So I got a case and moved everything from my old case into the new one. This case is the Phantom 820, and the when I press the case power button (which is connected to my mobo) it powers up. My motherboard is ASUS Z87-PRO LGA 1150 Intel Z87. Everything is new, the PSU, GPU, and everything. Why isn't my system booting? My CPU is in the mobo and seems to be working. What do I do? The system is booting, but everything else is. The cpu fan is spinning, motherboard light is working, PSU fan is spinning, GPU fans are spinning, but system is not booting. When I press the power button on the case, all that happens is my computer's led boots and all my components open.
