i built a computer and got everything working....or so i thought. after checking my device manager i noticed that i literally had no graphics card in there! it doesnt make any sense to me. some one please help i have a AMD Radeon HD 7770. The fan spins on the card so i just assumed it would work until i tryd to start some games and got shit fps. (also i dont know if this matters but i was not getting any hdmi out put also.) plus i could not download any drivers which must be a cause of this. HELPPPP!
