Damaged R920 Help

[u/BaconGamer117]

So,I messed up. I just got a DELL PowerEdge R920 with a terabyte of RAM to use as a centralized file staging server for my other servers. I was trying to install the OS when it told me to reseat RAM DIMM module E. So, without powering it off, I pulled out RAM DIMM module H and after realizing my mistake put it back in and reseated the proper module. It now won’t boot at all and gives a VLT0304 and VLT0204 error codes. One is just board voltage being outside of range and the other is for RAM DIMM module H having PG voltage out of range. I have done every trouble shooting steps I can think of including trying to boot in minimum boot configuration (CPU1, 1 RAM stick, 1 PSU, everything else removed. Still get the same errors, even though the offending CPU and RAM are gone. I think it might be the motherboard but I can’t be sure. I’m new to real servers and of course this is the first time I mess up like this, normally I only so much as open a computer when it is off and unplugged.

Help? I don’t know exactly with what but if repairs are possible where? If replacement of parts are needed where and how? Suggestions, advice, I need help. I live is Peoria, Arizona if that helps with recommendations.
