Does the screen come up when a key is pressed? You can try and change the general display settings.


For Vista and Windows 7:


Go to Start--> Power Options --> On the left side click 'Choose when to turn Off Display" and change The Turn Off the display to Never or increase the time.

Also disable any screensaver.


This can also happen if the system is still infected by malware or sometimes due to file corruptions after virus removal.If it is due to one of these reasons then i would  recommend to backup all your important information and then perform a system recovery i.e reset it to factory settings.


Recovering the OS or Reinstalling the Operating System

Your problem is: the windows you are using is not genuine or the serial number entered to register the windows product is not valid. Microsoft verified your copy of windows trough windows update witch is set to automatically.


Resolution: You must provide a valid Product Key for the version of windows you use, XP, Vista, 7.
