PC crashes about 30 seconds into running a game

[oldskoorebel]

About 6 months ago I bought a pre-built PC. Everything on the PC was working as expected. But recently I decided to move the parts into a new case because I wanted more space for hard drives. This required me to purchase a new Motherboard, power supply & CPU fan.

After building the PC, I've run into an issue. I can use the PC for hours on end while running intensive tasks like music production, video editing, watching 4k video, etc. But for some reason whenever I run a game, it crashes a couple of seconds into the game. Even if I'm only in a menu. When It does crash I get these weird little blue or red squares on my screen and it usually requires a reboot. I've gotten a blue screen once before, but usually the PC just freezes. I've tried several different games, and I always get similar results. Sometimes the game crashes at a particular point. For example, Far Cry 5 always crashes once I reach the top of a particular ladder.

Something to note: The prebuilt PC came with SODIMM ram, so I have to use a SODIMM to DIMM adapter on my new motherboard.


Part list:
MB: Z270 Killer SLI/ac
GPU: Nvidia GTX 1070
CPU: Intel i7 6700
PSU: EVGA SuperNOVA 750 G2
RAM: 2X HYNIX 8GB DDR4 HMA41GS6AFR8N-TF


Solutions I've tried:

Uninstalling and reinstalling graphics drivers

Making sure my motherboard isn't overclocking anything

Disabling unused sound devices

Checking temperatures during a crash; Nothing seems high enough to warrant a crash. Plus it always crashes a couple of seconds into a game and I wouldn't think that would be enough time for the temps to get high enough to overheat.


If I had just build the PC, I would have assumed that I had a faulty GPU. But since it worked just fine in the prebuilt, I'm not so sure. Any help would be appreciated.

The error message is typically associated with a driver issue. Very strange, if you've uninstalled/reinstalled.

Did you manually uninstall? Or use something like DDU?
If the former, perhaps try DDU - you may have overlooked some part of the driver files.

I just tried using DDU to uninstall my drivers, reinstalling the latest NVIDIA driver then playing Battlefield 1. Same issue with the squares on my screen, but this time I managed to get a different error.

I wasn't installing drivers while I was playing, and I certainly wasn't removing my graphics card. Any ideas?

Which 1070 do you have?

Which 1070 do you have?

Here's what CPU-Z says

Weird thing is, I don't really know for sure what model it exactly is. I got the card from the prebuilt, and I can't find any information as to what card comes with that model of PC. I pulled the card out and googled the number on the back of the card's board, and it pointed to this card
https://www.asus.com/us/Graphics-Cards/TURBO-GTX1070-8G/
But the plastic case around all the pictures of the card look different than the one that I have. Let me know if there's anything else I can do to check

I think I figured it out. I noticed that my PC crashed whenever my temps reached around 70. This isn't high enough for it to be an issue, so figured it wasn't the problem. But after doing some research I found some posts with similar problems that suggested that it might be a power issue. I'm guessing when the GPU reaches that temperature, the GPU requests more power than the PSU can handle, so it crashes. So, I downloaded GPU Tweak II and turned my power target from 100 to 80 percent. For now, my PC plays games with no crashes. So I guess either my PSU is bad, or I just need a more powerful one.
