Computer won't boot unless MemOK is pressed/ Overclocking fails

I just built a new computer. If it the first time booting after being unplugged, after the splash screen, it will say overclocking failed and then let me go the the bios and boot from there. If it is not the first time after being unplugged then during post the cpu light act normally then the memory light flashes for just a moment and then just sets there like it is going to boot but nothing happens, if I press the MemOK button any time during post or after the memory light flashes it will restart, go through post, and after the splash screen it say the memory is ok and lets me go the bios and boot from there. That is the only way I can get it to boot.

The things I have tried:
switching to different memory
switching memory slots
using only one memory stick
removing the video card
unplugging and re-plugging everything
turned on XMP
turned off XMP
possibly others that I don't remember at this time

Here is my setup:
MotherBoard - ASUS Z87-PLUS LGA 1150 Intel Z87
CPU - Intel Core i7-4770K Haswell Quad-Core 3.5GHz LGA 1150 84W
HDD - Seagate Barracuda ST1000DM003 1TB 7200 RPM 64MB Cache
VideoCard - MSI N660 TF 2GD5/OC GeForce GTX 660
Case - Rosewill CHALLENGER Black Gaming ATX Mid Tower Computer Case
PSU - Cooler Master i700 - 700W
Memory(1st) - G.SKILL Ares Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900) Desktop Memory Model F3-1866C10D-16GAB
Memory(2nd) - HyperX 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model KHX16C9K2/16

PS - I am not overclocking and i am using the default setting in the bios, so when it says overclocking failure I assume that it has to be talking about the built-in turbo overclocking?

Any help will be greatly appreciated.
Thanks

    You can get to BIOS (sounds like you mentioned XMP), if so make sure you have the latest BIOS...if so reset the CMOS and try with a single stick of DRAM in slot 1 closest to the CPU...If no joy may want to try a different PSU if available or if you can borrow one, else think I would bench it, have a guide that might help here:
