Half of the pc screen is stuck at green/red, refreshes at every 5-10 sec.

Basically the title and the picture summarizes itself but half of my screen is stuck and refreshes at every 5-10 sec. This happened before (like 7-8 months ago) but dissappeared by itself. Now it happened again and it does not dissappear...  When I drag something black to that area, it turns magenta, when I do it with white, it turns cyan.  I am pretty sure that this is a hardware issue, because when I do Print Screen, the image becomes normal when I view it from another device.

So, I solved it for a while, than happened again. The problem is, I think the connections on the screen. I tried to slightly  push from the opposite corners of the screen. That solved the problem temporarily, but didn't last like 2-3 minutes.

Now, it is OK.
