I tried to open my pc and when its in the loading there are blue stripes boving around. when loading finished lock screen come for about a blink the screen turns black but i can still log in and play around with the scree. I tried connect to hdml with my television and play around for a hour the problem is gone. But, after 1-2 days the problem went back again. When i press start button the screen blink again and when the app is loading the screen work but when loading finished screen turna black again. I will try to make video that show you the problem

Try to explain it better- your post is hard to read. Open PC while in the loading? What you mean, "Open"? The case? Play around with the screen? Huh?

Are you connecting to TV via HDMI? Check your screen resolution settings.
