Claymore - GPU#0 only don't work

[condom-juice]

Hey there what's up 

My new RIG (R9 390 8Go) have a problem : The GPU#0 is recognized, but stay to 0M/h. (sometime 100m/h, i see his normal hash very rarely (800Mh/s).

GPU#0 is on a PCI port
GPU#1 is on CPI-e port, work fine
When I replace both GPU, same thing : PCI port bug (so it's not the card)
Same problem on Claymore for ETH and Claymore for Monero

Windows 8.1 x64
alimentation 700w
8Go ram

Someone have an idea ? =)

Often when people have that issue it's because they have their monitor plugged into one of the other pci-e slots and not the first full slot on the mobo. You should plug into the first full 3.0x16 slot on there which is usually the first big slot from the top.
