Backstory: My old rig powers her current setup. It uses a FX-9590, an AMD 7990, and a R9 390X with plenty of RAM. The power supply is huge because it was built around the 9590. Over time, the system began to lag noticeably, so we upgraded everything—switched the CPU, memory, and RAM for a Ryzen 3, a Killer SLAC motherboard, and faster DDR4 modules. I didn’t focus much on drivers except updating the BIOS and installing new ones. The issue started during gameplay: her PC would freeze into a black screen and then restart after a few hours. At first, I assumed it was overheating, but checking temperatures showed nothing out of the ordinary. Now it even restarts while booting up Windows. I added extra fans to test for heat, but temperatures stayed normal. The problem might be with the power supply, which is now around six or seven years old. I ran a stress test and the machine froze after 21 seconds, but CPU and GPU stayed at full capacity. Memory tests passed without issues. What could be causing this?
The issue likely stems from the power supply. It makes sense given the age of your PSU.

It seems like the problem was likely caused by a power supply failure. I’ve seen similar cases where a system stopped working and then restarted, often fixing it with a replacement power source.
This should resolve most of your problems. If you strongly disagree or need a final option, remove your graphics drivers using DDU and then install the latest versions directly from AMD. Visit the link below, download DDU, and follow the provided steps. To enter safe mode, hold Shift while clicking Restart, then select Troubleshoot → Startup Settings → Restart → F4 for Safe Mode. Make sure your AMD drivers are already downloaded, and disconnect your PC from the internet before powering it back on, so Windows won’t install an outdated driver before you replace it.
Consensus - this problem likely stemmed from a sagging GPU putting pressure on the PCIe slot, since power delivery pins are closest to the IO. Once I positioned the card nearer to the end farthest from the IO, the black screen would restart.
