This could be caused by overclocking or a damaged CPU.
It could also be caused by pre-installed software, in rare cases, but not in this case since you don't have pre-installed software.
If you are overclocking, revert back to stock and test the system.
Please run the CPU stress test if you're not overclocking / reverting back to stock doesn't help
Run Prime95 to stress test your CPU. Prime95 - Stress Test Your CPU - Windows 10 Forums

Note
If you're overclocking anything, please stop it and set everything back to default while troubleshooting

Warning
Your CPU temperatures will rise quickly while under this stress test. Keep a keen eye on them and abort the test if overheating occurs.
