Yesterday I received all my computer parts and I put them all together. Everything is connected correctly (at least that's what I think). The problem is, when I turn on the computer, I'm not getting any display and the bios won't load. Completely NOTHING appears on the monitor, it's just a black screen. Also my hdd and cd drive don't have lights on. Please help. Thanks
