rebooting computer with no changing results. Double checked everything and can't see anything I may have missed. Hopefully the MB or processor is not going out. Just can't figure out why system process in task manager shows it constantly running and it is hard to do anything because of lag.
