Yesterday I installed Windows 7 Ultimate 64-bit on my girlfriends computer for her. Everything installed fine and I installed all her applications, office etc and it all seemed to be working well. It did a couple of Windows Update cycles and all seemed well.
Today, she has turned on the machine and it has processed more Windows Updates, but now the computer just boots to a blank black screen with a mouse cursor, but you can't do anything.
We have tried repair options, but I system restore says there are no restore points (Really??) and other repair options seem to do nothing.
Even booting into Safe Mode just bring a blank screen and cursor. We can't use windows shortcuts to open command prompts or anything, and not even ctrl-alt-delete works.
I've googled the problem and can see a LOT of people have experienced this, but see little about a fix.
Has anyone ever come across this and managed to fix it without reinstalling Windows from scratch?
