NOT STARTING UP

power connecter has totally 9 pins on the board but actually we have to use only 8 pins please refer the attached image


if you have further any doubts post me

Pin Configuration = Pinout

The Front plastic panel of the computer is the Front Panel.
The area of pins on the motherboard that the cables (Wires) go to, is the Front Panel header.
Front Panel header pinout.

The motherboard used in an eMachines T2672 desktop computer is an FIC AU31 motherboard.
Made by First International Computers (Inc.) for eMachines.

http://www.e4allupgraders.info/dir1/motherboards/socketa/au31.shtml

Orient the motherboard like it is in the photo, so we are both looking at it in the same direction.
{Processor to the top, Ram memory slots to the right, white PCI slots to the bottom. The way it sits in the computer case}

The Front Panel header, is a small black rectangular block that sits horizontally, at the far right bottom corner.

It has two rows of pins.
4 across the top, and 5 across the bottom.

(The small rectangular block above it, is for connecting a Power On LED light that has 3 wires. More on this in a moment)

The pins are numbered.
The pins are numbered Evenly across the top, and Odd across the bottom.

Starting from the Left side going across to the Right, on the Top row;
Pins 2, 4, 6, and 8.
There is No Pin 10.

Starting from the Left side going across to the Right, on the Bottom row;
Pins 1, 3, 5, 7, and 9.

A) Pins 1 and 3 are for the HarDDrive activity LED light. (HDD LED)
Pin 1 is for the Positive wire ( + )
(If the LED light is dim when operating, switch the wires around)

B) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used. (Reset button)

C) Pin 9 is Not Used. (NC. No Connection)

D) Pins 2 and 4 are for the Power On LED light, IF it is a 2 wire LED light.
Pin 2 is for the Positive ( + ) wire.
(If the LED light is dim, switch the wires around)

If the Power On LED light has 3 wires:
Use the Power On header above the Front Panel header.
This rectangular block has 3 pins.

Starting from the Left side going to the Right; Pins 1 , 2, and 3.
Pin 1 is for the Positive wire.
Pins 2 and 3 are Ground wires.

E) Pins 6 and 8 are for the Power On switch. (Power On button plastic assembly has an ATX power on switch inside it)

This is a link to a free motherboard manual, for the FIC AU31 motherboard. It is in Zipped file form.
(A Zipped file is a compressed file. It is used for one, to send a large file over the internet)

If you do not know how to unzip a file, post in a Comment, and I'll lead you step by step.

[ P.S.
The motherboard chipset is an Nvidia Crush 18G + MCP AGP
It is an Nvidia Force 2 chipset,

http://en.wikipedia.org/wiki/Comparison_of_Nvidia_chipsets#nForce2

Supports Processors that are AMD, and fit in a Socket A processor socket.
(Socket A is also known as Socket 462)

Supports AMD processors that have either a 200MegaHertz Front Side Bus, or a 266MHz FSB, or a 333MHz FSB.

AMD Athlon XP processors with either a 266MHz FSB, or 333MHz FSB.
From the 1500+ model up to the 2800+ model.

AMD Duron processors with a 200MHz FSB.
From the 800MHz to the 1.3GHz models

(AMD Athlon XP is the top of the line. Then it's Duron, then Sempron.
A Sempron processor has half of the L2 cache that a comparable Athlon XP does)

Ram Memory is DDR Sdram at either 200MHz, or 266MHz, or 333MHz, or 400MHz.
Depends on the Processor used.

(Ram Memory typically operates at half of the frequency rate ('Speed') that the Processor does.
If the processor's FSB is 333MHz, you can use 400MHz DDR Sdram. {PC3200}

Confusing I know.
DDR Sdram is 'double-pumped'. It is actually 200MHz for PC3200.
This is close to half of 333MHz.

Processor has an FSB of 266MHz? Ram memory used will be 266MHz. Remember, it is actually 133MHz for the ram memory. (PC2100)

Need an AMD Athlon processor?
I found this place years ago. Not advertising for them. Just computer geeks sticking together, and sharing information. (I have bought a motherboard from them, and it works fine),

micha219, the eMachines W2925 desktop computer uses an FIC motherboard.
First International Computer { Inc }
The Model Number of the FIC motherboard is VC37.
FIC VC37.

