Hi.....I have a PB P4 PC with Win XP Home.

I've not used Windows Disk Cleanup for a couple of months. Today I've tried to clean up my master hard drive (40 Gig, about half unused). Problem is it only really shows "Scanning : compress old files" and nothing appears to be happening. Task Manager shows Disk Cleanup still running, but its not getting anywhere. Also CPU usage has shot up to 100% throughout the 4 hours I've been running Disc Cleanup. Even when I close Disk Cleanup CPU continues to run at 100% and only returns to normal on re-boot.

At the same time I've tried to Delete temporary internet files and within a few seconds Task Manager shows not responding.

I've de fragged regularly and also run AVG 7.0, Spybot and ad aware daily.

The puter has been running a bit slow of late, hence I'm trying the Disc Cleanup. I should also mention that I ran Disc Cleanup on my secondary hard drive (120Gig, 75% free) and it completed in seconds.

Any ideas?

Thanks.
