Power supply unit completely disconnected.
Power supply unit completely disconnected.
I have a concern and suspect I already understand the solution, but I don’t have the funds right now. So it might have to wait. Everything seems okay until power cuts out suddenly. After shutdown, it fails quickly before Windows loads. I experienced a GPU power socket issue with my 4080 earlier. A repair person fixed it using a cable modulator. I thought that could be the cause. They removed it, cleaned it, and it worked for a while—about a week. Then it failed again. I noticed a big temperature difference between the GPU and the hotspot. I cleaned it out, but it didn’t last. I changed the paste, but it still doesn’t boot properly and shuts down. I removed it from consideration and encountered endless memory training loops. Because I bought four dimming units without understanding how they work on an AM5 board, I swapped them out. That didn’t help. Returning the GPU fixed the issue temporarily, but it still powers off before Windows loads. I don’t have another CPU, board, or PSU to replace parts. I’m planning to take it somewhere with proper tools to check for bad components. One thing to note is this happened before. The first time I cleaned the GPU, it worked for a week. Then I checked the CPU paste to rule out liquid metal leaks. I had a frame and gasket installed, so it was okay temporarily. About a week later it failed again. I left it to rest for roughly 24 hours without trying anything else, and it came back. Around that time it reached the shutdown point I’m facing now. It’s been about two more days, so I’ll wait to see what happens. If I can’t fix it myself, what should I do next? The 7950x 64GB is still at 6400 MHz on the 4080 Auros master 1000W EVGA plate, around two years old.
You've encountered a problem with the graphics card melting before; double-check the connectors on both the card and the power supply side. Are there any error messages or light signals from the motherboard when it won't start up?
I've received the latest bios updates. I'm getting drama led and 15 training marks. Cablemod provided me with a new cable as part of the issues that occurred. It's a 4-pcie to 12v high power cable, quite thick—hard to bend. The cable itself is fine. I suspect it will function properly unless things keep going like this. If it continues this way, it won't last long before shutting down again. By shut down means a sudden power cut. I didn't realize I was only training one dimm; I'll check soon. It's been stable for two years, so a faulty device seems unlikely. The PSU exceeds my requirements, suggesting it hasn't been stressed much.
I've received an update. Feel free to call me silly if you wish, but I appreciate the appearance. As long as it doesn’t cause lasting harm, I’ll keep this setup. After the final patch while playing RDR2 on my laptop linked to a TV with an MX450, it really looks rough. I’m not convinced it’s hardware. Then it occurred to me—since I’ve done a lot of custom wiring during assembly, I went back and removed connections. Shortly after, the MB would cease displaying debug messages following failed memory training. I also spotted a faulty fan. Checking the MB info, it usually points to an incorrect connection at the 24 pin. That’s likely where you’ll see me called a moron. I have two 90-degree RGB adapters to conceal the wiring. I swapped them out, and voilà—immediately relieved. It took a while after training for a black screen to appear, but eventually it worked. The system booted and stayed logged in for at least half an hour while I finished a video. Now all that remains is reinserting some cables in the back and swapping the second dimmer switch. I’m confident this gets me back to enjoying RDR2 as intended. Thanks for your help. Even though it wasn’t perfect, you helped guide me toward the solution. Have a great night! Thanks again.
