I've just installed Win7 Ultimate to my PC. During the install it reboots a couple of times, but 2nd or 3rd reboot I see the "Starting Windows..." message, but followed by a black screen. No mouse cursor, taskbar, anything. The monitor power light is blue (indicating it has a signal) and it was displaying the setup wizard with no problems whatsoever.

Has anyone else witnessed this phenomenon?

Many thanks in advance.

UPDATE

I booted in safe mode, and got a screen saying "Setup is preparing your computer for first use". That's brilliant, although a message box has popped up over that saying:

Windows cannot complete instlalation in Safe Mode. To continue installing Windows, restart the computer.

So I don't really have the opportunity to do any cleverness with drivers or anything. I guess I could try getting a different version of Win7 (I'm installing from an MSDN DVD).
