I got an ASUS motherboard for my new pc build and I had 8 screws for the 9 grommets and I used one different one. I pulled the 24 pin power connector out and the different screw came out. I heard a little creaking, but I checked the motherboard thouroughly and it looked brand new. Could it be cracked or am I being ocd. It boots up and runs fine but I like having a perfect unit. I can't seem to see anything wrong it looks fine.
