Only GPU lights up when I flick the psu switch on

[Conleak]

Hi, so I recently built a new computer and I'm pretty sure I got everything right. When I try and give it a test run, before putting the sides on the case and connecting the PC to the monitor, nothing happens except for the GPU led light coming on. I've looked everywhere for a solution and I'm yet to find one.

send us a picture.

have you got both of the mobo power supplies plugged in, the gpu power, this could be the case if the reset switch is connected to power switch pins on mobo perhaps?

What is your configuration. Do coolers run?

Everything is plugged in and I'm pretty sure I've got the pins right. I checked the motherboard manual and the only thing I think it could be is that the motherboard shows all the pin headers as being 1 pins. But in my case some of the pin are two headers so they take over an extra slot.

The coolers do not run. The only thing that shows signs of life is the video card's green lights coming on.

What is you motherboard? is mobo led on? check atx24 and cpu power connections.

Motherboard is asrock h77m. The motherboard light isn't on and I've checked the connections, they all seem fine

check if power sw cable plus and minus pins are connected with appropriate pins on mobo. try powering on by touching power sw pins by screwdriver or try plugging different case power switch connector.

I don't have a power SW minus pin. I pretty sure all the pins are in the right place. I don't think anything happens when I touch the pins with a screwdriver.

you have a pin problem, if they are all x2 on the mobo and some of yours are x3 then you need to makes yours x2. There is no +/- on the power sw or the reset sw they are just switches, the leds do have a +/-.

 

[Conleak]

No, some of them are x2 but the mother board is x1.

 

[13thmonkey]

no the mobo will have two pins for each switch, it has to have, switches don't work on just one pin.

I've put the headers in correctly. The PC doesn't start or the fans don't turn when I touch the power switch pin with a screwdriver but the screwdriver is rusty, would this affect it?

I'm going to be a good guy and actually write my solution on here. So I basically removed everything.

I disconnected and took out everything except the CPU and the 2 power pins from the psu. I tested the PC by tapping the power button with a screwdriver. I did this through every step of installing hardware and that's that!
