I would suspect either bad motherboard or bad CPU. Have you or can you test the CPU in another system?
 
Mouse and or keyboard would not need to be connected for system to POST and try to boot to OS.
 
Full system specs would also help us to help you.

What CPU ?
 
Only the debug code that the MB Stops on matters --> (where the BOOT Hangs)
 
It Could be MB issue -- Can you get to the BIOS screen ?
 
Remove ALL connections to case -- use the MB mounted push buttons
 
If you can not remove the MB from case to place on cardboard (water cooled GPUs) -- you must confirm that MB is Not touching anything that could be causing a short
 
What version of BIOS is currently loaded in MB ? (is your CPU listed as supported with that BIOS version ?)
 
Can you test with a older (air cooled) GPU ?
 
Can you test with a different RAM ?  (is your RAM listed as supported with that BIOS version ?) Try all your sticks one at a time - DIMM slot #1 only manual p 1-7
 
Is RAM Voltage and timing set manually in BIOS ?
 
Remember do not over-tighten the CPU heatsink / water block - as excess compression can cause misalignment of the pins under the CPU
 
1) add TIM to CPU and place WB gently on top
2) tighten the 4 retainer screws in a "X" pattern - making sure to turn all screws in sequence and Keeping the WB Flat
3) 1/2 to 1 extra turn on the screws after the WB makes contact is enough --> the springs apply the force to "hold" the WB against the CPU.  The springs should not be in coil bind (compressed until there is no gap between coils)

Thanks we are going to try the OC but have done everything else you suggested.
As for the error codes, I know they are MOBO issues but are they things that can be fixed by setting something
or do they signify a bad motherboard.  Code 19 is early South Bridge Initialization
Code 55 is early Memory Initialization, and Code 60-63 there is no 60 but there is a 63 it changes so fast, that one is Late CPU Initialization.   MSI/They are sending another RMA approval but still wish we could get this one working and
not have to go through the hassle again of sending, waiting installing and testing just to find we have another dud.
I try to be really positive but at this time all I am positive of is that we wish we had never purchased this board.
Any other suggestions?  We are about ready to start draining the water and break it down.
Really appreciate all the good suggestions we have tried them all.

Thanks I appreciate your input As for his system, yes it will be nice if it is ever up and running. He is proud of it. 

The config. is interesting as we have always ran it in E1,E2,E3 we have never used the E4 Slot. and it worked fine.
We run them as Master, Slave, Slave.  The first board worked but had some broken /missing pins so we returned it replacement.
The next one was OK but we could not get all HDD to read, we did tests with their tech support and it was determined that there was a MOBO issue.  Board looked perfect, we sent it back and rec'd a board that looked like it had been through a sand storm, scratched and dinged etc but it worked and then when we tried to update it, it would not update.  Again MOBO Issues with some USB 's..
So we were sent the MOBO that they sent us a disk like we used to get for booting etc but now they come with Flash drives, I have to believe they knew there was something wrong with the flash drive port * special size * because they sent the disk, which worked till we found that it was cracked all the way through about 1 inch into the data.. unable to update bios or even flash drive. Returned and rec'd this board, and it will not boot. The Motherboard and all fans, radiators, pumps etc all work, all memory lights up as do the graphics cards, all very pretty but it will not boot. Flash drive, regular Thumb Drive I copied the new bios on also did not work.
MSI sent me a diagram to rename info on the thumb drive, I kept telling them it was not the same info I needed, then they admitted they sent it for a different board not ours, *our mistake sorry* I wonder who trains their tech support. 
I am getting better information from this forum than I have any where else KUDOS to the forum.
 
Thank you all, each of you who have sent suggestions and or help.  I will keep you informed as to our progress..
We are running a final test and then we will be draining the water...

We have began to drain the radiators/water system.  Something intriguing I noted today. We always use the switch on the case to turn the computer on and off.. but since it was on the other side this morning, I did not want to get up from the floor so I used the switch on the computer itself.  The on/off power switch it did not work, pressed it again for 10 seconds again it did not power off the Mobo.
So I tried the reset button no luck there either. Is this indicative of any kind of specific problem?  It turns off fine at the case switch/button and at the power supply.

Thanks you are all awesome. My husband and I both appreciate all your suggestions.. great info.

What are the specs of this monster? Especially the case? I'm curious!
And also, did you end up waiting for another RMA?

We are waiting for the replacement Mobo to arrive. I told MSI that if this " refurbished Mobo " does not work that we will be demanding a new retail boxed board. We started with a board that cost over 600$ retail boxed Intel Platform and have had to replace it, and then replaced the first refurbished board and now the 2nd replaced board and now we are waiting for a 3rd refurbished board.  I took photos of the board so we will have proof the board was in good condition physically when I sent it back.  I think the specs you were asking about are on one of my posts, the 6th one.  Then we have the X9 3 cubes he has been running for his case by Thermaltake. They were made for water cooling with shelves for HDD and mounting the Radiators and fans sides open with windows *paid for separately* and louvers which come with the case, each side of the top of the case removes separately as well but  he has decided with the smaller SDD HD he will likely go back to 2 cubes but will hang on to the 3rd one in case he changes his mind again.  The cubes each measure 15Wx19Hx25L he paid about 135$ each about 2 years ago, they came in black and white but we got the black.  He said they were made for water cooling and have all kinds of room inside to build a highly cooled system. He also installed heavy duty wheels on the bottom to move them around since the cases are all steel they are very heavy.  Hope this helps.  He is going through withdrawal, so they can't get her fast enough.  Thanks  for asking.

you are correct we can only take their word for it and I am sure as you stated they are not checking out the mobo my maxing out the graphics cards and the memory not to mention I am not even sure they would test it with a " water system " in place, probably only using air cooled memory and graphics and cpu.  So its really not a fair test, but what can we do?  We can challenge them but they have all the techies and they can do most anything as we recently found out.  Thanks again.
