Custom pc wont turn on

[ZyroSirus]

Ok so i tried everything you cab think of, re sesting ram, changing power cords and sockets, taking everything out of the case (still nothing) and making sure everything is plugged in and everythings turned on. I have done alot of things you can think of and i just gave up i dont know what to do.. can someone help (btw nothing comes on screen and no fans spin or no lights come on)

Make sure:

• Power is actually plugged in at the back
• Power switch on socket and PSU are on
• Motherboard connector can't just be pulled out, is clipped in place
• Power switch is on the correct pins

If there's still nothing, even if you short the 2 power pins on the motherboard with a paperclip, then maybe your PSU is faulty.

yes，check the power switch in the right pin. The handbook for you mobo should tell you which is wich

One thing that came to mind (because i did this yeasterday)... check if the power button cable that connects from the front of your case, to the motherboard is actually plugged into the right pins

Make sure:

 

- The AC outlet you're using is actually "live". Plug in a lamp or something to make sure it works.

- The switch on the power supply is set to "1" or ON.

- make sure the case's power switch actually works and is connected to the proper pins on the motherboard. You can manually short the PWR pins to check.

-  the case's reset switch is not shorted. Easiest way to check is to disconnect it. (this actually happened to me once and caused several hours of running in circles.:) )

-  you have the CPU's ATX power connected (the 4/8-pin connector on the motherboard)

-  you have the CPU cooler's fan connected to the CPU_FAN connector. Some systems won't start if no fan is detected.

- to reset the BIOS using the hardware jumper, to make sure there's no rogue settings preventing the system from staring.
