Lots of Blue Screens on new build - thinking dodgy Mobo

Can I get help to analyse these BSODs please. I have a horrible feeling my mobo is knackered but will try anything to avoid RMA'ing it.

Don't have a list of all the BSODS but will list them as they appear.

Currently have 2 written down, but I have also had Page error in nonpaged area, driver irql not less or equal amongst ones I can remember.

Here's 1;
