win 2k, processor 100% usage, spyware?

my friend is runing win2k and her computer runs very slowly (CPU 100% usage all the time)
first I disconnect the internet thinking it might be spyware but there was no improvment.  I also ran lavasoft adware which didn't find much.

next i ran win2k in safemode, and to my suprise the cpu was still at 100% usage.  Does anyone have any ideas as to what could be wrong?  I'm lost and I'd like to avoid formating.
thank you much

A module conflict. A sfc scan should resolve this issue.

Type "sfc /scannow" (without quotes) from run box in start menu.

Let me know.
I have found that some processes that come installed with HP computers can cause 100% utilization.  This link here may also help.
