I need help, i think my R9 390 crashes my computer and produces weird artifacts.

[Sirkow]

BUILD:

GPU: Sapphire R9 390 Nitro Tri-X OC 8GB GDDR5

CPU: Intel Core i5 4460

H-DRIVE: Seagate Barracuda 1 Tera

RAM: Kingston HyperX Fury 8 Go DDR3 1866 MHz CL10

PSU: Cooler Master G750M 80PLUS Bronze Modulaire

MOBO: ASRock B85M HDS

OS: Windows 10

I noticed the problem one day out of nowhere by starting the computer, which displayed these vertical artifact-lines in the middle of the screen : https://imgur.com/a/IqO2497.

Restarted the computer about 2 times and it seemed to fix the problem. The next day i power on my computer and the same problem occurs, this time however there was one big yellow band in the middle of the screen which seemed to change color every time i restart : https://imgur.com/a/UCexxE9. Also the computer started to crash before loading to desktop.

Tried safe mode and the computer worked again but when it reaches desktop the vertical band disappears and weird horizontal artifacts take its place : https://imgur.com/a/U56k4VJ. Also any screenshot taken via the computer itself shows no artifact at all.

I then disconnected my gpu and tried launching with my mobo's integrated graphics card and everything worked perfectly without any artifact or crash. So i took the R9 390 to my brothers computer to confirm it and the same problem occured.

Here are 2 videos of the problem :

Is it as good as dead at this point or is there any chance to repair it ? i'm just looking for any advice on what to do from here knowing that it has been around 2.5 years since i bought it and the warranty is already expired. Thx in advance for any help provided.

You cannot repair it's hardware defect GPU.

Sometimes GPU have artifacts but not in all resolutions.
You might test different resolutions and bits of colors perhaps you can use it until it's completely dead.
