I have a new Desktop with Windows 7. After I start the computer and leave it running for a while, (10 to 15min), it will automatically revert to the password screen. Also it won't go to screen saver. I have the screensaver set to not require password after waking. Also I have my power settings set to high performance. Also i have my Nic card configured so that it isn't allowed to be turned off. Still happening all the time. Super frustrating.
