I turned my computer on today to find that it is incredibly sluggish. I checked the processes, and System Idle Process is at 99, but CPU usage is 0%. No applications are running, and nothing is running in the system tray, which is odd because Rage3DTweak and the nForce2 control icon normally reside there after startup. It was fine before I shut it down, and it was shut down for about 2 days. I can't get into anything (like Control Panel) to try to fix it, and Windows won't let me stop the offending process. Any ideas/solutions would be greatly appreciated.
