My computer gave the following message: We apologize for the inconvenience, but Windows did not start successfully. A recent hardware or software change might have caused this. If your computer stopped responding, restarted unexpectedly, or was automatically shut down to protect your files and folders, choose Last Known Good Configuration to revert to the most recent settings that worked. If a previous startup attempt was interrupted due to a power failure or because the Power or Reset button was pressed, or if you aren't sure what caused the problem, choose Start Windows Normally. Safe Mode Safe Mode with Networking Safe Mode with Command Prompt Last Known Good Configuration (your most recent settings that worked) Start Windows Normally Use the up and down arrow keys to move the highlight to your choice. Seconds until Windows starts: 30 After I made a choice the screen flashes and then it reboots over and over with the same screen. I have not changed anything recently. I have not added a printer, camera, or any other device. I have not uploaded any new programs. So, I decided to unplug the computer. Well, now when I turn the computer on the monitor is blank!!! Can anyone help?
