Screen Issues, flashes of black and white

[LizaEsca]

Hey guys, 

I am having a huge problem that seems to happen when it wants to, or when I feel like the laptop itself is touched wrong on the keyboard area. I am experiencing a huge issue where I can be using the mouse pad, typing, placing the laptop down, or sometimes nothing at all and my screen decides to flash with white/greyish boxes there is no noise that occurs, the screen just decides to act up like displayed in the picture provided. For them to go away I have to turn the computer off and by that time the computer has trouble turning on. I don't know what to do or what it could be but I am hoping to find a solution one way or another.

First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.
Rinse and Repeat

AND/OR - Power on your PC, press Esc (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).
