[SOLVED] Is my GPU dying? Green reflections and textures stretching

[francisco.caruso.c]

Hi, I've been experiencing some weird glitches with my GPU lately.
In Warzone, If I set textures to more than low, some weird bright green lights would flash randomly. This same thing happened a few weeks ago in The Division 2, but much worse, since all the screen was filled whit these green lights.
Also in Warzone, the textures would glitch and stretch , blocking the whole vision, the HUD and weapon are rendered just fine.
Today I've been working on Ubuntu 19 and noticed some weird pixels in a "T" shape, later I tried to reproduce some of the errors in Unigine to discard a Windows Issue. The same green lights appeared on some reflections but much dimmer, and the same texture "stretching" happened on a plant. Also I could see some of the "T" shaped pixels.
It all happened around the same (2 or 3 minutes), except for the pixels, which where there from the start.
GPU is not overheating, but its known for having bad cooling.
Sometimes (since I've bought it), a white led besides the power connector flashes, which today I've found means a power failure.
Drivers in windows and Ubuntu are up to date.

It could be a number of things...

First try reseating the card. Then, try another cable. If you're using DP, try hdmi or a different port. If all that fails, perhaps try undervolting the card.
