Have intermittent fault with board boots normal some of the time other times rapid series of short beeps all phase leds light up everythnig spins up then it shuts down and repeats the process. Turn it of for a couple of minutes then turned it back on and it works. Research on the net suggest either psu or mobo, however a majority of info points more to a mobo issue. Am i better of just replacing the psu and mobo with something else.
