A few days ago everytime I turn on my computer and start it up it goes through the booting up black screens but then stops at the screen that says "its safe to turn the computer off."I restart it and it says "Windows did not start properly." then I can run it in safe mode. The next message is "The adapter type is incorrect or current settings do not work with your hardware."I have changed the settings but each time I start up again the same problem exsists. It takes about 4-6 restarting before it will stay in the correct display settings. I got a new hard drive in September, have Norton anti-virus and nothing new has been added recently. Any advice?
