Not sure if this is hardware or software, so I'm posting in both forums. User's pc is running slow. CPU usage shows 50 to 80%, but system idle process shows 99% with no rougue processes running. Ran Trend Micro Sysclean, Ad-Aware, HJT, all negative. Read something about SP2 causing this, so I booted the system with a spare hard drive with SP1 and no software installed. CPU still runs at 20-30%, with system idle process showing 99%, with only bare-bones hardware running. The only thing I can see hardware wise is some bulging capacitors on the mobo (MSI K7T Turbo2). Also tried swapping ram - no joy. Any ideas?

Try Safe Mode, see if this occurs as well. You could also temporarily disable the Startup programs with msconfig, see if there is an impact. Very unusual to have 99% System Idle Process and seeing high CPU Usage.

Seems normal in Safe Mode, around 2% cpu. Nothing running in startup, as no software is installed, only o/s.

Download hijackthis from the link below. Extract to desktop or prefered folder. Open the program and choose do a scan and save a logfile. Post the logfile on here and unless your sure of what your doing do not attempt to fix anything for alot of items are legit. Just going to see if by any chance somethings running that the other things might have missed.

If things are normal in Safe Mode, I'd temporarily disable the Startup programs with msconfig, then see what the results are in Normal Mode.

electronicsfreak, as mentioned in my original post, I already ran HJT - thanks anyway.

BFOJ, as I said, there was nothing to disable, as nothing had been installed except XP.

It appears I've got it fixed. I went into the bios and reset it to optimum default settings. Then it ran fine with the test drive, but when I booted back to the original drive, the cpu was still high. then I uninstalled McAfee, and now it's OK. Thanks for the suggestions.
