[SOLVED] Motherboard powers on and the usb devices work but pc won't turn on.

[Fdamads3]

My PC won't turn on after I tried installing a new hard drive. So now whenever I try pressing the power button on my PC only the USB devices are powered but my PC won't boot up or show any post. I tried replugging in my power switches and reset pins but that still didn't work at all.

My specs:
I5-2500 CPU
Asus P8Z77-m pro motherboard
Rx 560 graphics card
600w evga power supply.

There is a decent chance that it may be the GPU. Try plugging in the display to the cpu and see if that works. You probably just nocked something lose, try checking all the power power cables from both the PSU and component ends. I would also try disconnecting the new storage device and see if that makes a change.
