I need help! 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. My CPU is Intel i7 4770 @ 3.4 Ghz. Everything is new, the PSU (750w), GPU(Gigabyte WindForce GTX 760), 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 isn't booting, but everything else is. The cpu fan is spinning, motherboard light is working, PSU fan is spinning, GPU fans are spinning, but the system(windows) 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 start. What should I do? I checked my HDD/SSD and they're working fine. I also connected everything from the case to the mobo. Why isn't my system booting and my mouse/keyboard lighting up(they have LEDs). Also, when I plug in a HDMI cable from my monitor to the computer, I get no signal. I think it's because nothing is booting, or it's just not working! Any solutions?
