Reset the Cmos?

Maybe a silly question, but are you powering both portions of the motherboard? There are two rectangular power points on the MB. Next to the cpu socket and to the side somewhere.

I made this mistake on my first build

got all the power connectors plugged in?

Have you tried the power buttons on the mobo as opposed to the front panel ones.

Have you tried with just one stick of ram ? may need voltage adjustment for all to work.

Try building outside the case first, to rule out the case shorting it when you're turning it on.

If the PSU's have modular connectors make sure that they are firmly plugged in.

Sounds obvious I know, but it stopped my new build powering up, until I lightly touched one of the cables, and it virtually fell out of the PSU!

Gave it a firm push back in, heard a slight 'click' and all was well.

ok going to try this

smithy83 · 15 Dec 2011 at 11:48

ok i have the motherboard out of the case on a anti static bag
i have the board with a minimal things plugged into it (no sata cables,1 stick of ram and no gfx card the monitor is plugged in via the on board dvi power cables are all in)

same result no sign of life at all i also cant see any damage to the board

lrlcr · 15 Dec 2011 at 11:50

right, tried all the sticks of ram? (just because it's hugely unlikely that they've all gone!)

RMA

smithy83 · 15 Dec 2011 at 12:04

yeah just tried different ram sticks in different slots still nothing

hmm seems like a dead motherboard then i guess.

if there is nothing else i can do its rma time

thank you all for your help

Try losening the cpu cooler a little, you might have gone overboard.

Deception · 15 Dec 2011 at 12:10

Are the fans spinning up at all when you try turning it on?

Dont use an antistatic bag, the outside is conductive.

use a cardboard box or wooden tabletop.

the only fan what was spinning was the fan connected by a molex to the psu the fans connected to the board cpu fan and another case fan was not spinning

i have the cooler off and just checked the cpu and socket they look fine

dead mobo (possibly cpu but unlikely)

Does indeed sound like a dead mobo, as im pretty sure you have made sure all PSU cables are in (24pin and 4pin power).
