Re: Squares all over - graphics card issue.
Do the dots appear in different locations or always in the same place, Could be either your monitor or that 780 crapping out on you, Could even be just a dirty connection to the monitor or the wire is going bad, Try disconnecting the cable from both ends (take it off the monitor and video card) Make sure all the pins aren't bent and reconnect and if you have another monitor or even a TV you can connect the pc to and see if it still has the issue, if it does that will remove the monitor from the list of possibilities.
