Nothing just a green light on the motherboard, pressing the button does nothing, will having I can try having the HDD disconnected, but how could that be the problem? I'm still new to fault finding

Try bridging the green and black wires on the 24 pin motherboard cable.

Like this:

The fans you have plugged in and everything else bar the motherboard will whirr up if the PSU is in good working order.

Have you checked the case cables are really on the right pins. If they are remove the power button connector and either test the button actually switches or with the psu on carefully touch a screwdriver across the power button pins on the motherboard.

Andi.

Quick check list:

You used the stilts the motherboard sits on?

Plugged in the large (20 pin I think?) mobo power connector? (Will clip in)

Plugged in the CPU power connector? (Will clip in)

Turned the PSU power on at the back of the case (assume you must have)?

Plugged the 6 pin connectors into the gfx card? (Will clip in)

Made sure you got the front panel connectors in the right place? (double check this)

If all of that has been tried, maybe try powering on with as little connected as possible, aka remove gfx card and some ram and try.

I've followed the motherboard manual, as far as I am aware it is correct. Ill have to try the PSU test in the morning.

Potty27 · 26 Jul 2013 at 22:09

If I were you I'd pull out the front panel connectors and reinstall them again to be sure, as they are easy enough to get wrong.

Have you tried pressing the reset button? Just in case you got it mixed up with the power.

Are you certain the Cpu and 24pin power cables are connected. The 2 ports circled.

Yep used all the standoffs in the correct places, the large connector is plugged in, the 8 pin CPU connector is plugged in, PSU power is on, both connectors are in the graphics card, made sure of the front panel connections (even youtubed it to be sure) if I'm to only use 1 ramm stick which Dimm should it go in?

Still nothing just the mobo had a green light where the power button is at the bottom of the mobo.

I'd use 2 and stick them in slots 1 and 3, but also remove the graphics card for now.

Nemerus · 26 Jul 2013 at 22:17

With the CPU cooler I'm unable to access slot 1, it mentions in the manual for dual to use slots 2&4

Make sure the clear CMOS button near the PS2/USB ports is not being pushed inwards by the I/O shield.

If it's not that try shorting the 2 pins where the power switch connector goes to rule out a faulty case button.

Potty27 · 26 Jul 2013 at 22:23

Sorry, yeah 2 and 4 should be fine.

Potty27 · 26 Jul 2013 at 22:24

Once you've tried without the gfx card, I'm all out of ideas.

Only thing I can think of is possible faulty power button or PSU maybe.

No CPU fan spinning?

Seriously, this should be one of the first things you try.

wazza300 · 26 Jul 2013 at 22:35

Either the board or psu imo

Idleman · 26 Jul 2013 at 23:20

What happens if you use the mobo power button, found bottom left corner?

opstrat · 26 Jul 2013 at 23:40

what case do you have?

this is where i went wrong building my new PC... i didn't plug both in as i thought it was either one or the other and if i used both i might fry the mobo. I then realised i had both cables and my friend told me they both need to be in!!!
