CPU usage at 100% with nothing running

Postby gaviota » Wed Sep 11, 2002 12:06 pm

Today I noticed my PC was slow. I opened the task manager and CPU usage was at 100%. The process that uses about 97% of the CPU is called "system" and the owner is the user "system". I tried restarting the PC but the problem persists.
I also tried running Norton Antivirus and Ad-aware to check for virus and spyware, but nothing was found.
I have Windows XP all the updates available from the Microsoft webpage.
Any clues to solve this problem?

Alot of the time this is a result of a bad driver.
I have seen this for instance when people have installed Sound blaster cards and the drivers they use cause this.

I haven't installed any new drivers. The only thing I've installed this week is a kids game for my 3 year old son. I'll try uninstalling it to see if this game is causing the problem.

I have seen this on systems with communications software installed that will poll the serial ports (or others) to determine if there is any incoming data.

It actually isn't a 100% load, but looks like it on a meter...because the activity is every few cycles.
