I would really appreciate some help on this one. I recently bought an Asrock 960gm u3s3 motherboard and paired it with a Phenom II X6 1100T, hooked up all the cables from the PSU, installed all of the case stand-offs, and connected the front panel headers in the correct places, but when I press the power button, nothing happens. Nothing at all. The PSU I have was working just 30 minutes before this. Can anyone point anything I may have forgotten, or possibly done wrong?
