Hi, I just bought a G5. Its 2.0 DP that is supposedly working according to seller. When I got home I tried turning on the pc. When I press the button there is the chime and after a few seconds fans start running at full speed and there is folder icon on screen. I tried with different hard drive that is known to work and the same thing happens again. I dont have the original keyboard. I tried reseting nvram but nothing happened so I dont know if I was succesful at reseting it... So does anypne know what could have happened to G5?
