PC restarting on its own in low resolution.

[woodypride]

New PC built 2 months ago:

-I7 9700k

-Asus ROG Strix 2080 Super

-Gigabyte Z390 UD

 

A week ago my PC began to occasionally restart on its own. When it turned back on the main display (Omen X 25f 1080 @240hz) would be in a much lower resolution, sometimes 1024x768,  sometimes 800x600. My secondary display (Samsung 1080 @ 60hz) doesn't display anything at all. I can't change the resolution at all and it won't detect the second monitor. I updated drivers and it seemed fine for a couple days but now the problem happens more frequently. All components are brand new.

 

Am I unlucky and have a bad GPU or could it be something else?

Use DDU(Display Driver Uninstaller) to completely uninstall all graphics drivers and files, then after it is done re-install the GPU drivers using Geforce Experience. I would also take the time to make sure all other drivers and your bios are up to date, make sure you are getting them from the motherboards support page on the manufacturer website and not using Device Manager or Windows Updates as they are generally out of date or not even the right drivers if you get them from there.

It's in 1080 now but it's super blurry now and there's horizontal pink lines across the monitor. I'm not sure I can navigate to find a DDU. It doesn't represent just how blurry it is very well but I've attached a picture from my phone. Second monitor is HDMI only and I can't detect it through either HDMI port on my GPU.

That is called artifacting, and it's not a good sign. If DDU and fresh drivers don't work it means the GPU is bad and you will have to RMA it, you could also see if it still returnable through the retailer you purchased it from.

That's what I was afraid of. I've barely had it 2 months but it looks like I just got unlucky. Thanks for your help.
