Windows 7: [URGENT] Black screen

I've been using Windows 7 for about 2 weeks and I didn't have much issues with it. Today when I turned on my laptop, everything was booting fine until the welcome screen where I enter my password to log in. It gives me a blank page but it's not loading at all, I see my mouse not to mention. It's working fine when I boot up from safe mode though, that's how I'm typing this :P.Anyways, I really need someone to help fix this.

Hey, and welcome to the forums!

First things first.. Please fill in your system specs so we know what we're dealing with...Help us help you... without your specs, were just shooting in the dark...
What version are you trying to install etc, etc .... information Will Robinson, we need more information!!

Did you hook up an external monitor or television before? The desktop is probably now on that display, even if it's unconnected. Try to disable it somehow in safe mode or choosing most recents setting that worked at the f8 boot screen. Or a System Restore to when you know it was good.
