Hello!!
I am very frustrated and a bit lost...I hope to find a solution because I must upgrade 2 machines and...
Well, I am a composer from Barcelona, and since a year, I realized than I needed to get a second computer to assist to my main computer, an I7 4770k Haswell processor. I Always wanted to have a Mac Pro, but for many reasons, never I founded the moment...until fews months ago.
But then, I realized than I could upgrade the processors following a lot of posts from here, from there etc, upgrade the OS X from Leopard, Lion to El Capitan etc, more ram even now, actually, I give you the Mac pro 2006 with El Capitan 10.11.5 and in a additional partition, Windows 10 with DirectX11 as an option in a dual boot!! And it goes perfect!! I am really satisfied because I can get all the 32 GB of ram with both operating systems, when until now, I thought this could not be possibly more than have a windows 7 32 bits...
Well, having said that, I buyed 3 mac's 2006 to make them the complete upgrade with several Geforce gt8800, 32 GB of ram, X5365 3.0GHZ 8 core cpu's (as always I did with the previous 11 Mac pro sold, everyone without any single problem! and now...now comes the problem I find actually, very strange to me...I repeat, I did this 11 times before with full succes!!
After to replace the processors (sometimes the old ones are 5160, or models with 2 cores at 3.0ghz, or the 2.66 common models) for the X5365, and ALWAYS from a partition of Snow Leopard or Lion, and checking than the processors are functional and operative, I see the common message on "about this Mac" of "processors 2 x unknowed 3.0 ghz"...Yes, I know...I need to do an upgrade of the firmware with Apple tool firmware update 2006-2007, a tool that you can download here in this web! so...I did always the same process..I connect the machine to internet, and I open the aplication, bla bla..I turn off the Mac, I start the Mac holding until I can hear the large "beep", and the process to update starts, and finally, the Mac starts normally, this time, the new processors are showed as "2 x dual xenon 4 cores 3.0ghz".Ok!! It's correct...
Well...so the big problem starts when I RESTART (reboot)maybe at the seventh or tenth reboot, I write this so because I don't want to read 100 times than I go to look in other posts about the "Msc doesn't boot" !! No!!! The Mac boots perfectly, all software and hardware if perfectly operative!! for many hours! and even if you are in reposed mode!!...
Resuming, the Mac's (now I have two with the same problem and I don't want to take the risk of do the same with the third one) BOOTS perfectly!! works great, fast, quiet...but, if I need to restart, for example, after an upgrade or so, the Mac don't make the "chan!!" typical sound, you can hear a sound like if it wants to read something in the dvd drive, and the leds on main board diagnostic CPUA and CPUB FAIL are in red, just blinking a second, and a endless loop with this starts...
I tested all I can find through Google, the best Apple forums, Apple manuals trying to understand what these lights means...Nothing!!
I tested SMC reset, VPRAM reset, Main board reset, I changed the cr 32 3 volts battery, I tested with different hard disks, with OS X from leopard to El Capitan (this last one with its Piker Alpha Efiboot) etc etc...
The most frustrating thing, it's this job I did 11 times before and I never have a problem like this!! At first time I thought, one of these 3 Macs, have some kind of problems..maybe related to main supply, or..logicboard..but it's very difficult cos the first I do when they arrives is checking!! and always has been perfect...so, it's too much chance, 2 mac's are "broken" , no matter what I do after...
The third one, now has the new processors inside (x5365), gt8800 GPU and 32 gb of ram...but, works as ever because I do not firmware upgrade as always...but, I need to do it!!! and I am afraid to do it cos 3 macs with the same problem...I will need to close my shop!!!!
Please...I need your help!! and I write all this cos I need anwers based in things than maybe I forget to do, I am sure it must be some kind of ********!! but...you know? when you ask something to Mr Google and there is NO response about this, particulary, it's very frustrating!!
So, I hope you can give me some kind of "light" with this
Tahnks for reading this and thanks in advance to all possible answers!!

Well...Once! The setup of volume was zero and could not hear the classic sound of start...but no, normally when I feel something so, I check the output of volume...
