Ok so I have a MSI gtx 950 OC, used and proved working. I also have a MSI B350 PC MATE with a ryzen 1600x slotted in.
Now the weird part. Whenever the gpu is in the top reinforced pcie slot (I want to use it to help gpu sag etc.) the pc turns on with power and the motherboard starts running through DRAM Cpu etc. (This motherboard has "Ez Debug LEDs), as I've said before it runs through ram and cpu fine but gets stuck on gpu.
Now if I was to plug it into the bottom pcie slot it loads everything fine and proves that gpu is fine.
Any help is greatly appreciated,
Cathal
