Windows 7: New Build: Restarts instead of Shuts down

I've checked all the wires a thousand times (i had put them in wrong when I first made it so carefully redid it then )

Could it be anything in the case wiring itself?

Pretty convinced it's the PSU now though. Someone I asked said something about power going to the reset switch when it shouldn't be, but I wouldn't know where to start fixing that...

well to determine if its the case or not, unplug all of the case cables, and then manually touch the 2 power pins together with something metal. dont worry you wont get a shock.

then shut down the pc as planned. if it shuts down fine, then its a case issue, if it doesnt then its not the case so you can plug the all back in.

Well, it's not a case issue!

I'll try to nick a psu off somewhere tomorrow and try that. This problem's getting on my nerves now. It's annoying because it's so trivial!

I don't think it's your power supply. If it was, it would shut off and on randomly (not on demand).

This sounds like the power shut-off micro-switch (on the mobo) is a configured 'the opposite way' than what the designer of the computer case had in mind. Typically, a 'normally closed' switch as opposed to a 'normally open' switch.

I would refer to the manual that came with mobo - and find out what the 'normal position' of the mobo's power switch is. If this information isn't on the manual, try this: disconnect the power leads from the mother board (usually, two thin color-coded twisted leads with a plastic connector at the end). Turn on computer, and turn off from Start menu. Computer is NOT supposed to turn off (because of disconnected switch leads) - but it should not restart either. If this is happening, than we know where the problem lies (= incompatible switch configuration).

Could you give this a try?

Paul

if you were to touch the 2 reset pins together when the computer is off it will do nothing. Like i said reset or power, both are just simple switches, the only difference is what we use them for.

And that wouldnt account for the fans still spinning.
My point exactly. Both switches are identical except for size and placement. OP said it restarted immediately after holding the power button in, that's exactly how Reset works, so if it's connected improperly it would do that. During reset the fans, lights, etc stay on. Of course if the PC is already off, reset does nothing.

EDIT, I have misread the 1st post, disregard anything I wrote.

Thanks for the advice, I can't find the information in my manual. Here's the page for my mobo if that's any help GIGABYTE - Motherboard - Socket 1155 - GA-Z68MA-D2H-B3 (rev. 1.0)

Badger906 suggested I start the machine with no power leads attached and the result was no different, the computer reset (and I couldn't turn it off without yanking the PSU cable out of the back!)

So you think this may be a case/mobo incompatibility problem? Interesting...

Hi,

The build I did this past weekend was with exactly the same motherboard and an Antec 100 case : I connected up exactly as the manual suggested without any problem. What case is this?

It's a Fractal Design Core 1000.

Well, I finally tested a different PSU and it solved the problem! I'm glad it's not the motherboard, at least.

Thanks for all your help everyone, really appreciate it.
