well, seems like turning off the auto restart on blue screen errors has prevented the shutdown. Now I just have to fix the part of the system that is causing the errors.
Quote from GTS:
Another option: do a fresh OS install in another partition (or another drive if you have a spare one).
Leave the fresh OS running for a while, if the spontaneous reboot happens with the new OS then it probably is a hardware problem, if not then its probably a software problem in the old OS partition.
So is it now staying on the blue screen? If so the blue screen has valuable information that can point to the source of the problem - just write down all the information you see, especially the "number of error (parameter, parameter, parameter, parameter) name of error" part and then google for it on the internet.Quote from Cache Landing:

I need another drive anyway as this one is getting full of graphics design and art stuff. When I get it I will take you advice, thanks.
Quote from gnome:
After you've gone to the effort of doing a fresh install, you might want to consider backup/imaging. Such a program and routine can save you tons of time in the future and mostly isolate you from the kind of problem you're having now. Suggest Acronis True Image and Casper XP 4.0 as the class acts.

Anyone want to make a suggestion as to the best spyware/adware scanners?
I used several of these for a month - settled on Spybot S & D. If I used it 1st, none of the others found anything at all. If I used any of the others 1st, Spybot S & D typically found something that they missed.Quote from optionpro007:
