We are building my computer right now. We got everything in. We plugged the computer in and powered it on. 3 fans started spinning: the 2 on my graphics card, and the one on my processor. But the computer isn't displaying anything. We plugged it into a monitor and nothing happened. We haven't plugged anything like mouse or keyboard in, and the monitor is telling us that nothing is plugged in. There were also 6 others fans in the case (they came preinstalled), and none of them are spinning.
