Computer displays startup but goes blackscreened afterwards.

Hello,

I've got a pavillion dv7 running windows 7.

When I start the computer, it goes to the screen that informs me of an unintentional shutdown and asks if I want to do safe mode or continue normally.

Normally: The screen goes dark, goes into the windows startup screen, and then goes dark again. I can hear Skype and other programs starting up through the speakers but nothing I can seem to do reenables the screen.

Safe mode: Everything is safemode normal, big and stupid looking. I'm not too sure what I can do through safe mode besides scan for viruses.

How it started: This morning when I woke up, my laptop was shut off for some odd reason. I turned it on, left for a while, and found the screen dark when I came back. I tried one more time to turn it off and on, and I got a couple hours out of it before it went all funky and shut off. By funky, I mean the screen turned a sort of overlay of blue (patterned, not random) over everything else (translucent so I could still see what I had opened and the screen below) and then it goes black.

After that, I haven't been able to get it going again in anything but safe mode.
