Omen 15-ce011dx crashing when playing games.

[SpaceCucumber]

For a while now whenever I try to play games such as Space Engineers, Rust, SCP: Secret Laboratory, and Kerbal Space Program, the computer will crash, it will not blue screen or anything of the sort, the screen will just turn to black. This has even occurred with Photoshop. I have updated everything from my HPET Driver to the latest Windows 10, double and triple checking everything. I've gone through omen support to send in my computer in and have it repaired countless times.
Here's all of the things I have had replaced on this machine, by hp;
CPU; GPU; Motherboard; HDD; Keyboard; Track Pad; RAM; Fans; Heatsinks; and Thermal Paste.
The only thing that I have changed to this computer is I added a 16 gb stick of ddr4 ram that was the same speed as the 8 gb stick provided. Both HP and I are stumped and I have no idea what to do. This has been going on since around January.

The most mysterious part of this is that from 6/7/19 to 6/10/19 the machine was not having these issues until I rebooted it late evening on 6/10. 
I am open to all suggestions but at this point I'm willing to just throw this thing into the trash and buy a new PC, as this has been infuriating me for months.
