    I really appreciate the help you guys gave me. I ended up tearing the case apart and connected all the power cables and still no-go so I guess I have a bad MTB since I know the PS works just fine. Thanks again.

    Thanks. I downloaded the user manual (posted in a related link...) and found the two pins that turn the supply on. Thanks for your help.

No, don't automatically assume the mobo is broken. Look closely at all the pins. There should be a 4x2 rectangle of pins, maybe coloured. They'll say things like 'PWR-SWTCH' and 'çPU-LIGHT'
Connect those up, and your mobo manual should have specific details on what goes where.

No power from gigabyte motherboard


Nope

Just basic diagnostic tools

First thing to check IS the Power Supply.
Then the diagnosis goes on.

So far all you have told me is an assumption. You ASSUME the Power Supply is OK.

Don't.

1) If ALL of the LED's were on at once, they would use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor can draw from 51 to 125 Watts of power.
Just depends on what Processor it is,

By having JUST the CPU on the motherboard, and the fan on the Power Supply doesn't work; you have just PROVED that.

Do you have a multimeter?
An economical one can be purchased for as little as $5 to $12.
Available in a multitude of stores.

There are 3 main voltages to check. Check while PSU is plugged into mobo. (Power Supply Unit; MOtherBOard)

A) 3.3 Volts
B) 5 Volts
C) 12 Volts
All are DC Voltage. (Dotted line over a solid line for Multimeter)

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

The Orange wires are 3.3 Volts
The Red wires are 5 Volts
The Yellow wires are 12 Volts. All are DC Voltage. (DCV)

The 24-pin ATX main power cable is left plugged into the mobo.
The BACK of the power cable's connector; is where the wires go in.

Power Supply unplugged from power; a straightened out paperclip is inserted down into the socket hole with an Orange wire in it.
The paperclip slides down alongside the insulation of the Orange wire, and touches a metal female terminal.

Every wire going into the 24-pin ATX main power cable's connector, ends in a Molex female metal terminal,

http://www.molex.com/molex/products/datasheet.jsp?part=active/0002081202_CRIMP_TERMINALS.xml&channel=Products&Lang=en-US

The brass tip openings can be seen, in the Playtool link's middle photo. (Tip openings; Front. Paperclip touches Back)
MUST touch that metal terminal.

Another paperclip is slid down into ANY socket hole, with a Black wires in it.
ALL Black wires are Ground wires.

Making sure the paperclip jumper wires, are of the correct length by cutting; there is no way they will accidentally touch each other.

Positive (Red) probe lead of multimeter to Orange wire paperclip;
Negative (Black) probe lead of multimeter to Black wire paperclip.
You should read 3.3 Volts (DC)

Do the same for the Red - 5 Volt wire. Red wire and Black wire.
12 Volt - Yellow wire and Black wire.

On another note;
Did you just recently mount the mobo to the computer case?
Did you use metal Standoff's, or plastic Spacers?
(Standoff - Hex shaped brass piece, usually 1/2 inch tall; and with a threaded hole on one end, and a threaded shaft on the other)

The Support Plate can be a separate metal plate; or is an integral part of the computer case.

IF, there is a Standoff on the Support Plate, that is NOT lined up to a motherboard mounting hole, it can touch exposed solder joints on the bottom of the motherboard.

This will short circuit the motherboard. MOST of the time when the 'offending' Standoff is removed; everything is OK.

Power front panel conectors on acer 915m08


This Foxconn 915M08-G-8KS motherboard made for Acer Veriton desktop computers?

http://www.sella.co.nz/general/computers/components/motherboards/other-motherboards/b1jnj6/

Do not know what the Front Panel header pinout is.

(Front plastic part of computer tower is the Front Panel.
Area of contact pins on the motherboard, that the wires (Cables) from the Front Panel connect to, is the Front Panel header )

CAN see by clicking on - View full size image - that the Front Panel header is to the Top Left corner of the motherboard, by the CMOS battery.
(View of mobo is upside down, in relation to how it actually sits in the computer tower case)

Shows me it is just the normal two rows of contact pins used in a LOT of desktop computer mobo's. (MOtherBOard)

If it were I, I would use one of the LED lights connected to two wires, and touch across each two sets of pins.

Looking at the motherboard as it sits in the computer case, there is a row of pins on Top, and a row of pins on Bottom.

In your mind start at the LEFT side of the pins at the TOP.
Number them from Left to Right.
Example, Pins 1, 3, 5, 7, and 9.

Now number the pins on the Bottom, from Left to Right,
Pins 2, 4, 6, 8, and 10.

Computer plugged into power, touch the two wires of the LED light, to Pins 1 and 2.
Computer doesn't start? (Power Supply turns on)
Go to the next set of pins.

I am willing to bet Pins 5 and 6 turn the Power Supply on.
No? Keep experimenting.

What will happen if you touch the WRONG pins?
N-O-T-H-I-N-G
You will NOT hurt the motherboard.

When you get to the correct pins, the Power Supply will turn on.
These pins are for the Power On switch.

Now go back through the pins with the Power Supply on, but DO NOT touch the pins that turned the Power Supply on.

When the LED light STAYS on, you have the pins for the Power On LED light.

If the LED light BLINKS, you have the HarDDrive activity LED light.

If Windows starts to load, and you touch the Restart switch pins, the computer will restart over again, and Windows will load again.

(IF this computer has a Restart switch. I do NOT use one, even for the older computers. Just press CTRL, ALT, and DELete keys at the SAME TIME, to restart the computer, or use the Task Manager option)

One pin left all by itself? That is for 5 Volts, and only used by the factory. Leave it unconnected.

There may also be a blank spot on the Front Panel header, where it looks like a pin is missing. This is the KEY pin, and is not used.
It is just to orient where the other pins are.

Worried about getting shocked?
There may be a small spark, as you connect the wires, I will gramnt you that.
But the voltage is 5 VOLTS DC.
In comparison two D cell flashlight batteries produce 3 VOLTS DC.

The harmful AC voltage is contained in the metal enclosure, of the Power Supply. Can't get you unless you pour water on it close up, or stick a metal rod through one of the ventilation holes, in the Power Supply enclosure.

joecoolvette

By the by. You could be a lot of people's hero, if you came back, and posted the pins for what they do. Post in a Comment.

How do I plug the Power Button wire into the motherboard?


Printed on the MB
HD LED +1 -3
PWR LED +2 -4
RESET 5- 7+ (Why the changed order? & there's no reset button on this computer.)
PWR ON +6 -8

There are nine pins with a little triangle pointing at one and a 2 next to another.
The pins on the MB look like this:

2ndpin
. . . .
. . . . .
1st pin


Found some info on the 506GR. Unfortunately Gateway is keeping the service manual a big secret.

This will help. Thanks please keep updated. please do rate the solution positively .Thank you for using Fixya

Ok, test the power button pins. First disconnect any power source to the computer. Then, find the power pins on your motherboard (the one that your case's power button connects to. Usually two wires, one red and the other black). Grab a jumper a connect it to those two pins, they usually have the letters "pwr" or "power" printed next to them. Then, once you've done this, with the jumper connected, connect the power cord to your power supply. It should turn on by it self. If it does, then the problem is the power button. If it does not do it, then the problem is the motherboard. Good luck.

by mb pwr connector do you mean the swich on the pc case that you press to turn it on or do you mean the large block connector form the power supply ?

If you mean the case switch then you have a faulty one that is sendinga constant signal and locking up the power supply
