I recently upgraded an Asus P4B533 board to a 2.66Mhz P4. It runs XP. I download the newest updates at the MS site, and updated my Norton AV, and Spybot, and ran checks on everything. Worked fine.......I loaded up my new TurboTax (2003) and then downloaded the California patch to the PC.
I shut the machine down and left for a few hours.
Came back and tried to go on line, and the PC was very slow. TskMgr resource meter says system (not system idle) is using 100%, and my Norton AV is turned off, and won't scan. Ran all the recent worm detections, and can't find anything?
Any ideas?

Check for CPU overheating. Check fans. Turn everything (software) running in background off, then reintroduce them one at a time and see which one triggers the problem. How much memory do you have?

check the running process list to find out WHICH process is using all the cpu

Your going to have to break down the system process into threads and see which thread of the process is causing the leak... Let me know if you need help.

defragment, checkdisk, and remove temporary folder files. Try to remove things you do not use very much. See what that does.
I would not hurt to try.
