Hello, just got done building a pc with a 970a-G43 motherboard. AMD Phenom x4 965. 8GB RAM 1600. Radeon R9-290 4GB Graphic card. XFX 850 watt PSU. Everything is hooked up correctly. Went to boot and have no picture signal. I thought the MSI board would've automatically detected the MSI Radeon card. Do I need to load MSI motherboard software first or OS first? I tried the OS first. Any answers???
