My monitor stuck/PC freezes while playing games.

[aceneck]

Hey,
I have a problem with my pc.
When I'm playing csgo, I got a problem which at random moments the monitor goes off with a "No signal detected" message and goes back to normal again for several times.
After few times of that, the pc crashes completely(everytime it looks a bit different, but in general it's a solid color of some sort, no text),
Here's an example of how it looks: https://imgur.com/a/C3DLY.

If anyone can help with some solutions,
I'd be very grateful.
thanks

Does it only do it when playing games ? what about watching high resolution videos (you want to get the graphics card working)

Might be your card is not getting enough power.
