What this might be

Never over clocked. Laptop has 1 and a half year.

Just suddenly started to jump up and down, mostly in RGB colors.

My best guess is that your monitor is starting to go, just from that picture. What are the specs on the laptop?

Intel Core i3 and nVidia 920M 2 GB, 4 GB ram. Other specs that I should mention?

no that's fine. just needed to find out if you had a dedicated graphics chip, which you do.

So it's either the monitor is starting to go (relatively easy fix compared to the following) or your GPU is starting to fail (pretty much calls for a new laptop).

If you can, use a cable like HDMI or VGA to connect your laptop to a tv/monitor. that'll narrow down the problem

Will try to connect it to other monitor, but can't do this today. If everything looks fine on the other monitor, what the problem should be and what's the fix?

If everything looks good on the monitor you plug into, then you're looking at your laptop screen being the problem. You can replace that yourself or take it somewhere to get it done. That's best case scenario.

In either case, backup everything important if you havent already
