Is are your fans even turning on? Specifically your PSU fans?
There is absolutely no power goes to the motherboard. No beep or any sound or any fans run at all. I checked all CPU, case, and system fans HDD LED, -P LED, +P LED, Power SW, Reset SW , and Speaker connection are in place including all 12V ATX 8Pins CPU power and main 12V ATX 24 pins.
