Games on new PC keep freezing and crashing to a black screen saying there's no HDMI signal.

[CLH2012]

I have a frustrating situation. Every time I try to play any game on my PC I can play for close to 20 minutes or so and then the game just freezes, goes to a black screen, and says no HDMI signal. My PC is brand new, I just built it and I'm wondering if it has something to do with the GPU. It could possibly be a cooling problem, but I can't tell for sure. My PC does not overheat, freeze, or crash when I am browsing the internet and as far as I can tell it doesn't overheat when I play games, it only freezes and crashes and goes to a black screen. I have an HDMI cable hooked up to my graphics card and that goes to the monitor. I really can't pinpoint the problem because I'm new to PC building and this only happens when I play a game. If anyone has an answer to the problem or can offer some assistance it would be much appreciated.

PC Parts:
Case - Commander G42 Thermaltake
Graphics Card - NVIDIA Geforce gtx 660
CPU - Intel Core i7 4790k LGA1150
Motherboard - Gigabyte GA-X97X-Gaming 3
SSD - Samsung SSD 850 EVO
Power Supply - Corsair CX750
Operating System - Windows 10 Home 64 bit
Monitor - AOC 1080p 23"

I also have a D-Link wireless dual band PCI express adapter to get internet, which can connect fine with no problems and I have 8GB of RAM.

I have already tried swapping monitors and HDMI cables and that did not work.

Update: It just crashed when I was on my desktop with the same problem.

My first instinct is the gpu. Can you download a program to monitor your gpu temps? I'd like to see some in game temperatures to see if the gpu is overheating. It's probably a faulty gpu if it is overheating. But first let's try this.

Download ddu and select nvidia. Select clean and shut down. Then take the gpu out of the pci slot and check for dust, reseat the card firmly, make sure all the wires are secured, etc. Then boot, go to nvidia's website and download a fresh set of the latest drivers and install.

If that doesn't work, then you can move on to testing ram. Run memtest. If it comes back with an error test each stick individually to see which one, or if both are causing the problems.

Lastly, it's probably the power supply if all of the above failed. I imagine the error you're getting is kernel event power 41 or display driver has stopped responding right?

Either way if you go through all of the solutions above, I'd first try to replace the gpu (if one of the above solutions doesn't solve the problem) If it continues to do it then it's the psu. So I'd replace that next. Probably with an evga one.
