GPU Cuts in and out on Linux

[CWALD]

Hello, first post on here so let me know if I mess it up.

I am currently putting together a small form factor scrapyard PC for LTX 2020 BYOC. At this point I am running an i5-4570 and a GTX 1050 2GB with POP OS!

 

My problem is that whenever I try to run something that goes beyond bare minimum GPU usage, I will start to get an occasional blackout (screen goes blank) for 1-2 seconds before everything returns to normal. CS:GO on medium settings is about where I start to see this behavior, games that hardly use the GPU such as Star Craft 2 run fine.

 

My thought at this point is that my Craigslist GPU is either bad or overheating. I am going to try installing GPU monitoring software tonight and maybe replace the TIM and/or under clock it this weekend. but I was wondering if you guys had any other ideas as I don't really want to under clock a GTX 1050.

 

Thanks in advance!

Did you install the nvidia drivers?

I am using the Nvidia version of POP OS, so my understanding is that it should already have them and that they should have automatically updated when I updated everything else. but I have not verified any of this.

type

inxi -G

in the terminal to check your driver version

I will definitely do that first. Thank you!

Quick update: My driver is up to date and my temps look good after returning to the desktop from about 30min of 7d2d on the medium preset. I'm still going to install monitoring software and do a stress test just to see if it reveals something but I'm not sure what else I can check.
