Hi fellow experts

I just restarted my Dell EMC server r740xd today. 

However, it is now stuck at boot loop cycle during POST.

Basically when i power on the server, it goes into the POST. During the “Configuring memory” stage, the server will restart and boot up again. Resulting in the loop.

There is no error message on the server. The server was working fine before the restart without any system error. Please advise.
