uhhh... dude... you've got a big problem before the PSU even....
Look at your first picture, you see that screw thing at the bottom right on the motherboard? That's supposed to be installed ONTO THE CASE, it's not supposed to HOLD YOUR MOTHERBOARD to the case. those are NON CONDUCTIVE "adapter" bolts to keep your motherboard from shorting out on the pc case, you're supposed to use those on the case and tighten motherboard with small philips screws onto those black "tower like" bolts. Right now, more than likely, your WHOLE motherboard is probably shorting out on the PC case.
Maybe see to get some help from a friend or look on youtube for correct installation guides. I think you need to re-run installation guide and see your hardware installed correctly. I don't know which issues you have been having, but at this point, you may even have permanents damage on hardware components EI:motherboard+ other.
only after you fix your motheboard, try the PSU again.
