I've been struggling with a frustrating issue where my PC randomly reboots after about an hour of gaming. I built this PC myself last August and have tried everything I can think of for the past eight months. Here are my specs: MSI PRO B650-s wifi motherboard, AMD Ryzen 5 7600X CPU, NVIDIA GeForce RTX 4070 GPU, 32GB of Corsair DDR5 RAM, an Endorfy Fera 5 cooler, a 2TB Apacer storage drive, and a GIGABYTE P750GM power supply.
The strange thing is that it doesn't reboot during stress tests, and I've taken it to two repair shops, both of which found no issues. It seems temperature-related since adding a fan or taking off the side panel extends the time before reboots, but I haven't recorded any high temperatures right before the reboots. The CPU did hit 95 degrees during stress testing, but I've read that's acceptable for AMD processors. Any advice or thoughts on what could be causing this would be appreciated!

Hitting 95 degrees is definitely on the edge for your CPU. It’s important to check the thermal paste on your cooler. Here’s what you should do: remove the cooler, check the thermal paste spread, ensure you took off the protective plastic from the cooler’s bottom, clean off the old thermal paste, then apply new paste and reattach the cooler. If that doesn’t help, consider upgrading to a better cooler like the Thermalright Phantom Spirit.
95C is kinda expected for a single-tower cooler under stress tests. It's likely throttling, but usually, that doesn’t cause reboots unless there's a major overheating issue. I’d be cautious about your power supply; it might be overheating or defective.
