I have had these crashes too, but only when I tried to make wireless internet connection. These blue screens are weird, most common the actual origin of the problem is hard to find out, it could be an old or corrupted driver, but mostlikely you have a hardware failure, that somehow windows detects while, in your case, activating msn. (At mine, it was detected while activating the wifi driver). Then where is the failure? We don't know. That's why Acer is probably slamming a new motherbord into my computer, or swap the whole device. (It's still getting repaired of it
) Probably you have had these crashes before (sporadic) while msn still worked... it goes from bad to worse. Try formatting your computer, that's the easiest way to find out, if it still crashes while using msn then, you'll have to send it to your computer back to the manufacturer.
