I recently purchased an AMD Firepro W7100 as a budget gpu for a cheap build, I'm limited on budget. The motherboard started to go out on that build, so I rebuilt a Dell XPS 8300. It came with a Radeon card, but it was faulty. After installing Windows on my SSD and getting it up and running, I tried to install the gpu. When it's installed, I get a black screen both from the motherboard and gpu. Everything is properly seated and connected. Please help with ideas and suggestions. I'm 2 days into this build and at a loss.
