This comment bothers me:
Also when I first turned on my computer, all the lights in my house went dim for a second.
Looks like a power related issue.
NOTE: Your room lights should NOT dim when turning on your PC unless the circuit is heavily loaded or there is some other electrical issue.
All CPUs are extensively tested prior to boxing so unless there is physical damage to the CPU when removed from the box, chances are the CPU is fine and there is something else wrong.
I don't see any video card listed in the above hardware. The Athlon X4 860K is a CPU and does not have internal graphics so you will need to install a graphics card.
If you have a graphics card installed, then I'd install just one DIMM in the preferred slot per your mobo assembly manual. I'd carefully remove the CPU and check for bent pins. If all is OK then re-install making sure to align the CPU in the socket with the alignment mark on the corner of the socket. Carefully remove all power and video connection cables and re-install carefully to be sure they are fully seated, then boot again.
"and a MSI graphics card."
Sounds Like he has a Graphics card to me.
