Click on Product Views, then on - M-Front Panel Connector

The plastic front of your eMachines is the Front Panel.

The area of contact pins on the motherboard, that the wires from the Front Panel go to, is the Front Panel header.
Sometimes abbreviated as F_PANEL, or FP1.

Looking at the motherboard installed in the computer case, the Front Panel header is at the Bottom/Right.

http://support.gateway.com/s/MOTHERBD/FIC/105554/105554mvr4.shtml

The above link shows the pinout, of the Front Panel header.
(Note* The Front Panel header may not be Orange in color)

It is the Second header over from the bottom/right side.
The pins are numbered.

Starting on the TOP row, from the RIGHT side going towards the LEFT;
Pins 10, 8, 6, 4, and 2

Starting on the BOTTOM row, from the RIGHT side going towards the LEFT;
Pins 9, 7, 5, 3, and 1.

A) Pins 1 and 3 are for the HarDDrive Activity LED light.
The LED light that blinks when the harddrive is in use, or active.

Pin 1 is for the Positive ( + ) wire.
If the LED is dim when operating, switch the wires around.

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


C) Pin 9 is for 5 Volt power. I believe if memory serves, that it is ONLY used by the factory.

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

E) Pins 6 and 8 are for the Power On switch.

F) Pin 10 is N/C. Not Connected.
(Note it states - Key
It shows you where the pins are. What order they should be by the missing pin)

The FIC K8MC51G motherboard;

1) Has a Socket 754 processor socket.
AMD processors fit in this processor socket,

http://en.wikipedia.org/wiki/Socket_754

2) The motherboard chipset is an Nvidia C51.
It is part of the GeForce 6 series, and more specifically, the GeForce 6100 series,

http://en.wikipedia.org/wiki/GeForce_6_Series#GeForce_6100_and_6150_series_chip_specifications

http://en.wikipedia.org/wiki/Comparison_of_Nvidia_graphics_processing_units#GeForce_6_.286xxx.29_series

Using this knowledge you can see what Processors are supported, and what Ram Memory is supported, (And how much)

AMD Sempron, or AMD Athlon 64 processors, with up to a 1000MHz Front Side Bus. (FSB) { That fit in a Socket 754 processor socket)

DDR Sdram ram memory that is 200MHz up to 400MHz.
(PC2100, or PC2700, {333MHz}, or PC3200)

{184-pins. 92 on each side}

OR,

DDR2 Sdram ram memory that is 400MegaHertz up to 1066MHz.
(PC2-3200, or PC2-4200/4300, or PC2-5300, or PC2-6400, or PC2-8500)

{240 pins. 120 on each side}

Your motherboard uses DDR Sdram. (184 pins. 92 on each side)

Maximum TOTAL Amount is 2GigaByte. (2GB)
Maximum Amount for EACH ram slot is 1GB.

3) Has one PCI-Express x16 slot for a PCI-Express graphics card.

The PCI-Express technology used for the motherboard is
PCI-Express 1.1

HOWEVER, you can use a PCI-Express graphics card that is based on the PCI-Express 2.0 technology.

PCI-Express 2.0 is Backward Compatible, with PCI-Express 1.1

You just will Not get the full capability of a PCI-Express 2.0 graphics card.
Will you notice? No

There is a 4-Pin Speaker connector that is not used by Gateway on the motherboard (right beside) the CMOS jumper settings (Pins).
The clear CMOS settings jumper block is right beside the speaker pins. You can use this jumper block to clear the CMOS RAM, which is powered by the onboard real-time clock button cell battery.
Pin 3 is indicated by the markings on the board.
Settings: Pins 1 and 2 covered = Normal Operation Pins 2 and 3 covered = Clear CMOS enabled.

Several things xopunkyxox.

No Signal means there is no Video Signal coming from the computer. The monitor is working fine.

eMachines computers are budget computers. This means they sell for a low price, but also have low quality hardware components used inside the computer.

There are two top issues for computer failure. These really affect an eMachines computer.

1) Power Supply
The PSU (Power Supply Unit) used is a low quality unit to begin with, in an eMachines.

2) Dirty computer.
Dirt, dust, etc., can bring a computer down to it's knees.

The eMachines W3118 desktop computer uses an FIC K8MC51G motherboard.
(First International Computers, inc)

(The eMachines W3118 desktop computer is a North American model)

FIC K8MC51G Specifications:

http://support.gateway.com/s/MOTHERBD/FIC/105554/105554sp25.shtml

http://www.fic.com.tw/product/motherboard/AMD/K8MC51G.aspx

The eMachines W3118 motherboard has a Socket 754 processor socket.
Comes with an AMD Sempron 3100+ processor.
(1.8GHz)

AMD processors run HOT. Keep the Heatsink, and Fan on top of the processor, CLEAN.
The Thermal Compound (Thermal Paste or Thermal Grease) that is in-between the top of the Processor's case, and the bottom of the Heatsink, can dry out over time.
The heat developed by the Processor when operating does this.

A Power Supply (SMPS) has two cooling features.
1) The internal fan that you can see by looking at the back of the Power Supply, (Back of computer)
2) Heatsinks used inside the Power Supply.

