So everything is back to normal and you get a blue screen as soon as Windows loads. Try pressing F8 while Windows is loading so you can select Safe Mode and see if that works.

See if it will load with a different OS. You can download a Linux Live CD which will let you load Linux without installing it. If it works then it is probably a software problem. If it doesn't then hardware.

Also when you get a blue screen there is a bunch of numbers on the screen. Those aren't meaningless. Try searching Goolge for the info on the blue screen. It probably wont find anything. If you call MS for support they will be able to tell you what they mean.

Hint. If you call MS for support and tell them the following you can get free support even if your warranty is expired or if you never had one.

You purchased Windows recently - I think within the last year but be safe and say last month.
It did not come with your computer. You bought it by itself. Otherwise they direct you to the hardware manufacture for support.

You do not have the original CD. You are on vacation or something and it is at home or at the office. Other wise they ask for the serial #s on the CD and check your warranty.

You can not boot into Windows - you are on a blue screen. Other wise they get the serial # and you are busted. Even if you can boot into your computer you can probably still tell them you can't. The first person asking for info is just a gate keeper. When you get to the second person you can tell them the real problem and they don't care about warranties.
