Crosshair x670e extreme powering off and locking up after 30-60 seconds

Level 7

Hi, I upgraded from bios 0805 to 1410 via the easy to flash tool yesterday. It was working fine for a few hours but when I got back to my machine today I found it with the power light on, the internal LEDs on, fans off, and everything unresponsive until I turned the PSU off and on. After a power cycle it will work for about 30-60 seconds before hanging in the same way. It will hang if it is in UEFI or booted into Windows 11.

I have tried downgrading the bios to 1202 and later 1003 via bios flashback with the same results. It will flash, I can get into UEFI and see that the version is the one I flashed, but it will lock up after a few moments as described above.

It was mostly stable before the bios upgrade, any input is appreciated.

Does the system exhibit this behaviour directly after clearing the UEFI? e.g. no DOCP or any alterations in BIOS.

I have cleared the settings with the rear button and by the load defaults button in UEFI.
