[ginnyw4]

I have a HP laptop running Windows 7 Home Premium. Although the computer turns on, fan is running, etc. I am unable to get a start up screen. Can anyone help?

Can you connect to an external display? If so, you might be able to see an image. If that works, you may just need to change (use the function keys) to set the proper output device. If that is not the issue, it could be that your internal display is the problem.
