bad video hardware or drivers can easily crash the system
If its running an X windows display of any sort, I'd suggest trying it in text-only mode. in /etc/inittab, set the default runlevel to 3 instead of 5. this leaves the video in plain VGA text mode which is far less likely to crash the system.

Seconded. If it's a server, it doesn't really need X running anyway.
