|Did you power it off completely? |
Try this maybe. Turn it off either by menu if works or with the power button. May have to hold power button for a minute or so. Then remove ac plug, then press power button a few times.
Return ac plug and try again, it should power up normally. If not then boot to the W7 dvd and use the repair features.
1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.
