Explorer.exe constantly maxing out CPU

[ofelas 0]

Almost every few minutes, CPU usage in the task manager goes to 100% & the system freezes up for several seconds...on shutdown, the 'Ending Task' window pops up, trying to end Explorer.exe

 

Any thoughts ? This is on XP Pro build 2600 Corp ;-)

 

TIA...

I'm having this same problem, mine usually occurs after copying large files, mostly over the network. Only a reboot or killing explorer corrects it.
