I can only start the pc when I remove the 4pin power. Removed everything else and that is where the problem is. Is it the psu or the mobo? Tried with another psu but nothing. Have no way of testing further atm.
When the cable is disconnected, fans work, indicator leds light up, mobo post beeps.
Shall I gamble with the cpu or mobo? As in getting new ones.
E: the pc turned off while gaming with a slight smell.
