PC/GPU Crash - "No Signal"

[ChickenWizard]

Hey everyone, so ever since I got my Acer XG270HU (months ago), I have had a strange reoccurring issue. Whenever I change my resolution, specifically in CSGO (from 1080p to 1440p), my screen goes black and says "no signal" and my computer crashes. The audio just cuts off and I can't do anything but hold the power button and cold boot the computer. Its happened so many times I can't even count anymore, and I have no idea why this happens, or how I can fix it. It also just started happening whenever I try to launch the BF1 beta.

Does the system run fine outside of games on the 1440 resolution? Need video card model and power supply brand and model. If you run the games in 1080 resolution there are no issues?

The system runs just fine outside of games, and works fine in 90% of games at 1440p. I have a 970 G1 Gaming and an EVGA Supernova G2 750W PSU. Both work great. I will test BF1 at 1080p and see if it still crashes.

If it only crashes in certain games, you may want to check for any patches to the game or the driver. CS GO is on an older engine, it may not like running at 1440.

That's what I was thinking about CSGO, most people play at 1080p or lower (and have for a long time), so source engine must not like anything higher. And I'm assuming it's crashing in the BF1 beta because, well it's a beta (an EA beta mind you lol).
