How to restore chipset RAID 5?

Question

RAID

A year ago, I assembled a car for a videographer I knew, and I got the following config:
Core i7 5930K
32GB DDR4 2400 HyperX Savage
MSI X99 MPOWER
EVGA GTX980
4x 3TB WD RED
Samsung 850 EVO 256
Chieftec Nitro 2
What happened:
Almost a year has passed. This afternoon he calls me, says - does not start.
I come, I see this: the board does not squeak, the post costs 00 or 04. I started to masturbate it, turned everything off, without a video recorder it squeaks on the video recorder. Returned the video recorder, the system starts. Off on - again do not start. Let's shoot the memory - it starts with each bar separately. Returned everything back - it starts. Damn
it, I reset UEFI, but I forgot that RAID 5 WAS BUILT there
I put the controller in RAID - I see all the disks, NORMAL Raid mode, I think ok, I boot - I get a BSOD Non Bootable device.
The system is clear hell on the SSD.
Let's shaman twist the UEFI settings - no way. Windows won't load.
Without RAID, I get into the OS, I see its sections, Windows wants to format everything.
After the next reboot
, I see the RAID Initialize status I go into the controller, but there are no functions there! WHY THE STATUS HAS CHANGED - I DO NOT KNOW.
The board hangs on post code 79 every time the UEFI settings are changed after the reset
. I can’t get stable work from it.
That is, I can’t start up normally, and the RAID is covered, and there are 2 works that were not handed in, it doesn’t have copies, everything, as usual, depends on me. If we lose data, one family will be left without a wedding, the other without baptism. I can only buy a disk to restore 6 TB of information on credit.
Guys what to do?
How and how can I extract all the data from the RAID?
How and with what can I make the board work normally?
UEFI has not yet sewn from her, she behaves inappropriately.
Can I rebuild RAID on my GIGABYTE GA-X99-UD5 board? One hell of an X99, my car is absolutely stable.
For now, we’re laying down for non-start, I don’t know what to do with the raid. As all the data will be on my disk, then we will think about what to do next.
Thank you all in advance.

I would recommend that you contact the experts. Data recovery from RAID is usually not cheap, but with NTFS everything is usually easy (for a specialist). At the same time, they will check that all disks are alive.
If you want to force launch the old raid - there are many ways to break everything: launch a rebuild with an incorrect configuration, launch the correct configuration with an irrelevant participant (the last year it could work with 3 disks and if you persistently return the 4th to its place, it will become much worse), write down what something on top, etc.
If you want to experiment - do it with copies to avoid writing to discs. Try to remember or find out the parameters with which the original raid was created and, for example, build the same software raid in read-only mode (for example, using mdadm).
