Hi. I don't know if your're talking about a BSOD or not. Have you tried to restart Vista in Safemode and when you come to that Options screen choose "Start Windows with the last configuration that worked". If this doesn't do it, then chose a "Repair" at the Safemode Options screen.
It sounds like a driver issue. Has your neighbor installed anything or update anything right before the issue appeared?
