service pack problem
when i first got my computer, it ran all the service packs and windows updates fine. but when i installed my new video card and PSU, my CPU usage stayed really high. so i installed XP without any service packs, and it was fine , but i decided to try installing XP with service pack built in, and AGAIN my CPU usage is running high. whats the problem here?
btw, its a compaq sr1830nx. and i KNOW the hardware is fine because i ran it 7 months without the service pack and it was good,and that was with the GPU and PSU.
