BL465 Gen8 Stuck in BIOS Loop - Not Posting

[InTech2000]

Hi,

We have a BL465 Gen8 Stuck in BIOS Loop.

It starts to boot gets to" Early System Initialization 10%" , then 40% then restarts back to 10% and keeps looping.

A couple of times it has completed post and succesfully booted to the OS, then the server just reboots shortly after.

I have installed the latest firmware :

iLO 4 - v2.73 - 11th Feb 2020

BIOS - A26 03/14/20018 

Power Management Controller Firmware - 3.3

OBA Firmware is v4.90 - 11th Dec 2018

The only thing the iLO IML says "Maintenance note: CPU(s) operating at reduced performance level due to an enclosure power event."

However, the power levels seems fine in the enclosure and no other blades are affected.

The server is in a DC on the otherside of the world, so any remote stuff I can try first would useful.

Appreciate any help.

Thanks.
