Thanks Robin. I did that and found lots of information. The problem is that the screen is black and the cursor won't move. All the instructions need me to be able to access the problem computer. Guess it will need some sighted expert help. Fingers crossed.

Looks like a system restore or some work in safe mode is required, sighted help I guess?
