PC crashes with colored squares

[//ascension]

So for the third time in about as many days, my PC crashed. It was the same way each time, with the image on screen freezing but superimposed are these flickering squares. The color of the squares seems to be dependent on what color is on screen. The first two times it happened MGS:V was open so I first assumed it was an issue with the game, but it just now happened again with nothing open but Chrome, BitDefender, ND a few other things. Is this an issue with my GPU? Or do I just need to do a software fix? Thanks.

I attached some photos of the crashes, but I forgot to take a photo of the lost recent one.

Are you overclocking? This has happened to me, but only when I was OCing more than I should have been.

1. if you are overclocking your gpu tone it down

2. if your not RMA

I am, but this will change first thing in the morning. I'll try going back to stock speeds, see if that makes a difference. I will report back in 7-8 hours.

Your gpu is dying. Time for a new graphic card. Turn to stock speed and run furmark or occt gpu test. Your gpu will probably get artifacts within a few seconds of testing.

Your GPU it's on its last days.

That or you went a little overkill with the overclock.

He has a 980 from what his profile says, Id hope that this is just an OC gone too far considering the 980 isnt an old card.

Reseat the card.

Test 

Turn off your OC.

Test

RMA if you still can

Replace!

Still, in electronics being new doesn't mean it will not fail soon.

This is tru.

I guess we needa wait to see if resetting clockspeeds does the trick

I like your response quick and strait to the point!!!

Anyone know a good free GPU stress test that won't overstrain it? 

 

EDIT: about how long do you think I should run Furmark for? It's been going for a few minutes now with no issues.

Unigine Heaven / Unigine Valley / Furmark (is on the stressier side)

OK SO: Furmark has been running for about 20 minutes, and everything's fine. I am in fact typing this on the very PC that's been giving me issues. Power has been sticking around 99%, temperature at 75, GPU usage at 99%, and, most importantly, no artifacts. So unless someone says otherwise in the next half hour or so, I'm going to call this issue solved.
