Issue with Graphic card – display turns black.
Issue with Graphic card – display turns black.
Hello everyone, I’m experiencing some unusual problems.
My system includes a Seasonic Focus GX-1000 PSU, an ASRock X670E Taichi motherboard, a G.Skill DDR5 Flare X5 with two 16GB modules at 6000 MHz, and an XFX SPEEDSTER MERC 310 AMD Radeon RX 7900 XTX. The CPU is a 7900X3D.
About three weeks ago, while family members were using my PC, I noticed the system would suddenly shut down while running Warhammer 3 in the background. At first, it seemed like a faint smell—possibly from outside, like a barbecue—but it was noticeable. After restarting, the issue persisted. During stress tests in Adrenaline, my GPU also failed.
I thought I was just unlucky and had it repaired. In the meantime, the PC ran normally using the built-in GPU, with no problems. Recently, I received a brand-new GPU and installed it. The same issues have returned: the screen goes black under load, requiring a restart. I’ve tried reinstalling drivers but haven’t succeeded. Additionally, my internet browser "Brave" is now extremely slow.
I’m unsure what’s causing this and haven’t changed any hardware in the past six months. The GPU is new, yet it seems to be problematic. My system was stable without it before, so I’m seeking advice. Any help would be greatly appreciated!
Inspect the PSU and every cable or connector connected to the components, paying close attention to the GPU.
Shut down the system, unplug it, and inspect the PSU thoroughly—do not open it unless necessary.
Check the PSU closely and the surrounding area for any unusual smells that might point to an issue.
If everything appears normal, perform some tests using a multimeter if you have one and understand how to use it.

This isn’t a complete test since the PSU isn’t under load. Any readings outside the normal range suggest a failing or outdated PSU, possibly nearing its end of life.
Replace it with another verified working unit and ensure only the original cables are used.
Also, make sure all critical data is saved to secure locations away from the affected computer.
I would swap the PSU and use only the cables that come with it. Check the system thoroughly for any damage or other issues. Regarding the reason—if everything was okay then the connector might have been faulty over time, possibly affecting the whole PSU. Or another part could be involved. For more details, search online using terms like "What causes PSU cables to melt." You’ll find many useful links and images. For example: Make sure to install a high-quality, well-rated PSU. This could have been much worse if not addressed properly.
Thanks a lot, mate, for the guidance.
I believe my mistake was the one that led to this issue. The 7900XTX has three power connectors: two main ones and a third one intended for overclockers. I connected the two main ports to the same PSU cable and the third one to another, rather than using separate cables for each of the main ports.
It was the cable linked to the two main power connectors that got damaged in the PSU socket.
After reconnecting and testing, everything is functioning properly. Still, I plan to purchase a new PSU just in case.
Appreciate your help!
