I am attempting to build my own computer, and its not working so well at the moment. I ordered my mobo and cpu and I installed them fine, except that theres one hole in the motherboard thats not raised up by the case. Also I can't seem to find the right screws because it's just a case my friend had. I have a few screws that fit in it propery(so I think) but I don't want to risk shorting out the motherboard. Do I need a special type of screw? They all seem to work, and will that non raised part affect anything?
