  1. Hi all. I've got this issue with my graphic card (fresh and crispy by the way - 1 month old). Few days ago I was just browsing web when suddenly blue screen came out of nowhere on my Windows 8.1 desktop PC. Ever since then when computer boots screen is filled mozaic-like with green squares, after few seconds it's changing to vertical lines. Obviously Windows window manager won't open at all, and it greets me with black screen. After I deactivated graphic card, and switched cable to main boards VGA port computer runs ok.

    I've seen some similar threads on techspot suggesting that due to escessive dust 'consuption' GPU can overheat and irreverisbly burn therefore. Is it possible that the same thing occured here?

    It's what I've seen on the screen when one of my graphics cards has died. As it's almost new changing it shouldn't be a problem. It's more likely to be a faulty graphics card than dust. Double check that it's seating properly in its port and that the video cable is OK.