Example of an internal view of an average SMPS,

http://en.wikipedia.org/wiki/Switched-mode_power_supply

Click on the photo to the top right. In-between the letters B and C, and also C and D, are aluminum Heatsinks.
What looks to be finned rectangles arranged in a vertical strip.

When the fan's blades, center hub, and surrounding cage, (Shroud) are clogged with 'gunk', the cooling capacity of the Fan drops tremendously.

Same thing with the fins of the Heatsinks.

[Construction of an average Heatsink is a plate of metal with tall, thin fins protruding from it.
The plate of metal absorbs heat from whatever object it is placed against, and the tall, thin fins absorb heat from the plate of metal.

The fins then radiate the heat away. With a fan used in conjunction with a Heatsink, the fan pushes air in-between the fins, and around the fins. The air flow helps carry heat away]

Heat = Wasted Energy
The overheated Power Supply strains to keep up with the call for power, but eventually fails.
(Hardware components inside the Power Supply fail)

I'm willing to bet it's Power Supply failure.
Test the three main voltages from the Power Supply. (3.3 Volts, {Orange}, 5 Volts {Red}, and 12 Volts, {Yellow)

The next thing to be an inherent problem with an eMachine desktop computer, are the Electrolytic Capacitors on the motherboard.
Low quality capacitors are used.
(Radial Aluminum Electrolytic Capacitor)

Visual identification of bad capacitors, (Electrolytic),

http://www.capacitorlab.com/visible-failures/index.htm

[NOTE*
Not all bad Electrolytic Capacitors show visual signs of failure. Sometimes the Electrolytic Paste inside the capacitor dries up. No bulging case, or leakage will be present ]

Summary:
1) Computer unplugged from power, Anti-Static Precautions observed, clean the inside of the computer out.
2) Replace the Power Supply.

Also remove the Ram Memory modules, ('Stick'), and clean the gold plated contact pins on the ram memory module, with a pencil eraser.

http://en.wikipedia.org/wiki/File:Generic_DDR_Memory_%28Xytram%29.jpg

(You can click on the photo to enlarge)

Your eMachines W3110 uses DDR Sdram ram memory.
184 contact pins. 92 on Each side.

[It is DDR Sdram that operates at either 333MegaHertz {333MHz}, or 400MegaHertz. {400MHz}. Also know as PC2700 or PC3200, respectively]

Handle the ram memory by the body. Refrain from touching the contact pins.
The body of the ram memory is coated with a see-through protective plastic, which shields it from Static.

The pencil eraser is rubbed going Down the contact pin. Start at the top, and go down. If you are using the eraser on the end of a pencil, and not a solid eraser, refrain from letting the metal band touch the contact pins.

After you have cleaned each contact pin it may look as though you have not done very much.
I assure you have. Doesn't take much 'corrosion' on a gold plated surface.

Use air to remove the eraser dust before reinstalling the ram memory.
You can use a can of compressed air for computers, or air pressure from your mouth will be sufficient.

Use compressed air to clean out the ram memory slot/s on the motherboard also.

The On/Off switch is referred to as an ATX Power On switch.
Thought I would post that so it would make the switch simpler to search for.

This is one example of an ATX power on switch that I have found fits Many computers,

http://www.directron.com/atxswitch.html

The plastic button you push is the Power On Button assembly.
This plastic part can be heated with a hair dryer to soften the plastic, and easier removal of the defective Power On switch inside it.

{Hair dryer nozzle moved slowly back and forth on the Power On button assembly)

Usually there are two to three plastic tangs that protrude from the plastic housing, of the Power On button assembly.
These tangs are what hold the Power On switch in place.

After constant repeated heat from the inside of the computer, and due to age, the plastic becomes brittle. Breaks easily.
Heating the plastic should help prevent breakage.

Since the old Power On switch is going to hit the trash can anyway, you can also lower the entire assembly down in a bowl of fairly hot water. This to will help soften the plastic if a hair dryer is not available.

The new Power On switch has wires coming from it which connect to pins on the motherboard.
The plastic front of the computer is the Front Panel.

The area of pins on the motherboard, that the wires from the Front Panel connect to, is the Front Panel header.

It is the second connector of pins, over from the Right outside edge of the motherboard.

Two rows of pins.
5 across the Top, 4 across the Bottom.

The Pins across the Top are numbered Odd.
Starting from the Right side of the motherboard going towards the Left,
Pins 1, 3, 5, 7, and 9

The Pins across the Bottom are numbered Even.
Starting from the Right side of the motherboard going towards the Left,
Pins 2, 4, 6, and 8. There is NO Pin 10. Just a blank spot.


A) Pins 1 and 3 are for the Harddrive Activity LED light. (HDD LED)

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

C) Pin 9 is Not Connected. {Not used}

D) Pins 2 and 4 are for the Power On LED light.

If a Dual Color LED is used it connects to the header to the Right of the Front Panel Connector.

I think this is the correct link for your mobo:

http://www.fic.com.tw/download/other_products.aspx

could be a 'gray market' machine! i've run into this before- basically 'your motherboard/bios' doesn't exist- good luck! boot up should show what your bios version is, look for that, rather than your motherboard version!
'my computer'- 'properties'- should have your bios info on it. use that info to find updated 'flash', if it's available.
good luck!

if this is the correct Motherboard in case try the driver
