Having a hard time mounting my motherboard

[Jeffdom55]

Having a hard time mounting my MSI Z77A-G41 motherboard in my .NZXT Source 210. I looked in the booklets and can't figure it out. Am I using the wrong screws or something?

Case: Gotta mount your own screws. ATX
Mobo:ATX

Are you using any risers? You have to screw the risers into the holes in the case while making sure they lined up correctly with the holes on your mobo. Then once your risers are in place, place the mobo on top of them and attach screws to them.
