Graphics Card Problem

[Jeromaine Lopez]

Ok so last night, I was playing WoW as usual until the screen randomly turned blue for 3 secs, and then my computer did a restart. As it restarted my resolution went down to 800x600 capped, I cant change it anymore. And also blue squares in lines are appearing on the windows desktop screen. I don't know what this problem is please help 🙁. I am also getting code 43 when I see my graphics card on the device manager.

Specs:
Intel i7-4770k
EVGA Gtx 780 SC
Asus Maximus Vi Hero Motherboard
16gb corsair vengeance ram


Things I have tried
Clean factory reset
Downgrading windows 10 to windows 8.1
Moving graphics card to different PCI slot


Also, it isn't my monitor, or motherboard, or cpu as I connected my monitor to my IGPU and everything was fine.

Thanks for helpin!

For that code 43 follow these steps in video.

If the problem persist, if possible try another video card and if it works then it means that GTX 780 is probably failing. I would then contact EVGA since that GPU might still be under warranty.

EVGA: 1 (888) 880-3842

still not working, small blue squares in lines, and 800x600 still there

If possible try using a different graphics card and see if that works. When you used the onboard graphics where you able to go back to the correct resolution?

Yes I was able to go back to my 1920x1080 resolution with the IGPU. And sadly I don't have another graphics card 😛

That's fine, I would contact EVGA since it sounds like your GTX 780 is the problem. The card has a 3 year warranty.

It does sound like a possible bad GPU. What power supply do you have? If it is not a quality unit, I would definitely recommend replacing it first. Even if the card is bad, it could be bad, because you have a poor quality PSU.
