I've had this PC for about 7 years now, and it's been shutting down on its own fairly often during that time. The only temporary solution I've found is to mess with the 24-pin power cable. When it shuts down, the PC seems partially on—like the RAM lights are still glowing, but the fans aren't lit up, and nothing appears on the screen. I first built this system in 2018 and was concerned that the 24-pin cable wasn't seated properly, but I didn't think much of it. I've tried unplugging and re-plugging the cable, but it doesn't stick as a lasting fix. Has anyone experienced this issue, and what solutions have worked for you?

Have you replaced the PSU or motherboard at all? If not, it might be time to look into that. It could also be a connection issue; check your power supply's 24-pin connector and see if it properly clicks into place. If it feels loose, that could be your culprit!
The problem could be as simple as loose cables or overheating. If it’s overheating, though, it would likely shut down more frequently. Changing out the power supply might resolve your issue and is definitely worth a shot!
It sounds like you might need a new power supply or motherboard. Those connectors can sometimes get warped or worn out, which can mess with the connection. Take a close look at both parts to see if there's any visible damage. If the 24-pin isn't clicking in correctly, that's a red flag.
Have you considered just replacing the 24-pin cable? Sometimes the cable can start to fail over time.
I haven't replaced either part since I built the PC. I also recently moved several times, so I don't think it’s an external issue. And yeah, I heard it click when I plugged it back in, but it's not staying secure.
