Why is my computer not turning on?

[Nathan Gorgona]

My computer won't turn on for some reason. I have a CoolMaster HAF 922 as a case. I opened it up and tried to fix the audio and microphone jacks but can't solve it so then I closed the sides with the thumbscrews. After that I plugged all the wires in mouse/monitor/hdmi/etc. I press the power button then it does nothing 🙁 All I see is the light for the processor lighting



Did I unplug something? I saw these wires that are not used in the case with cable ties on it so I decided to take off the cable ties to look for the audio thing to put onto the motherboard but couldn't find. So I just sort of smushed it back. Maybe doing that made it not turn on?

Check carefully that all power and data cables that are supposed to be connected are actually connected properly.
