Are you certain you plugged in the JPWR2 connector and the JPWR1 connector?

what gdmaclew said. There are two power source going the m/b (JPWR2, 8 pins located next to USB back ports and the JPWR1, 24 pins connector). And Graphic card power.
Does it boot into BIOS?

Do you have 1 RAM DIMM or 2?

1 ram of 4gb

I'm not surprised that the single stick of RAM doesn't work in slot number 2.
Most motherboard manuals explicitly state which slot to use with a single stick of RAM.
Your manual doesn't. It only shows 2 or 4 sticks.
But you can be sure that if 2 sticks use slots 1 and 3, that 1 stick should use slot 1.

Ummm...can you explain in other words? Are you saying that my ram slots are perfectly fine?

I don't know how else to explain it.
Your RAM slots should be fine.
