I would Clean Reinstall - Factory OEM Windows 7
as I suggested in your other thread.
If this is the same version Windows 7 then it could be made to work. You first must reactivate at Control Panel>System>Change Product Key using the Product Key on COA sticker.
I'd also uninstall all Asus bloatware in Control Panel>Programs and Features and using Clean Up Factory Bloatware
, however why bother with cleaning up corrupting factory bloatware when you can clean reinstall and get the best possible install?
To connect to internet make sure the network driver
is installed in Device Manager. If not install it from the computer's Support Downloads webpage. Then connect to internet using the connection icon in bottom-right System tray. If this fails, rightclick on the icon to Troubleshoot Problems.
