I was upgrading an old ASUS mobo with a couple of sticks of DDR2 2gb per stick. After I pulled old 1gb and replaced them the board would not POST and case and CPU fans would not spin. Power light on mobo was on.
Thinking it was the possible the PS I replaced it with a tested new one and got same problem. I then stripped mobo down and used old ram in same slots. Same problem. I thought that maybe the board got cracked when inserting the new ram. It took some force. So I replaced the mobo and CPU with new ones. The problem is still there. The mobo is a new one so I used fresh DDR3 RAM as that is what this board takes.
The interesting part is in the problem. The board gets power but there is no beep codes are fans spinning. If the power supply is left on and you slowly insert the 24 pin power connector the fans will spin briefly. Holding the connector in but not putting it all the way in you can keep the fans going but there is still no POST. I checked the connector all over for loose wires, pins, partially inserted pins, and cleaned connector with electro-clean. Problem still there.
Any suggestions?
