I've recently bought the Radeon R9 280x gpu and proceeded to mount it on my mobo.
Sadly I don't get any video signal, and the Doctor Debug signals me with an error 97. The gpu is correctly powered (using one 6 pin cable and a 6+2 one) from a Corsair TX750 power unit (which should be more than sufficient).
I had to revert to my old video card, and the system works finely (I had removed the drivers previously, of course).
I'm lacking ideas, I still have to test the video card on another pc but I really need advice.
Thanks in advance
