Summary: Not a happy camper. I bought this from Asus through Amazon. From almost day one my mouse would freeze for 10 seconds or longer, if it got to be a minute or more then I would have to force a shut down. Over these last 6 months since buying it in March. I would get blue screens, popups saying that the Nvidia graphic card clock was hesitating then would proceed. I took it to a computer shop. They couldn't make it do it. Ha!
