Most blue screens happen when windows is booting and it usually gives a decent error message.
That's not my experience. I usually got the death notice when I wanted to save the last of 20 changes to a project, went to do it and lost everything .
On which OS? What kind of project? How much RAM do you have? Give me the details and I will gladly show you how the error is yours and not the OS. Do you have Bonzi Buddy installed? Gain? Save Now? Hit control-alt-delete and tell me which processes you have running.
Computers don't screw themselves up, people screw them up.
