(Lack Of) Windows Stability

Pet Peeve with this PC. Sometimes the computer crashes. But what is strange is that it seems not be the PC that crashes itself - it seems to be the video system that crashes. It seems that all the system resources get taken up, and nothing can be done to fix things. CTRL-ALT-DEL fails. Or more correctly they work, but not well.

One time when it recovered after some persuasion (today) I had about 30 copies of the Task Manager running. That took a lot of resources I can tell you. Argh.

I am hoping that XP Service Pack 2 will fix the problem but I am not confident of this.