Disregard the following if you are aware:
The plastic front of your computer is the Front Panel.
The area on the Motherboard that the cables (Wires) from the Front Panel connect to, is the Front Panel header.

Processor to the Top, Ram Memory slots to the Right, the Front panel header is in the Bottom Right corner.

It is a rectangular shape with two columns of pins.
The length goes up, and down on the motherboard.

The pins on the Right side of the Front Panel header are numbered Odd.
The pins on the Left side of the Front Panel header are numbered Even.

There are 4 pins on the Left side.
There are 5 pins on the Right side.

Starting at the Bottom on the Right side going Up;
Pins 1, 3, 5, 7, and 9.

Starting at the Bottom on the Left side going Up;
Pins 2, 4, 6, and 8.

A) Pins 2 and 4 are for the Power On LED light.
(If after connecting the LED light is dim, reverse the wires)

B) Pins 6 and 8 are for the Power On switch. (Power On button)

C) Pins 1 and 3 are for the HarDDrive Activity LED light.

D) Pins 5 and 7 are for the Reset switch. (Reset button. IF used)

Pin 9 is NC. Not connected

YOU MAY HAVE TO CALL HP /COMPAQ TO SEE IF YOU HAVE THE RIGHT MOTHER BOARD FOR THAT PC

TWO things.

1.Power supply is going bad.
2.Electrolytic Capacitors on motherboard are bad.

Power Supply:
A weak power supply that has 1 or more capacitors that are failing, will have enough power to light all lights, spin fans, and even spin the harddrive in some cases.

But doesn't have enough power to make the Processor run.

A.ALL the lights for your computer use less than 1 Watt.
B.EACH fan uses 2 to 3 Watts.
C.A harddrive spinning in an endless loop uses about 2 Watts.

A Processor will use 55 to 125 Watts! Depends on what processor it is.

Capacitors going bad in a power supply will make a weak Voltage Rail.

Bad capacitors on motherboard:
Capacitors used around the Processor are Voltage Regulators. A Processor must have a Clean, Steady supply of DC Voltage. Processors have a VERY small tolerance range. Too little voltage they don't turn on or stay on. Too much they can burn up.

For information purposes, this link gives you more info on visual signs of failure for capacitors, on a motherboard.
(It is for information so that you may have it to diagnose your motherboard's capacitors. It is not advise to replace them from me.

CAUTION!!

It is - NEVER - advisable to open a computer power supply to work on it, Unless you have technical expertise at this.

Why?

Because those Electrolytic Capacitors are designed to hold a charge, and then suddenly release it. (Camera flash is a good example of capacitors being used)

They can hold a charge for Weeks, sometimes Months, after the power supply is unplugged from power!!

Should you open the power supply, and your fingers touch both terminals of a capacitor, it Can, and Will, release it's charge to YOU!

Should your fingers complete a circuit that, one or more, capacitors are in, they will release their charge to YOU!

Result? BAD shock to FATAL!

We at FixYa want you to be SAFE!

I just wanted you to have all information I can give you. A tech has to PROPERLY discharge the capacitors, before working on a component that contains them. I will Not detail out this procedure here.

Preferred method is to use a known, good power supply, put it in the computer, and see if this is the problem.

(BIOS doesn't come up.

Has nothing to do with the harddrive, therefore it isn't a bad harddrive, nor corrupted files in the Operating System.

BIOS is the first program to run on a computer. It's 64MB's in size. Very small. After BIOS recognizes all devices, and does a Ram Memory count, it turns the Processor on, and hands the computer over to the Operating System.

Your computer isn't even getting to BIOS, so it isn't bad Ram Memory sticks, nor bad Processor, nor Operating System. It's not enough power, or failing capacitors on the motherboard)

Open the cover. Put out the RAM and insert again. Do the same with Processor. Recheck all the outer connections. It may solve the problem. ([email protected])

hi most of motherboard power on pin is 6 and 8 just short these two pins once if mothernoard starts it;s giving display else check ram or smps otherwise motherboard faulty.

have u check ur memory?... ur videocard and powersupply...thats the main problem of pc if it has no display....just try it one by one...hope it can help u

Yes, had exactly the same problem earlier this week, the bios chip may be faulty, as you know all other components work, so it's down to the motherboard and a replacement is required
