Hello everyone! I've got a problem with my Lenovo y520, bought about 3-4 months ago, I noticed that sometimes one white line at the bottom of the screen may appear out of nowhere (see screenshots), though it usually appears when I'm playing games. The line stands just at the bottom part of the screen, more exactly at the bottom part of the task bar. I must say that this problem didn't start to occur when I bought it, but after a while. Also, I noticed that while I'm playing video games, the screen would flicker (like a very short shut down) for 0.1 seconds, if you blink you'll literally miss it, and then the line appears. Sometimes, the screen flickers again and the white line would disappear. This problem doesn't occur everytime I play, but sometimes. The white line remains still, unless I restart the laptop.
Now, I'm asking you for help, what is the cause of this problem and how can I solve it resulting in no appearances of such weird lines on my laptop's screen?
