This problem has just started on a roughly two-year-old Ryzen 5 PC. It works fine when doing normal work and will stay on all day.
When under heavy load (gaming) the screen will go into power-saving mode after five minutes or so and the PC will black screen then reboot after a few seconds.
The graphics card is an RX570 and I suspect it is that but want to eliminate the PSU (Coolermaster Bronze 550w) before I order a new one.
To eliminate the software, I tested it on another SSD running the Furmark stress test (on both) - it still crashes but only once the test is exited.
I also tried an Nvidia GTX 1050 in there which didn't crash on the Furmark test (though it doesn't have the separate power connector so it could still be PSU).
Anything else I can try to determine what it is (I don't have a spare PSU)?
