When I received the tower and hooked it up the screen was black with a blinking cursor. I called tech support and was told that I needed to buy a new monitor. (I didn't believe that but thought they they would know better than me) I purchased a new monitor and what do you know a black screen with a blinking cursor. I was told by the tech that I could send it back. What a whole lot of trouble and plus I would again be out of a computer. I am online right now watching videos on how to fix this black screen. It has alot to do with the operating system ( which I mentioned in the first place).
