This could be a video card issue... You might try this... Turn off and unplug ALL wires connecting to your computer... Now... Open the compter case on a table ABOVE a tile floor... NOT a rug floor (static electricity), and immediately ground the electricity from your body by touching the INNER netal frame of the computer... Noext, find your video card and try pushing in on it softly, but firmly. After, just put the case back on, and plug your wires back in, and see if it works.
