Your better off with installed as it may effect other parts of the network. If anything just click repair but it sounds like it's already installed if it's saying that.i dont use Ethernet tho anyways so i dont need it,.?
Try uninstalling the driver first.and how about the message that i got when i rebooted after installing the audio driver saying that it needs to be 64 bit dude
Can you download and run this app. We often use it to get information for blue screens but it collects data on many things and might be handy in providing a clue as to what is going on.booted pc after installing those drivers you asked of kemical, still restarted on its own
