Issue with GPU performance or functionality.
Issue with GPU performance or functionality.
My PC runs with an RX 6800XT graphics card and a Ryzen 5500 processor, and it has operated smoothly for over a year and a half. The transformer is producing some unusual sounds above 100 watts, but it might be typical. After playing Lords of the Fallen, I experienced a crash followed by a sudden black screen. Although my mouse remained functional, the display went dark. Later, using remote desktop, I confirmed Windows was still active. I performed a reset and received five beeps indicating VGA not found. The PC started up normally, but the screen stayed black. After rebooting, the GPU reappeared, though the resolution remained low at 800x600. This suggested Windows had disabled my graphics card. I resolved this by enabling it via Device Manager and reinstalling the driver. Playing again caused another black screen. I attempted a similar fix with a different Windows version, which worked well. Eventually, I moved the GPU to another PCI slot, but that didn’t help much. I considered returning the card, thinking about a fresh Windows installation. After trying it, everything functioned properly. Over time, the issue persisted—even during gameplay or while using applications like Lightroom. It sometimes triggered randomly, even without gaming. I measured the power supply rails during gaming and found them normal. My old R6850 GPU worked previously, though it was a bit dusty. When I tried to boot it up after resetting CMOS, I received the same 5-beep error. This made me doubt whether the problem was with my card or something else entirely. (Not the PSU!) Eventually, I decided to upgrade my CPU from 5500 to 7600X. I’m unsure if this would make a noticeable difference, but I’ll need to replace the motherboard, RAM, and possibly check for memory leaks in Lightroom. Seeing Windows disable the GPU again after a reset is concerning. I’d like to prove it’s defective by getting a proper diagnosis before making further changes.
Detailed specifications and PSU information are needed. GPU temperatures during gameplay likely depend on the latest drivers. You mentioned trying to reduce settings in Lords of the Fallen—consider enabling FPS caps or VSync for stability.
It seems the process happens unpredictably sometimes, not consistently. When it hasn't occurred recently, the chances drop. However, after some time without it, the likelihood increases again. I need to keep the frame rate at 90fps, which uses around 200 watts—still manageable for a 315w GPU.
The power supply doesn't always reduce energy use, what model is it?
Have you heard too much? Take a look at what I just said. Stop sharing false info and I don’t want you to keep being unaware of PSUs. Thanks.
I understand your concern, not the PSU itself but what I experienced. I had a similar problem with a black screen and GPU not found, especially in Unreal games. Benchmarks passed fine, but once I started a game, issues arose. I replaced the GPU and it worked temporarily, then the same problem returned. Eventually, I swapped the PSU—both units functioned correctly. It seems the 12V rail was unstable under certain loads at random times. You mentioned you have two PSUs; would replacing one just be a safe way to confirm?
In reality, even with a 200 W PSU that meets the recommended specs, it won’t lead to any issues. Challenge me!
I understand you mentioned it wasn't the PSU, but I don’t know what else it was. It also stopped working during a time spy test. It was more stable with less RAM clock speed—still crashing at 2400 MHz instead of 3200 MHz, but less often. If the issue was memory, I’m not sure why I didn’t see a blue screen instead of GPU problems. As you said, I upgraded to Zen 4 and it fixed the problem.
