If this does not end problem, the video card is not making firm connection into motherboard. Turn off computer, remove case cover, and locate video graphics card. It is the one that cord from monitor goes into. Remove monitor card from video card. Remove screw (on inside back of computer) that hold video card in. Remove video card and reinsert firmly. Screw retaining screw in firmly and reattach monitor cord. Replace case cover and you should be back in business.
looks like a graphic card problem. Turn off computer, remove monitor cord from computer and reattach. If you can remove from monitor end do it also, and reattach.
