Okay, I just downloaded the Ethernet and wifi drivers into a CD. How do I add it or put it to use in my PC?
OK, you burned the file(s) that you downloaded, onto a CD? Just eject the CD (finalize if necessary), and then pop it into the new machine, click on the File Folder on the TaskBar (File Explorer), should show your CD/DVD/BR drive, then find the files on the disc, and then select/highlight them, right-click and select "copy", then on the left-hand pane of File Explorer, navigate to the Downloads directory, then right-click and select "paste".
Then for each file you transferred, double-click it. If it's a ZIP file, there should be an item in the File Explorer window, under Extract, there should be an Extract All... and then select that, let it extract to the default named sub-directory, and then find SETUP.EXE, or AUTOPLAY.EXE if there's no SETUP.EXE (rare), and double-click it, in the extracted files directory. It should start the driver setup.
Do this for each of the drivers.
Start with the chipset drivers, then the Network drivers, then Video drivers, then the Sound drivers, then any Utilities that need to be installed too.
