My rig:
GeForce GTX 970 FTW+
i5-2500k(not OC'ed)
16 GB ddr3 2400mhz
Corsair CX 750W PSU
(crappy motherboard, don't know the name)


So, I've had this problem for a little over a year now. The reason why I'm acting on it just now is because I don't know what else to do.

When I start playing high demanding games like GTA 5 or BF1, my computer shuts down with the display writing something like "There is no connection to your display", or something of this sort.

The games run perfectly normal FPS wise, no lags or stuttering. I checked the task manager while playing a game, and the CPU stays at only around 40% load. But after about 4-5 minutes into the game the computer just shuts down by itself.

The problem only started happening when I bought my new GPU, GTX 970 SSC. The CPU has a cooler so it's not overheating, I checked the temps.

What I've tried to do over the year:
-RMA gpu(got a gtx 970 FTW+ in return, still same issue)
-scan for viruses/malware
-reset Windows 7
-upgrade to Windows 10
-buy a new PSU(750W up from 500)
-upgrade from 8 to 16gb of RAM(ddr3 2400mhz)
-run several tests(CPU/GPU load, temperatures, you name it I done it)
-got the GPU hooked to my brothers PC and it had the same problem

The only thing left unchanged is my motherboard and CPU. I've recently bought the i5 4690k and Intel MSI Z97 PC Mate. I haven't tried them yet because still waiting for the CPU, but if it doesn't change anything I'm broken. Because that's it, I've tried everything in the book.

If anyone got any ideas on how to solve this, or what might be the problem, please reply.

Sadly it's not that, when I bought the GPU and started getting crashes I had 8GB of I don't even know what, they were really old. I upgraded then to 16gb. Looks like just going to have to wait till tomorrow when my CPU arrives and then rebuild the system, hopefully it'll work.
