right possible soloution take it out the case, put the board PSU and all other parts on a flat cardboard box or sumthing that will stay static free then turn it on if it works, i will be the case causing the problem, because i had that problem when building my new rig turns out that the board was touching the metal base on the case but like i said try putting the insides all connected up on the cardboard box and turn it on then edit: that sounds all shit lol grammatically and stuff forgive me I'm tired NicP
