YOU HAVE SOME CONNECTION LIKE THE LED AND FACE PLATE WIRES IN THE WRONG, CONFIGURATION.
THIS IS WHAT I RECOMMEND YOU TO DO FIRST.
REMOVE EVERYTHING, UNPLUG ALL DEVICES,
MAKE SURE THE MOTHERBOARD STAND OFF THAT ARE IN THE CASE IS NOT SHORTING OUT THE MOTHERBOARD.
make sure all the hole is the motherboard line up with the stand off where you screw down the motherboard.
1.make sure the cpu and fan & memory is installed and plugged in
2.just plug in the power supply, turn on system, if boots, turn off
3. install video card 1 only,turn on, if okay, turn off
4. install dvd unit, turn on, boots ok,than turn off
5. install hhd, turn on ok, than turn off
6. plug in front panel,usb,other fan, turn on, if ok,turn off
7 install network card, turn on, if okay, turn off
if you have any issues with any of the steps above than you will know which unit or item is bad, or plugged in wrong, or not compatible with your unit
I KNOW IT IS ALOT OF WORK BUT IT WILL SAVE YOU ALOT OF RUNNING AROUND WITH YOUR HEAD CUT OFF
