Emachines W3050 THE ETHERNET PORT IS NOT WORKING

I assume you have a bad internal ethernet port and are looking to add an internal board..
Manual is here:
eMachines T3265 Manual

assuming you have a free pci slot, these will work:

Check the bios and see if it listed there. If it is not, replace the drive.

• Verify in BIOS the devices are enabled
  
• Verify in device manager there are no driver problems and the devices are not disabled
• Open the case and verify the cables for the front ports are plugged in all the way

Sounds like the integrated ethernet port has gone bad. You can install a new ethernet card in one of the PCI expantion slots. Then plug the ethernet into the new card, this should take care of the problem. You can not repair a bad integrated ethernet port.

Absolutely!

The Ethernet port on your eMachines is part of the motherboard.
It is attached directly to the motherboard.

The eMachines T3626 Desktop PC, is supposed to use an
ECS MCP61-P (AM2) motherboard. (Cannot verify)
(Elitegroup Computer Systems. (AM2) refers to the processor socket )

(Also scroll down for a larger photo of the motherboard )

The Ethernet port is in the group signified by the letter A, on the left.
The group signified by the letter A, is in the I/O area.

Input/Output area. This is where Input, and Output devices are attached, TO the motherboard. (Using the motherboard's chipset)

Now look down the motherboard, to the two long white slots.
These are PCI slots. Signified by the letter I ( i )
If one of these slots is not being used, plug in an Ethernet Card, that is PCI.

If both of these PCI slots are being used, use the small white slot above them, signified by the letter H.

This is a PCI-Express x1 slot. If it is available, use it.
Use an Ethernet Card designed to fit, in a PCI-Express x1 slot.

[ Note*
The PCI-Express x16 slot that you have, (Orange in color, above the white PCI-Express x1 slot), is for a graphics card.

It is ONLY for a graphics card.
The PCI-Express x1 slot is NOT used for a graphics card ]

You don't buy an ethernet port, you buy a new PCI LAN card hat you can find in every IT shop for $10.

Go into bios and be sure the unit is set to boot to the DC/DVD when you boot up the unit.
clean the disk with windex - it helps to make it easier to read
