Use the edit feature on the above post and remove your email address unless you enjoy getting slammed.

Look in device manager, if your NIC shows a warning then tell device manager to uninstall it, download the latest drivers for it for your machine from the machine manufacturer's website and install that. Then restart the machine to fully detect and install it with the new driver.
If it does not show a problem then it might be an infection so run Malwarebytes (if needed download on another machine and transfer the installer with a flash drive), and run it. Remove all it finds and try again.

You have to be a little bit crazy to keep you from going insane.

On both bad and good computers run the command line command ipconfig /all

Compare the two.

Also look at the command nslookup
On both of them they should return an ip address. If you believe the dns is the issue alone based on the result of ipconfig then correct the dns ip in the network card settings or see why you don't get it automatically from dhcp.
