I rebuilt my pc with completley fresh new parts that were RMA'd from msi. The computer would turn on but would be stuck at post code 2b and nothing else would happen no display anything. I really dont know what that code is or what to do. Before i rebuilt my pc something happened causing the computer to shut off and when i would try to turn it back on it would startup and then shut down. I did a power supply test and it came back green on corsairs ax860i. Please help i dont know what to do.
