Hello,
Currently I have a Dell XPS 8300. With the default mother board. I wanted to upgrade my AMD HD 6870 to an R9 280. I bought a new 600W psu hooked that up and my new GPU. When turning my PC on, the fans spin up normally and such but the display shows nothing, the keyboard and mouse don't turn on either. When I put my 6870 back the computer works fine. I have the latest BIOS version. Any ideas?
Thanks
