Background:
I have been having some problems with my Windows registry today. It looked like antivirus had corrupted my licensing data. When I booted in to windows I would receive a message about:
"an unauthorized change was made to windows 7"
and telling me I needed to repair it. I followed lots of tips from windows forums, but I just kept hitting permission errors and nothing worked. Anyway, I managed to fix this by using an activation crack.
However, when I now boot-up Windows, just after the password screen (I dont bother with a password on my home PC) the signal to my monitor cuts off temporarily for a few seconds, and then turns back on again.
I installed the latest driver for my graphics card, but the problem still exists. It must be something to do with the registry/the activation crack did.
What could I do to repair this? When I had the initial problem I did use a Windows 7 repair disk and the startup repair tool, but it couldn't find any problem.
Update:
Found this which is the same issue:

and somebody replied:
As far as I know its basically happens because the systems switches over form "driverless mode" to using the nvidia drivers.
