James Manns · 18 Jul 2010 at 21:32

ive just tried it with one and it did nothing, its asif its doing shuting down like a fail safe ??

You can double check the PSU by linking out pins 16 & 17 on the main ATX connector, but I would remove all power connections and connect a fan to one of the molex connectors.

Unfortunately I know we have said it several times is try external to the case to rule out any shorting, I have had to do this with fault in the past.

is that the green and black one to run it with it being connected, i did that earlier and it was fine .

RJC · 18 Jul 2010 at 21:58

That's the one

James Manns · 18 Jul 2010 at 22:00

yeah, it worked fine with a few things on it. its just as soon as i plug the board in and try to tunr it on, it just goes on for about half a second.

Hi all!

James Manns; my set up turns on for a split second and then turns off by it self, this only happens after I have unplugged the power cable from the PSU and then re connected it. 5 seconds after it has turned it self off, it then powers up.

Hope this info helps!

i dont think photos would show whats wrong?? i just need to know what ppl have done that i may have done wrong.

ive got this problem as well. im thinking its the psu or either motherboard is nackered. as its only done it couple of days ago so im clueless on how to get mine working as well. so if any one finds out please let me know as well. yeah mine does same owers on for half second. the fans and everythink power on for half second to. then just turns off. it also makes this funny slight buzzing sound when powering on.

James Manns · 18 Jul 2010 at 22:35

EXACTLY THE SAME ! makes like a high pitched noise/ buzzing noise

Orcvader · 18 Jul 2010 at 22:47

My first build had the same problem. Take everything out and place it back in.

James Manns · 18 Jul 2010 at 22:59

is there a way of sorting it without having to do that as ive got my wc set up aswell?

whipitrnd · 18 Jul 2010 at 23:07

yeah same as mine. hmm i dunoo im thinking my motherboard is messed up. due for a new cpu and motherboard anyway.

If you've got a clear CMOS switch on the back panel of your mobo then make sure its not being pressed in by the I/O sheild, took me a while to figure that out!

If you're really stuck i dont think im that far away to cast another eye over your pc.

James Manns · 18 Jul 2010 at 23:11

i dont think there is a switch to be pushed in :s
you could do, but i never know when im in.

Danm54 · 18 Jul 2010 at 23:17

Maybe try unplugging everything you dont need, run 1 stick of RAM, one HDD or SSD, graphics card and maybe 1 or 2 fans. Also check that the pins in the power connectors are fully home, they've not popped out when you've plugged it in.

James Manns · 18 Jul 2010 at 23:20

ok, ill have a look

James Manns · 18 Jul 2010 at 23:24

that hasnt changed anything either, when it gets power for half a second a couple of lights come on, on the board.. ?

James Manns · 19 Jul 2010 at 11:08

is there a reason why this usually happens ?

Kanpai · 19 Jul 2010 at 11:15

Had the same problem with my new build, turns out the Case power connector wasn't connected properly onto the mobo so was cutting off. Do you have a power button on the mobo itself?
