Hi guys,

I made this build a couple weeks ago and it's been treating me well, however, yesterday I tested editing in Premiere and ever since I've been getting some weird artifacts in every game I launch (examples below) They come in the form of weird squares and rectangles.

I've tried clean driver reinstallation for my GPU and some hardware reinstallation just to make sure nothing was loose but it was to no avail.

Could this mean my new GPU is faulty? Or does this look more like a Power Supply issue?

Thanks

Did you use the DDU tool when you reinstalled the drivers?

If not, run the DDU tool in safe mode to remove the existing drivers and try again.

Are you overclocking? If so, what happens when you bring the card back to stock clocks?

No Overclocking. I'm using all the components as they first arrived with the latest drivers. I'll try a fresh install with the DDU tool.

UPDATE: I fresh-installed the latest Geforce drivers after using the DDU tool, but the artifacting is still there.

What's the manufacturer/model name of that Geforce GTX 1080 ? Factory OC model?
What GPU temperatures are you getting during gaming session?

GIGABYTE GeForce GTX 1080 DirectX 12 GV-N1080WF3OC-8GD 8GB 256-Bit GDD

Gaming sessions in Stalker at max settings are getting me about 55C on average with some spikes to 70C here and there.

GV-N1080WF3OC-8GD is overclocked model:

• Boost: 1797 MHz / Base: 1657 MHz in OC mode
  Boost: 1771 MHz / Base: 1632 MHz in Gaming mode

Downclock to Nvidia reference clocks 1607mhz base/1733mhz boost.

How would I go about doing this? In MSI or in BIOS?

Use MSI Afterburner.

Use MSI Afterburner.

The problem persists. Only when gaming and sometimes during the menus of Geforce Experience... I think I may RMA if I can't find any fix.
