Windows 10: pc and games frezzing monitor & gpu

"When I play a game, for example, like League of Legends LOL, after about half an hour of playing, the screen turns off, the game freezes, and my computer also becomes unresponsive. I can't even use Win + Ctrl + Shift + B to restart the graphics card. Afterward, everything seems fine, but the game completely shuts down, and applications like Discord are affected as well. My computer drivers are all up to date, temperatures are low, and everything seems fine."

Gaming Laptop uses dedicated GPU on a non-existent monitor

So I have a bit of a complicated problem. Up until recently, I've been doing good with my Laptop. It has an igpu and a dedicated gpu. I had 2 monitors, the one directly connected to my laptop was run by the igpu, and the external was run by the dedicated
gpu. I am on vacation, and don't have access to my second monitor, and now, when I try to run a game with my dedicated graphics card, it will try to pull up the game, but close it, since the dedicated gpu is set to my second monitor. How do I change this?
My Geforce Experience app isn't working by the way.

 

Windows update: one PCIe slot and one GPU kaput

Memtest86 is good, but no RAM tester can detect all possible RAM failures. I would suggest that you adopt a slow and careful step-by-step approach to troubleshooting this clear hardware issue. I would suggest that you strip the PC to the bare minimum. Unplug all external devices except monitor, mouse, and keyboard. You've already removed the GPU, so remove all but one RAM stick (and try other RAM sticks too). Remove unnecessary PCIe cards (extra USB ports cards, WiFi cards, for example). If it fails in as stripped-down version as you can achieve then I'd look at the PSU, and then the motherboard. This isn't a software issue though.

 

GPU intensive RTS?

This list is great. Now I got some buying to do, but please keep them coming. I love games that make me step my PC up.
