I tried clearing bios , reinstalling windows etc everything nothing seemed to work.
So I didn't put any card in the 1st pci-e slot
and put the rest of cards in other slots and let it run for a day or day and a half , that amp extreme 1070 was now in slot 4 or 5
anyways afterwards I had some internet problems during which I couldn't mine so I thought why not try to fix this issue
I completely turned off the rig , attached a 1060 card in the first slot , Others cards still in their slots and tried to turn on the pc.
Too my complete surprise the card worked and every thing is still working 1 month later now.
LOL. Sounds the same as my issue. Seemed to me that Windows do remember some settings and refused to change unless you really push hard...
