Hi all,
I recently put together a PC but when I tried to turn it on nothing happens. There are lights on the board that comes on (SATA lights) however the PSU fan, CPU fan, and chasis fans don't turn on. Is it possible my mobo is defective? Or is it possibly my PSU , GPU or CPU? For my CPU I think I may have tightened the cooler down too much (Hyper EVO 212) if that may affect anything.

Motherboard is an ASUS m5a99x evo r2.0
CPU is FX 6300 which I know works since I'm carrying it over from an older build.
GPU is a Gigabyte Windforce 660 OC
PSU is a Corsair CX500M.

Any helps is really appreciated!
