So for Christmas I got a new CPU mobo RAM and a new CPU fan and I just finished installing them all and my pc won't turn on. When it's plugged into the power the LEDs on the mobo turn on and work but everything else is dead. The fans won't start and the pc won't power on. I'm sure I did all the wiring correctly idk what to do now. It honestly feels like I just lost 500$. If you could help it would be much appreciated.
