Windows XP Pro repaired with XP home disc
512 MB 2100 DDR RAM
Athlon XP 2000+
I have a problem with which either System or services rapidly fluctuates between 0% and 90% of my CPU Usage. It tends to be around 60% most of the time, and the rest of the space is taken up between by svchost. it first started happening about a week ago when playing games. the my computer would start off fine and then get to 100%, slowing down my game. I figured this was because the ram at first, but ran scan disk and ad-aware anyways and it seemed to fix it. It would still show as 100% in game, but didn't affect gameplay, and went back to normal outside of the game. It worked ok for a few days and now it's back and not working again. it shows as 100% constantly and my computer slows down slowly untill after about 10 or 15 minutes, even idling, it all but freezes (as in I can move my pointer but not do anything)
I've tried virus scan, and I've read a few more topics on this, but haven't seen anything that was my problem. any help you can offer would be appreciated, and if you need any more info, I can supply you with it easily.
