Did you check if your board is sitting on the motherboard tray properly and not crating a short? Also check if there is any issue with cpu pins on the board? Take a closer look at the board, and see if you notice any change of colour? Did you try booting the system fully assembled out side the tower? Like a test run...
I'll check the board tomorrow for discoloration. I did check the CPU pins, they seemed fine. It seemed to fit on the tray just fine. I did a test boot before I installed everything in the case and it was working fine.
I'll do another out of vase build tomorrow to see if it will work, although I'm gonna need more thermal paste now haha. Thanks for the help so far everyone.
