Your hot spot isn't getting too hot while the core runs at 70 degrees. That's a big gap that usually means there are thermal coupling problems and it probably needs repasting. I'm not saying this causes your problem, but your card is definitely struggling right now.

Hey new guy! What's up? 1| A driver problem 2| Your computer system is corrupted 3| The GPU is getting too hot 4| A mismatch between your refresh rate and the drivers/software/monitor/GPU I recently bought a new CPU, motherboard, and RAM for my 64 GB 9950x3d build. Did you reinstall Windows after switching hardware? Check if the BIOS version matches yours on the board. I also have two systems running at once (Windows). I tested different driver versions—576.15 is the latest and 560.70 is the oldest. Maybe try using DDU to wipe all GPU drivers in Safe Mode, then reinstall them manually with version 566.36 by right-clicking the installer and choosing Run as Administrator to see if things get better. For Windows, grab a spare hard drive, put one copy of Windows on it offline, install all necessary drivers, and check if the problem is still there. Dual-boot setups often make weird surprises happen sometimes.

Not right away, but I've already done a full Windows reinstall recently just to be safe. I'm using version 3.20, which is the newest one available. Let's give it a try and see if that solves the problem. Not sure if this could cause any other issues, but yes, my Windows is completely on a separate 1TB SSD while my main Linux drive is somewhere else. I think they share the same EFI partitions, though not sure if that might hurt things. I'm kind of curious if it's related to my motherboard too, since this exact problem also happens with my older graphics card? Current problems with an ASRock board and a 9800X3D processor aside, I wonder if, even after reseating the cards many times, my PCIe slot might be damaged?

Your hotspot shouldn't get hotter than 120 degrees while the core is running at 70 degrees. That's a 50-degree gap, which is much bigger than usual. This probably means there are some thermal connection problems and you might need to repaste the card. I'm not saying this is why your problem started, but your card is likely having trouble right now.

Therm is the only thing that's not a normal thing, so you should be careful of it. You are right about reusing things again.

I'm going to try a new paste just to see if it helps with heat. I don't think it's unlikely if it shuts down on its own to save things, though it feels strange for such an old card to break so easily.

The process for making these dies has gotten better, but not really the factory. The machines are still getting tighter, which means they need less heat and it is now trickier to keep everything hot enough. It is more usual nowadays to put a new layer over an old one when working on GPUs from around the 20 series onward.

Alright, it's been a few days now, and things seem much cooler because I changed my power supply setup (I used PTM instead), so there are no more black screens or freezes since. I'm also probably going to try undervolting, because I've heard that the 4090 can run at lower voltages without losing too much performance while using less heat. Thanks everyone!
