Ok so basicly the drive wont detect when i add another gpu to my gf's pc so she can mine some more coins. Light behind it glows red, in bios theres no boot device.

Mb: asus z170-a
Gpu1 asus 1060gtx 6gb oc
Gpu2 : the new gpu, also asus 1060 gtx 6gb oc
Hdd: vnand ssd 950 pro m2 samsung

Works fine when i take the 2nd gpu out.
2nd gpu works fine on my other pc.

Figure theres some bios settings but i am a newb so have to ask :)


Oh and powersupply is a evga 750g2 supernova 80 plus gold

Not sure how exactly id figure that out but that was the general idea in my head when the problem occured,
Would in that case mean that the only slot i can actually put a 2nd card in the cabinet would be useless..

Unless there are options to rerout the circuit in the bios through another port?

Any suggestion on how to check if this is the problem? :)
