I just recently bought replaced my friends old motherboard with one I just bought from Asus. I made sure to connect everything properly and the power switch won't boot the computer on. I've checked over and over if I missed the pins I was supposed to connect it to but it still hasn't booted. I've even crossed checked the power switch cords and connected one from another case and it still can't boot up the computer. I cannot tell if the motherboard is defective because my LED mouse is lighting up when it is plugged into the rear USB. Thoughts anyone?
Wait for a second doesn't your motherboard have a error code led panel. It should have many numbers flashing at bootup. Tell me what is being said. By the way if it says AA that means it all ok. Check your motherboard manual for the number's actual meaning.
