The screen is on when the computer starts up but after about 15 seconds the screen turns black. The computer is still on and functioning as far as I can tell but i cant see anything to make sure.
Ive had the issue before when I updated to windows 8.1. That time i think it was due to the aftermarket video card installed on the computer not working well with the windows 8.1 update because I switched the graphics back to what came on the computer and the screen worked again.
The issue I am having is that I dont know how to change which card the computer is using without getting to the desktop. (The previous owner set it up so that you could right click and switch graphics cards) but i cant even get to the desktop before the screen goes black.
I just restored the computer to factory settings and was able to go through the whole setup process and even get to the desktop but after a short time the screen turned off and now I am back to where I started...please help!
