So my motherboard LEDs turn on and my case fans but not my CPU or gpu . the same thing happened yesterday but after a few hours they worked again. Any ideas what the prob is? BTW I can turn on the system with the front power switch but I can't turn the system off the same way, I have to switch the at power off
