I have a clients computer that is running at 100% cpu in normal mode. There are no applications running. In processes, system idle is generally at 99% with some small spikes for task manager. Checked for indications of spyware. The computer has been running AVG free edition (current on all updates), and WIndows defender (current definitions). OS is up to XP2 with all security / critical updates installed.

Ran Highjack this. Didn't find anything out of the ordinary. Turned off all non microsoft services with msconfig. Startup was already blacnk. No difference.

What really surprised me is that the same thing happens in Safe Mode. Again, no processes eating up CPU cycles but the cpu is still running at near 100%.

I checked the event viewer. No errors or warnings.

When I left the clients, I set it up to do a sfc /scannow to check the system files. I won't know the results on that until morning.

The computer was running fine a month ago (last time I was in). The owner wasn't available to ask about any new software. THe hardware hasn't changed since my last visit when it was working.

Ran a Linux Live CD (Puppy LInux) to do some basic tests on system operation. It worked wonderfully from the Live CD.

Any ideas on what to try next to troubleshoot this would be appreciated.

Thanks,

Bill
