Try booting in safe mode and see if it allows you to get to the desktop. In Windows 7, you could run a repair install from the advanced startup options (Frequently Press F8 just after starting the system). Run it atleast 3 to 5 times and focus your eye on the error it produces.

Post back with your result.
