I tryed swapping motherboards and once I did pc booted for ten seconds no display and turns off and back on in a continuous loop the board was used with a different proccesor so I decieded to wipe the cmos tryed the button battery and the jumper and nothing so I put all the parts in my original board and this time it stays on but no display all fans spin and the speaker makes a single beep I thought it might have been the gpu so I plugged into the onboard graphics still nothing I checked and made sure all cords are plugged in and they are
