Hi m8, what did you get in the end?

RJC · 29 Jun 2010 at 18:38

Was it pre-overclocked.

Try checking all components & power connectors are firmly in place.

anything else apart from a green light?

fans spin?

could be something as simple as the power button on the case being faulty.

short out the two pins on the motherboard its wired to

what ever two pins on the motherboard the front panel power button goes too, put a needle nose pliers across it, or a piece of wire for a quick amount of time

Have you been into the Bios and changed everything to its default settings.

Biz.Kid09 · 29 Jun 2010 at 18:56

Cant get to bios

and ok so just touch both? In the manual its saying that the pwr switch goes to one pin so just quickly touch this with some tweezers or something?

RJC · 29 Jun 2010 at 18:56

Do any of the fans spin up & hard drives start.

cmndr_andi · 29 Jun 2010 at 18:56

Asus M3A78 Motherboard, Socket AM2+ ?

What PSU are you working with? Also, do you have any spare PSUs to hand so you can check the system with a different supply?

power switch should be two pins, unless its one pin that is shorted to ground for a moment

The power switch should be 2 pins, linked them across with tweezers.

Its the psu with the case and i have tried another one that i have from australia (tried it and it works with another old hp i have) and i still just got the green led on the mobo

Ok so just touch it with some tweezers yeh? that wont kill my system or anything if it doesnt work will it?

cmndr_andi · 29 Jun 2010 at 19:03

Do you have any details of the PSU that came with the case? There should be a sticker or two on the unit that should have its name and rating. Failing that, there should be a sticker that gives the power of the unit and the maximum power and current to the rails. Would you be able to tell use what it says.

Are you running the system with the integrated graphics at the moment or with the 8800GTS?

Also, as RJC asked, do the fans spin up now when you press the power button?

Edit: Is it possible to take a photo.

+1 this could really help us diagnose your problem

With only one pin that might not work, as it looking for signal to be returned.
Ie - one pin sends the signal when you press the start button it sends the signal back.

Biz.Kid09 · 29 Jun 2010 at 19:05

Well thats what it shows on the manual and on the board but in the manual it describes it as 2 pin but on the picture it just shows one.....Can download the manual if you want a look?
