    I7-3770 HD 4000 screen flicker




      I have been reading about the rash of problems about screen flicker and video problems with people running this chip.  I have the same problem.  I have updated the drivers to the latest from Intel using the driver update tool.  I also ran the Intel Processor Diagnostic Tool and it passed fine.  I am still getting screen flicker, although much less then when I started.  My biggest problem is watching youtube videos in full screen.  There's lots of ghosting flickers of random colours and static.  I have the same HD4000 graphics on my laptop and I can watch the same video with no problem. 


      So far I have switched motherboards (new board), switched RAM around in all the combinations (1 stick, 2 sticks, different DIMMS), OS fresh install, but no luck. Problem is still there albeit getting better with each new driver.
