Just put my first build together today and I had a successful test boot outside of the case but noticed the start up was only recognizing half of (8gb) of the memory, so I switched them around and made sure they were really seated correctly. I assembled the rest inside the case and everything appeared to be working correctly but it was not booting. Took the RAM out and re installed and I'm now getting a 55 on the Q code. I've tried everything, switching the configuration, resetting the BIOS, booting with one stick of RAM and it's still stuck on that 55. I even tried different RAM (brand new) in it and it's still staying no memory. Is it possible for the DIMM slots to break or something? Running out of ideas here and I've googled everything.
