I just got the GTX 660 for my windows 7 and I went to a computer shop, they helped me put it in and install the drives because it was my first time. I get home start it up (all good) till is a blank screen and I see at the bottom right somthing like " This is not a legal windows system"
I restarted it two more times and that message was gone but about one minute after I signed in "screen enter power save mode" I move my mouse nothing. What's weirder is the the back USB's don't work for some reason. It works fine in power save mode so I deleted all the nividea drives and reinstalled the drives. Same thing happened. Help!
