Hello, I have got big problem.
I have got MoBo Gigabyte MA74GM-S2H and Sapphire 280X Dual-X.
Display is black when I try to use dedicated GPU. When I disable integrated GPU, then it beeps after reboot and nothing else happens. Also my LAN Adapter isnt working correctly. It works for about five minutes and then it says, that no cable is plugged in.
Can you help me with this please?
