What happened to the screen on my HP Probook 6555b laptop?

Question

Computers

There are two more screen fragments, but I reduced them and still do not fit for publication. But the essence is this, for no reason at all, the screen starts to be covered with strokes, the outlines of the graphics disappear, and after a few minutes of such a carousel, the screen turns black, and then completely turns off for a reboot. Now I am writing from him and it seems to be normal now, but in the morning when he is still cold, everything repeats.

The video card dies - most likely a replacement. You yourself are unlikely to do this without experience and a soldering station.
Evaluate the feasibility of repair by finding out the replacement price in a normal service
