Thread: Windows 7 Booting up

I have Windows 7 installed on a computer. My computer is used at work to test headset compatibility, it is always left on. Yesterday when I try to use but the hard drive doesn’t wants to boot up. I think it is registration issue. What I need to do in this situation please help me out from this issue.

I want more information. Does the system start at all? At what point does the system stop booting? you get any error messages?

The system boots up, but the screen is blank. I don't observe Windows loading either. My monitor power button blinks on and off. The HDD lights up but turns off and doesn't light up or start at all.
