I just recently replaced my graphics card due to it giving me black screen almost everytime I boot my PC up. Now I have a similar problem. Everytime I play a game it works fine until 30 minutes or so. It suddenly says no signal (I use DP to Mini DP). I need to manually restart or shut down the PC and everything works fine again. So far I'm having this problem when I was playing Dying Light and CSGO. At first I thought it was the driver so I tried to uninstall the old one (Used DDU) and clean install the new one but that didn't help at all. What kind of test should I run ?
P.S they replaced my old GPU with a new one.

System Specs:

i5-6600k
ASUS GTX970
ASUS Z170 Pro Gaming
Corsair LPX 16GB RAM
Corsair RM750i

that usually happens due to overheating ..monitor your temperatures first with something like hardware monitor to eliminate that factor. if it gets too hot its propably heat issues, clean the dust from the cpus heatsink and fan reaply thermal paste and make sure the heatsink locks correctly on the mobo

My temperature on the GPU goes to 60 Degrees Celcius before it suddenly gave me black screen. and I was only in the game for like 2-4 minutes. My PC is just 2 months old and I don't really see a huge dust build up that may cause the overheat.
(EDIT) It only happens when I'm playing my games. When I run furmark there is no black screen.

I started getting this black screen issue from yesterday (April 18th), so far it has happened twice. First time was when playing Crysis 2 and second time when playing Titalnfall. The temps were around 70C. After 5 minutes of playing the screen went black and GPU fan speed had accelerated. The monitor power light was just blinking and the computer didn't shut itself down either so I did it manually. After rebooting everything was fine.

Mine is also fine after rebooting the problem is when I start playing games again and the screen just go black again and I need to shut it down manually. The black screens only happen when I am playing my games.

cpu temps cause that kind of shoutdowns, not gpu, when i was a kid and didnt love my pc more than my wife, i had the same problem cause the spu heatsink was too dirty and it has hapened to me later on life when a cpu heatsink had a bad clip and didnt contact well with the cpu

Use MSI Afterburner. You can choose to monitor whatever temperature you want.

I dont think its my CPU because when im on onboard graphics it runs just fine so it might be the GPU that is faulty anyways I already returned it and I will update u soon
