This is a new build everything powers on fine when i first assembled but there was no display or beep. I tried individual ram and still nothing. I then shorted the 2 pins to clear the CMOs (was unplugged when i did so) and when i powered it on again there was still no display and the fans ,instead of continuously spinning ,start up stop and start again over and over, also the clear CMOs button and other LED's keep flashing unlike before. please help.
