Try running an ePSA diagnostic to check for hardware errors and let me know the results.

You can try a different power supply to help identify if the problem is related to the PSU. As long as the connectors are the same you should be good to go.
If issue persists, the problem might be related to the Motherboard or CPU overheating.
I recommend you get in touch with Technical Support in your region for further assistance.
