Windows XP Pro, 1024 M ram, 80GB hard drive (7200)
Recently, my computer has been running very slow, although I cannot recall having made any significant changes.
Programmes take a long time to open, and sometimes the mouse feels "sticky" (not dirt).
The Task Manager shows constantly high CPU usage 70-100%, most of it under "system" process). What progrmmes hog this "system" process.
