I have a general question on VISTA. My parents recently bought a new laptop
with Widnwos VISTA loaded. The computer worked fine, but recently has
started blue-screening after it starts. I know this may be a shortage of
information to help diagnose, but if anyone has thoughts, I would appreciate
any ideas. Here's some additional info.

Computer only blue-screens if they have an internet connection (wirless or
LAN connection).
There internet provider is a small local telephone company who set them up
with a static IP.
Only third-party software added was Norton AntiVirus and an Anti-Spyware
program.
