I have an old Biostar A880GZ motherboard with a Phenom II 970 black edition cpu. I tried putting a brand new GT 730 in it and the pc wouldn't boot. I take the gpu out and it boots fine. I went to FB and asked on some pages there and it was recommended to update the bios but for the life of me I can't figure out how to do that or if that is even my issue. I went to Biostar's website and dl the newest bios for my motherboard and also a bios update utility but it doesn't look like it updated anything. What would I need to do to get a newer gpu working in this old rig?
