Try pressing "Fn+F8", if that doesn't work then try booting it with the Windows Setup CD in the drive. If nothing works then try pressing keys like "F2" or "F8" or "Del". If that doesn't work then I'm sorry, I can't help you.
***EDIT***
I missed out the most obvious solution of all- it could just be the screen, so try attaching an external monitor to see if that works.
your computer must be broken.or hacked
If a blank page keeps appearing on the computer screen, it is a good possibility that the computer is trying to download a program that the user has not authorized. To get rid of this blank screen, the user should run a virus protection program scan. A system restore can also be used to restore the computer to an earlier time before the blank screen started appearing.
