Hi Janet...the e-Machines, el1300g-01 has onboard ethernet (meaning it's integrated into the motherboard) and so it will be a multi-step process. Additionally, this motherboard only has one expansion slot, PCI-
EXPRESS MINI and this means there can't be anything else in that slot.
Begin by backing up all your important data, preferably to an external drive. We all skip this step and at one point or another we all regret it.
Now, before shutting the PC down let's disable the built-in ethernet. Right click on My Computer (or This PC in Win81) and select PROPERTIES.
From the next screen (PROPERTIES) select Device Manager.
When you get to the device manager find the entry for network and (assuming this is the only network connection you have) after expanding the dropdowns
, right click on the appropriate device and select DISABLE:
No you can shut the computer down and disconnect all cables, most importantly, the power cable.
Remove the screws from the back of the machine and slide off the cover (see the eMachines support site for assistance).
Lay the tower on its side, and make sure the slot is empty it will look something like this:

Remove the punch-out by removing the screw and then the small metal cover (see arrow).
Inser the new card carefully into the slot on the printed circuit board while guiding its small metal tab into the bottom of the punch out. Make sure it's gently and firmly in place and then secure with a standard PC screw--either from teh punchout or one that came with the card.
Remplace the cover on the PC, reattach all the cables and turn it on.
When the eMachines logo flashes on the screen look in the lower left corncer and press whatever key it is for SETUP or BIOS (usually DEL, ESC or f12).
Using the the ARROW KEYS on the keyboard (the mouse will not work in this mode) go through the menus on screen to select networking. Here you will find a setting that will say ONBOARD LAN or ONBOARD ETHERNET. Select and disable this, and then press F10 to save and exit.
The PC will reboot and upon entering windows, you should get a discovered new hardware message and any drivers will install themselves*.
Connect the internet cable and you are good to go!
Hope this helps,

*If your new ethernet came with a disk of software, follow the instructions that came with it before troubleshiooting on the WIndwos side.
