I have a win2k pro computer that is running super slowly. It seems that the "system" process is using 100% of my system resources.  Everything else seems to work, albeit very slowly. It takes up to 10 minutes to load windows, and oncve loaded, every other program takes forever to load as well.  HELP!!???!?!

Is that "System Idle Process"  ??  If so you have a hardware issue. MSGeek

it is not the system idle process, it is the actual process "system" that takes 99% of the resources.

I have run spybot, spy assassin, and pest patrol, to no avail.

i have a new harddrive that i installed, then i ghosted the old HD to the new one, and it runs the same, the old HD had a few bad sectors, but this one runs exactly the same, so i know its not hardware.... i am thinking virus, but i still have to run hijackthis.....  get back to you tonite
thanks for the help

Fantastic fix!  Worked like a charm.  System was a little slow in shutting down, but did in a reasonable fashion and came back up sans-problem.  System back to normal.  Go figure - a hotfix from M$ that breaks the OS.
