Question Is it possible to fix GPU (Without OVEN Trick)

[MVStudio]

Hi all, I had Sapphire Radeon HD 6870 its 9 years old but from yesterday while I was rendering a video in Adobe After Effects in Element 3D, suddenly my monitor went black and again it went back to display but the screen was splited like it was connected to the second display hard to explain this, then it became very very slow, and the program crashed (after effects), then when I turned on the PC today morning it's not showing any display the screen was totally black but after some RnD and troubleshooting it was showing distorted and pixelated graphics in blue and white, now I am using the pc without GPU (on Motherboards Internal GPU).
Here is the Picture of the Distorted and Pixelated Display:

Please don't tell me to put the GPU in the oven as I don't have any Oven. The thumbnail was the image of actual what it looks like.

what I did in my Troubleshooting:
I dismantle everything then I cleaned the GPU and re-installed it.
Re-set the BIOS.
Re-Set all the memory module one by one (and found no issue with the memory modules)

Putting a GPU in an oven is generally a poor idea to begin with, so Im glad you arent open to that suggestion.
Beyond what you already tried, I would have to say its probably time for a new GPU.

If you can, test the card in a different system (bring it to a friend if you can). Your 965 can handle some modern entry level cards so you should be okay to find a replacement.

Thanks for the reply all my friends have laptops, none of them have a Desktop, I am planning to buy Nvidia this time probably GTX 1660 (non-Ti) and then after few months saving going to upgrade the whole pc with AMD Ryzen 7 2700x and so on, so I know my current 965 will definitely bottleneck with the GTX1660, but how much ?

Hard to say, but since you plan to upgrade later on does it really matter?
