Thanks guys. I've tried a lot of different stuff today - spent hours on it to no avail as yet. I've just unplugged all my USB things, except mouse and keyboard and am going to reboot and see what that does. I'm pretty sure it was something to do with the fact I had a 4GB memory stick attached and it was probably just looking at it in order to put up the 'My Computer' display. The trouble is, I've taken that out and it's as if my computer doesn't understand that. Let's see what a reboot now does.

What I'm left with after that is a restore. What do you think of this:
1. I have an Acronic back up from a month ago.
2. Backup my Windows registry.
3. Fire up Acronis
4. Restore last month's C:\Windows folder (and subfolders)
5. Exit Acronis, reboot.
6. Restore registry from 2.

Is it ok just to restore the Windows directory on its own like that?
