Z170 Extreme7+ not rebooting

I recently purchased this motherboard:

https://www.amazon.com/gp/product/B012D7GV78/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1

I installed an i7-6700k processor, a Noctua NH-D15 heatsink and fans, and 2 Corsair LPX 2x16gb memory sticks.  I get the system to boot fine and installed windows with no issues.  The Rest of the system are parts from my previous system (Corsair HX850W PSU and an EVGA 960 video card in an Antec 1200 case for example).  Problem I have is if I shut it down, soft reboot, or hit the reset button the system powers up but I get no post.  I have to turn off the PSU switch to cut all power to the board before I turn it back on and hit the power button then it powers up and posts/boots fine.  I've tried the video cable into both the motherboard without the video card installed or into either with the video card installed to try to eliminate any variables.  All the old parts worked fine before upgrading the system.

When I try to reboot or start it up and it doesn't post the code on the board gets stuck at 55.  Any idea what could be causing this?  Would a bios update fix the problem?  Is this a known issue with this board?  Would really hate to have to disassemble it all and RMA it or return it if its something I can fix.  Very aggravating issue that while I can work around I really don't want to have to.

re: 55

Which mem slots is the mem residing in?

At work so I apologize for lack of information. I'm running Windows 10, the ram is in the furthest left and 3rd from left slots, and the type of ram is 3200mhz lpx:

Corsair LPX 32GB 2 x 16GB Memory https://www.amazon.com/dp/B016ORTNI2/ref=cm_sw_r_cp_apa_iwDuyb0N86MYM

I purchased 2 more sticks so I'll be populating all the slots once I install the other 2. I've tried setting the ram to default setting and to the 3200mhz setting but haven't tried much else as it seemed to be working properly since it would post and run in the scenario I described. I'll try out the suggestions and look more into that when I get home. I'll also check the approved list once I get home and can double check the specific model number on the packaging of the ram.

Thank you for the help everyone.

Yea, shoot 'em an email through Tech Support and inquire of compatibility.

Keep us posted when they reply please.

Yeah they are in A1 and B1.  Too tired tonight.  Will test out some of the suggestions in the next few days.  12 hour days and an hour commute drain the energy out of me.
