As much as you don’t want boilerplate answers… It’s the solutions to the symptoms is about all we can offer.

Restarting/rebooting systems are always hard to isolate the root cause so you end up working off a list of suspect issues unless you can get diagnostics to help focus your hunting.

Given the systems age you could have a bad GPU board. The heat sink could be failing or the thermal paste is in need of refreshing on both the CPU & GPU. These are the easiest to fix.

The logic board is more suspect then the power supply in my option. Here the VRM’s are likely failing. You’ll need to get the schematics and walk through the voltage measures.
