MSI Motherboard/RAM Issues (0d error code)

[Chaos Network]

Alright so heres what happened. My pc has been running perfectly for months now. I live in minnesota where it gets cold (currently around 0F, -30 with windchill). I live in a camper at an RV park year round. I go out of town and turn my heat off while im gone for 2 days, come back pc wont post with a debug display saying 0d as the error with the ez-debug led lit up at ram. Ok so i pull both ram sticks out and same issue (i believe i had them in a2 & b2) i try switching to a1 & b1, same thing. Try a single stick: a1 i get a bunch of stuff about memory overclock not able to be applied go to bios, go to bios but can never actually make it into windows. same with b1. a2 i get the 0d error and no bost. b2 however lets me into windows where i am typing this currently. 

 

Does anyone have any suggestions?

0D is generally considered a CPU error, though it can be triggered by bad RAM settings. First thing I'd try is to take out the CPU and give it a good once over and make sure that there was no condensation buildup inside the socket that's giving you a bad RAM channel.
