Also check whether all cables are still properly plugged in.

I've seen once an win nt machine with a bluescreen which disappeared after plugging the PS/2 mouse right back into it again.
Since then I'm careful regarding cables and plugs.

When you find a big kettle of crazy, it's best not to stir it.
