Hi forum, i got new Gigabyte HD 7870 and then bought PSU 650W. First, I couldnt run it - i stopped after pushing the ON button - on black screen, so i updated my old BIOS, and i made a little advance. Now i am stuck in BIOS screen, keyboard doesnt work, i cant get into the BIOS settings. With my old HD5850 everything works so there is some problem with 7870. I think its something with compatibility. I have mobo Intel DP55KG. Is there someone who could help me to make it run? I am solving this problem for a week and it really makes me crazy. Thank you
