I'm having trouble getting my computer to recognize my ATI Radeon HD 7970 Sapphire GPU. I'm guessing it's a hardware problem, but I really have no idea. This GPU works in another computer, so I know the GPU is fine. I connected the card to my computer and then did a completely fresh install of Linux Mint 17 XFCE. But Linux doesn't "see" the GPU. The GPU fans are running, so I'm pretty sure the hardware connections are right.
When I power on the computer, the screen is blank for 10 seconds or so and then the BIOS screen shows up. I know that can't be good haha. Also, when I connect my monitor to the GPU card, nothing shows on the screen, not even when I connect to the monitor BEFORE powering on. I couldn't find anything in the BIOS settings that seemed relevant to my problem (like if there was an option checked to disable new hardware detection).
I double checked that the motherboard supported the GPU. My motherboard is a Gigabyte M61PME-S2P. The GPU's compatible with this motherboard according to this site:
I tried installing an AMD driver that I know works for this GPU, but I couldn't complete the installation because Linux wasn't detecting the GPU.
I'm out of ideas. Anyone else have any?
