I was trying to setup a second display with my laptop, but the second display wasn't connecting. I set them up as 'extend monitor' and clicked Ok. The monitor of my laptop froze, displaying only the wallpaper and nothing else. The secondary monitor kept on being non-responsive (but I suspect a bad cable).
As much as I tried to revert the changes, my laptop wouldn't take any command and the cursor disappeared. I shut it down to perform a restart. Everything went normal until the time came to enter my password. The screen remains black and I cannot do anything.
I can access safe mode and use it normally, but I can no longer do a normal start.
I am using windows 7. The laptop has never had similar problems.
I tried alt+ctrl+del to no use. The display settings in safe mode are normal. The secondary monitor is disconnected.
