    Super weird graphics artefacts

    Hey there. Kinda from out of nowhere I ran into this strange graphics problem. I was playing Battlefield 4 and needed to alt-tab for some reason and noticed that I was getting weird pixel artifacts on my desktop. So the first thing comes to mind is that I'm overheating my gpu and that's causing the issue, however, even when cooled they have stayed with me. Here is a picture to better describe my problem: http://s11.postimg.org/7es6trf2r/Clipboard01.png

    To further dismiss the overheat issue, I open up my laptop (it's a 6 month old clevo 170sm, with 8gigs of RAM, i7-4700mq and 8970m), clean the fans (even though they were not too bad in the first place), turn the pc back on again and check the temps I am getting with speedfan and it's certainly not hot, the gpu and cpu are staying around 40 on idle or browsing, etc. And under load, (again battlefield) they go up to 60-70max. The venting is good, the heat paste should also be awesome (IC diamond or similar).

    Then I think, that in any case I might have busted the VRAM of the card, so I figure, I should try to uninstall all ati drivers, and use the discreet gpu of the intel, so I do the full manual uninstall complete with the registry keys, etc. and again the problem seems to persist.

    The pixels sometimes flicker, they appear and disappear and I'm also getting some minor screen tearing and weird yellow color bleed from time to time, where I get yellow streaks appear randomly in the background of pages. Also some times characters get itallic for me, or take some other weird unreadable shape, the problem seems worse when the color is set to 32 bit, than in 16 bit.

    I'm kinda baffled what it could be and any advice or solution would be appreciated.


    Edit: Also forgot to mention I did the windows memory test to check the ram with no errors and also ran the VMT program to check the vram with no errors too.

    The screen shot provided is something new to me. If you hook up an external monitor does it do the same thing? Could be the screen going bad.

    Did you reinstall the Intel graphics driver? It could be a faulty iGPU.

    This would be my first thought too. External screen will at least help you eliminate a few possibilities.

    Does this happen only during gaming or at random?
