I've built my own gaming PC, and it's been running smoothly for years. Recently, it's started shutting down every 10 minutes. To get it running again, I have to switch off the power supply and wait for about 5 minutes. This led me to suspect it's a heating issue since it won't restart right away. I've replaced the thermal paste and checked the CPU, which doesn't exceed 80°C. After completely disassembling and reassembling the system, it lasted about 4 hours before shutting off again. I'm not sure what the root problem could be. My setup includes a Ryzen 3600, GTX 1660, a 650W PSU, and 16GB DDR4 at 3200MHz. Can anyone shed light on this?

Don’t forget to check for error logs in your BIOS. Given everything you've described, a failing PSU seems likely, but it could also be something else. Better to investigate!
Have you checked your CPU temperatures? Starting there could help! It sounds like you’re running a bit hot but not dangerously so, with a max of 80°C while under load.
It could be a faulty motherboard or aging CPU, but honestly, it's hard to tell. You might try tweaking some BIOS settings, like lowering the CPU speed or even disabling individual cores to see if it helps stabilize things.
Dust buildup could be another issue. You mentioned replacing thermal paste but didn’t mention cleaning out the dust. It can create a lot of problems, especially around fans and heatsinks.
I'd hope that replacing thermal paste would also mean cleaning up any dust! Gotta keep things clean, lol.
It sounds like your power supply might be deteriorating. Unfortunately, you can't really know for sure unless you have spare parts for testing. If it's not the PSU, overheating is another common culprit, so definitely look into that too.
I agree, overheating or a faulty PSU seem to be suspects here.
Also, keep an eye on your fan speeds and overall power usage. Software like HWInfo can give you status readings. If you're gaming, consider using an external monitor to track everything better.
You might want to check the event viewer for any clues about the unexpected shutdowns. Just Google 'Windows event viewer unexpected shutdown' for pointers on what to look for.
Yeah, my CPU temp is around 50°C while idling, which seems high, especially since that's right after booting.
