i have a motherboard and i want to test it without a cpu because because im buying it later, I search that when you power a motherboard without cpu It will Power on but not post or boot Just Running fans and lighting up the power button,but when i press the power button there is no fans running,beeping,lighting. i remove all the Parts and test it outside to the case and Jump start the front panel Pins to the motherboard but the motherboard is still not running, I tried to jump start the pins of the power supply but the Power supply seems working fine,When im checking the motherboard if there is a Blown Capacitors,etc but when i check it There is No problems in to it, When i notice at the back of the motherboard There is a 2 spots but i think thats a normal thing. Does my motherboard is defective or its just a normal thing to happend?
My Motherboard is GIGABYTE B450 I AORUS PRO WIFI(Mini ITX Motherboard)
