Hey, I have had problems with my rig for weeks now. I have asrock btc r2.0 mobo with 3x 1060 3gb and 3x p106-100 mining edition gpu.

First problem is that windows recognizes all gpu's, but when I run nicehash with, for example, EWBF miner it says "thread exited with code 30", then I restart nicehash and EWBF works fine with 5 gpu.
After few seconds one of the gpu's Sol/s starts to drop and stops at 0, others work fine all the time(except the 6th gpu, which I am still figuring why wont work even though it is recognized in device manager.

I have tried getting new raisers, reinstalling drivers with DDU...

Any help would be appreciated!

try a different miner and point it to nicehash equihash stratum port
that should work but auto switching for profitable algo will not work

Have you tried unplugging all the cards but 1 and see if it a problem related to one card? Does the system crash or is it still usable? When it crashes are all the cards still listed in the device manager?
