what we found is there may be an issue with part of the mainboard. if we remove CPU #2 and fire it up everything works. if we just swap cpu 1 for cpu 2 id comes with the error as before. if we swap cpu 2 for cpu1 and just have the one cpu installed everything works.  so now I either need to create a vm for this server and then just recycle the damaged one or maybe try and find a new motherboard. 
we had to move a server from one building to another. when we went to fire this server back up we get the following error. Vlt0304- Cpu2 Vcore pg voltage is outside of range  reseat cpu  second error =   vlt0204 systemboard failsafe voltage is outside of range.  contact support.  on the back of the server both PS lights are green    Help
