Windows7 Shutting down over and over again

I opened my laptop this morning and now I get a black screen with a message saying Wondows instaltion was not sucessful... (I didnt not try to install anything)

then after 5 seconds a blue screen comes up saying Windows is shutting down. This repeats over and over again.

I cannot access any desktop, shut down, or admin log in

I pulled the battery
I tried Ctrl/Alt Delete
I tried F8 safe mode

I have not tried throwing it against the wall yet, but it's a possibility

Any advice would be appriciated,
Thanx

Throwing it against the wall isn't usually covered under warranty, but other than that it sounds like a great idea.

Just kidding.

Have you booted to a live CD to eliminate hardware issues ?? I'd do that and put it through its paces as much as I could, assuming it boots and runs the live OS.

Try that and we'll go from there.
