need help. So like, i had three screens up and running. Then my cat knocked over my computer when it was on. I turn it off, everything is fine, except that only two screens work. They are on and i can rearrange.. but only two screens will turn on. In the display settings, it says the screen is connected by the screen is black except it says "power saving mode" and the button just flashes.

It sounds like the monitor cable connecting it into the tower is not working. Try using a cable from a monitor that works and use it on the effected monitor. If it works, its just the cable.
