I have a Celeron 2.5Ghz 512mb RAM e-machine on my network.

It runs on Windows XP Professional and is part of the domain.
The system freezes up sporadically.

The CPU usage shoots up to 100% and the system gets hanged with the EXPLORER.EXE making the highest mem usage.

If system is restarted, then everything is normal again for a while; but it occurs again.

I have done a Symantec virus check and a spyware check with nothing getting detected.

I browsed through some forums and found that some bad avi files could cause that problem. But the system does not have any avi files except the regular files inside the Microsft Works folder.

Is there any other workaround/patch/solution available?

Thanks,
Saravan
