Damn, you seem to have some bad luck with your computers
The notebook with XP on has crashed maybe 1-2 times during the year I've had it. But it was my own fault. I filled up the harddrive, so there were no room for temp stuff.
The computer before that (had it for 2 years) was pretty solid too. Only Windows that I've had real luck with is XP, Win2k crashed a little more than XP.
