Hi! I just built my first computer and although it powers on it isn't displaying on the monitor. It may or may not be giving USB power, also.

When I power on the machine, the case fans receive power through the motherboard. The ram works in another machine, and the video card works in that other machine as well. I'm also using the same monitor and video cables with the known working computer. I've tried moving the ram and the video card. I've checked the CPU for damage. I don't know what else to try.
