4 * GTX 1070 , MSI Z170A M5 and Windows 7 Mining Rig Challenges

Hi Guys ,
First thank you so much for the suggestions.I really appreciate it.
Here’s what I did
Updated the BIOS to the most recent version here V384.76
Spread out the power connections to the cards and the risers with separate cables each riser drawing power directly from the PSU with it’s own cable
Use DDU to unistall current driver version
Connected all the cards using Risers
The results were :neutral_face:
I saw all the cards under device manager but one card showed missing card drivers

So at least I can conclude that the risers are not messed up.;;though I order some new ones…:neutral_face:
When I tried updating the drivers a blank screen came and the windows restarted to a restore point that didn’t have drivers (this was created during DDU uninstall)…:disappointed:
Disappointed I went to plan B to remove the card and try mining with 3 cards…
So with 3 GPUs here are the result :expressionless:
First connection

Results:-
The computer froze for 30 min until you restart from the power socket to restart
With EWBF Miner the computer froze gave an error then a blue screen

After the above I get a blue screen.

So I decided since I have 3 *16 PCIE ports on the board I just connect all the cards directly on the board try mining from there…so my connection is as below…

I was able to successfully mine for 3-4 hours on with good numbers

Until this happened :anguished:

The above happens with EWBF’s miner and then the miner exits.
With nice hash the following happens : -

Excuse my image…!!
I managed to fix the errors by restarting my machine and lowering the overclock on the cards.
Currently still mining on the board…:cry:

Thank you again for your suggestions and and more so for reading this…:+1:
