Always disable the igp on cpu.Edit: Also you may think a riser works when it really only works in one position. This is specifically for ribbon risers. They tend to lose connectivity in certain positions. I found this to be the case for all ribbon risers regardless of how "flexible" they are advertised to be. To rule out the cpu, make sure there are no ribbons or anything connected to the pci-e slots and test the igp on cpu.
