Did I kill my mobo?

So i installed a hyper 212 cooler. Everything worked perfectly before the installation. I also did some extra cable management. Now my computer won't turn on. My psu is able to power on another computer. is there anything else I can try or 100% narrow it down to the mobo?

  1. couple of questions... did you move any of the headers (like for the power switch) while installing? Might you have popped some memory out partially? Did you unplug the 4(or 8) pin power supply for the CPU? Did you unplug the 20(+4) power supply to the board? Is the cpu fan plugged into the board?


    Check these things first as they are very simple fixes, (on all of them unplug and replug to ensure they are in there solidly) There are more ideas floating around but those are all simple and would present as a dead board.

    I completely removed all connections and removed the mobo as it made it easier to install and move cables. The cpu fan is plugged into CPU fan 4 pin connector. All RAM latches are closed so they shouldn't be loose. I did accidentally mix up the jumpers for the front panel but got them sorted out.
  3. Still no love, ummm is your power supply switch turned on? I've had that bite me in the butt before too. (and you don't have to admit it just say its fixed) is it pluged into the surge protector and power supply well?
  4. Yes, I powered on another computer with it then tried my computer and nothing
