Random crashes, restarts and black screens

[Akaash]

Hiiii everyone,
This is my first multiple GPU rig... Specs are as follows:
CPU G4400 dual core
5 GPUs Inno3D GTX 1060 6GB
MoBo ASRock H110 probtc+
SSD Kingston 120 GB
PSU Corsair RM1000x
RAM 4 GB Kingston
Risers from China
OS Windows 10 professional

All GPUs are on risers attached on to 1x PCI-e slots.
On sysinfo under display it recognises all 5 GPUs but only 4 have IRQ channels while the other one doesn't. It is running on driver version 21.21.13.7563 . The 5th GPU also doesn't have memory address.

My problem is that I have random crashes and blue/black screens and innumerable restarts...

I haven't started mining yet...

Can somebody help me...
Where have I gone wrong?

You've got a few options:

1.)  I'd check the Windows System Logs to see if there are any events that could narrow the issue down.
2.)  How many watts are you drawing?  Do you have a Kil A Watt http://www.p3international.com/products/p4400.html to see if you are close to the max of your power supply?
4.)  With Nvidia 1060 cards I'd try Equihash coins which will use the EWBF client https://bitcointalk.org/index.php?topic=1707546.0
5.)  I'd install MSI Afterburner and the top line of each card I'd lower the power to 75%.  If your power supply is close then lowering the power to all the cards will stabilize things.  

Really though it would have to be power or a device driver/hardware causing the issue.  I run 5 1070s but I use two 750 power supplies just to make sure.

Checked my driver for my 1070s:  22.21.13.8528

Also I recommend watching this build from Bits Be Trippin: https://www.youtube.com/watch?v=KywQWbDA2FM
  -- he builds a 13 GPU using your motherboard and generally he covers a lot of stability issues like BIOS, etc.

Have you tried to remove completely that GPU, it can be that one GPU can cause the blue screen of death.

Try each GPU to remove and see which one cause the problem, if none of them try removing one RAM (if you have two) and/or change with another one.

Thanks guys...
I wanted to know if my risers or my PCIe slots had any problems...
Right now all my risers are running fine.
The PCIe slots however have a different story...
Except for slots 2,4,8,13 none of them are able to display my memory address... However all of them recognise it to be a Nvidia 1060.
I tested on all slots with the same 16x riser and 1x riser.

Any help on this issue?

And yes will update my driver to see if things work out...
