So, i have a Toshiba laptop with windows vista and recently i busted the screen. so we hooked it up to a Dell computer screen, so we could still use it. It was working fine, but recently, when i turn it on, it will load and then this screen comes up thats says "windows was not shut down properly" and gives me the options to start windows normally, safe mode, safe mode with networking, or safe mode with command prompt. when i start windows normally, it will load, but instead of going to the log in, the screen will just go black. But it will run with i run it with any of the safe modes. Anybody know how to fix this?
