Game's and Windows stutters and stops giving out a display signal

Hello,

So recently I have been having some issues with my PC for the last month I've been getting notifications from NZXT CAM that my GPU frequently hit's temps of up to 81°C when under 100% load e.g. when playing DiRT 4 so I just ignored it thinking it was fine but now I'm regretting that because whenever I am watching YouTube or Netflix all three monitors will go black and then I will get the "No Signal" pop-up on the monitors and then when it comes back I get like a glitch pattern kind of like the one you'll see when you overclock a GPU too much. So I've come to the conclusion that my GPU is dying and I should contact EVGA and open an RMA Request. However I just wanted to get a second opinion.

Thanks in advance,

Alex.

Yeah, it definitely sounds like you need to open an RMA with EVGA. In the future, I'd recommend using a program like MSI Afterburner or EVGA Precision X to set a custom fan curve for your card. I have SLI 1080 Ti Founders Edition cards, and they generally don't get above 74c after a few hours of gaming because I have a custom curve set. An example of a custom curve is attached below.

Ok thank you for the advice I'm going to open an RMA when I get home.
