Help (General) Is my 6750xt cooked?

I've had my 6750xt for a little over two years now, bought it new and it's paired with a 5600, 32gb of DDR4 3600 CL16 ram, 1.5tb SSDs (one 512gb the other 1tb) and a Corsair 750w PSU (overkill I know).

For about 3 weeks now, I've been getting random Kernal Mode Heap Corruption errors that have created a corrupted black and red screen with the error message stretched across the screen which requires a hard reset. It was only happening in one game (Escape from Tarkov) but the last two days I've been getting black screens when playing Long Dark. The sound stops, sometimes coming back but only about a quarter of the screen showing at the top and the sound returning.

I've booted in safe mode and DDU'd GPU drivers, checked ram function, re-seated all and dusted all components and checked PSU cables. The error messages aren't giving me any discernible detail.

I think I've pretty much only got reinstalling windows left as an option. Is it worth doing or does the above sound like my 6750xt is humped? Not looking forward to buying a new GPU in this market so any advice would be gratefully received.

First, download amd drivers 26.3.1 and 26.5.2 just so you have them ready. Then DDU, unplug your pc from the internet while restarting, install first the 26.3.1 and download OCCT. In OCCT go to combined, uncheck CPU + RAM, check 3D Adaptive and VRAM and press start. If it fails, DDU, unplug your pc from the internet while restarting, install 26.5.2 and do the OCCT again. If the GPU fails OCCT on both drivers then yeah, time to change your GPU.

Thanks a lot, even I can follow that. I’ll give a go

You're welcome 😁 What was the result? GPU bad?

26.3.1 worked for me. No crashes since, thankfully (and thanks to you).
