Windows 7: Need Help Restoring my laptop to factory settings!!

Okay, so i turn off my laptop for the night. I come home from school the next day i turn it on.
My laptop freezes, after a while a blue screen flashes and the computer turns off. Then i turn on my laptop again it does the same thing.



So i decided to i have to restore my laptop.
I press f8 and it brings me to the menu
i click on repair your computer
then it brings me to the artistic blue screen background but nothing pops up. I know there's supposed to be a box that pops out that gives you some sort of option but it doesn't. All that shows is the mouse cursor (i'm able to move it) and the blue background screen.

Any suggestions on what i should do?
Thanks guys.

Work through these steps using the System Recovery Options on Windows 7 DVD or System Repair Disk: Windows 7 fails to boot

Report back on each step as there may be other tests needed.

I would Check the hard drive with the manufacturer's diagnostic tools.

HD Diagnostic

Also Check your ram.
