gana pa man ang memory when i try on other pc. when i pick out my vc and memory it beeps. i was confused if my mobo are damaged why is it the cpu fan still spinning and the led lights up on mobo. i tried to remove all peripherals and extras, ayaw pa ring gumana, my monitor light up in color green blinking, it says "Monitor are in power safe mode". again no power on keyboard and mouse. is it possible that my psu are defective?
