Every square/roundedsquare plug on your motherboard needs a connector in it.
Don't get me wrong Ron, I'm glad to see a new member contributing, but when giving instruction to people with less experience such vague statements should be avoided. They could be misunderstood
Treasure, Just deal with the plugs shown in the link I gave. the large 20+4 goes in the only spot that will fit them all in a row. Half of the 4+4 goes in the 4 pin by the CPU. If something else is broken, this needs to be fixed either way for us to diagnose it.
