    My W520 arrived and after factory install I got artifacts on screen. They look like 1 pixel dots which are pulsating. Sometimes there is no artifact on screen, sometimes hundreds and I am talking about idle desktop usage, like desktop background.

    Based on HW monitor temperatures are low - CPU 49 C (120 F), GPU 37 C (97 F).

    I tried a fresh install on my SSD, and it is the same. I also updated the machine BIOS, no change. I am working on dock 3 plus, my external monitor is connected via DVI. When I undock, I cannot see any artifacts. I am using discrete only setting in the BIOS, because the external monitor doesn't work with integrated only to check if the integrated do the same.

    Do you have any ideas what to do? I looks like graphic memory failure to me.
