I just built my PC, but the only way I get it to start is by forcing down the 24 pin connector into the motherboard. When I release the pressure, it just turns off. Why is this and how do I fix it?
One of the wires may be loose from the connector. At the end of the wire is a metal cylinder connector with a barb on the outside of it. The metal cylinder is inserted into the proper position in the connector, and the barb on the cylinder keeps it from backing out of the connector. Sometimes a wire will get pulled or maybe wasn't fully inserted in the first place and it will come out of the connector. It's probably one of these wires is not pressed all the way in. This happens a lot with the 4 pin molex connectors. Gently pull on each of the wires going into the connector and see if one of them easily pulls out of the socket. If so, push it back in until it's fully inserted and won't back out.
Could be a number of different things but most likely its a loose wire on your pin connector or you may have a bad pin on the motherboard. When you put pressure on it, it makes the connection and starts the computer. However the connection is lost (and the PC powers down) when you remove the pressure.
