A couples weeks ago while playing a game (Fallout 4), a checkerboard pattern of squares appearing covering the whole screen. I have two monitors, and only the one the game was playing on was affected. I assumed it was a problem with the game and simply restarted it, and it was working fine. A few days after that, I was playing a different game (I don't remember which, it might have been Black Desert Online), and the squares appeared again, but if I remember correctly they went away after a minute or two.
I continued as normal without much incident until last night, when the squares appeared again but were across both monitors and the computer crashed (froze, would not respond until I manually restarted it). I tried restarting, but it crashed again, so I decided to leave it off and try updating the drivers in the morning. I did so, but when I went to play a game the squares reappeared and the computer crashed once again. I downloaded a program to keep track of GPU temperature to see if overheating was the issue. Before I even got to the point of launching a game, it crashed while I was simply browsing the internet. This time, the pattern that appeared looked different, however.

The patterns that were appearing before weren't any particular color, it was like the image it was supposed to be displaying but with squares of distorted colors, like looking through frosted glass. A couple of times while dealing with restarting the computer, a checkerboard pattern of green squares appeared during the boot process for a split second before disappearing, however.
I have it booted now in safe mode to make this post, and there haven't been any issues so far. I hope somebody has a clue what might be causing this and how I can fix it. Preferably some way that doesn't require spending any money as I have none to spend.
 
That artifacting is normally caused by the GPU running at too high of a frequency OR by insufficient GPU core voltage.

Is your GPU running at stock clocks? Have you modified the clock speeds or voltages in your graphics software or MSI Afterburner?
 


It should all be stock. My power supply is 850W.
 

How old is the GPU? You should test it in another system if you can but it might be pooched.

EDIT: Did anything precede this? A hardware change, driver update, anything?
 


I got the GPU in November 2015. The last change I made at all was in May, when I reinstalled Windows. I could try testing it in my brother's computer.
