Another thing I would look for is shock to the case, could have been dropped, damaging some of the components like the hard drive. Also, common problem I see with new builders is that they don't always use the correct amount of stand-offs, put them in the wrong location, wont use enough screws, all of these could lead to improper grounding of the system. Also looks like this mobo is a farely bad one, people are giving it bad reviews for being defective and dying.
