I can't do anything with it at all!Please can someone help me? 1 person needs an answerI do too

Can you get into Safe Mode? Repeatedly tap the F8 key as the computer is starting up to get you to the diagnostic menu. If that doesn't work, try Last Known Good Configuration from the same menu. If that doesn't work, then we would need more information about the computer and its recent history to narrow down the troubleshooting. You could be experiencing hardware failure or Windows might be damaged from malware or other software problems. There is no way to tell from here without knowing more.If you can't do the work yourself (and there is no shame in admitting this isn't your cup of tea), take the machine to a professional computer repair shop (not your local equivalent of BigComputerStore/GeekSquad).MS-MVP - Elephant Boy Computers - Don't Panic!
