BSOD whenever I leave the laptop idle for a 2+ hours.

Windows 7 Home Premium 64bit on Lenovo laptop running at 1.90GHz.

Power options set on high performance.
Sleeps when I close the lid.

The BSOD occurs whether I close the top to put it to sleep or just leave it open to continue running.

The BSOD: Driver Power State Failure

I've followed posting instructions and uploaded the zip file.

Thanks!

Welcome to Seven Forums.

The BSOD seems to be caused by:

Code:

S6000KNT.sys                Mon Sep 13 09:18:58 2010 (4C8D9822)
Chicony Webcam Driver

Update to the latest version available. If that does not help, unplug the device and remove any related software and see if that helps.

• Uninstall DAEMON Tools and any Alcohol % software. It uses a driver called sptd.sys which is known to cause BSODs in Windows 7. Uninstall the software using Add/Remove Programs. Reboot the system. Once the program is uninstalled, run sptd.sys uninstaller to remove the driver from your system.

As an alternative, many people recommend the use of Total Mounter or Magic ISO

• Keep less stuff at the start-up. Only anti-virus, this helps avoid driver conflicts and improves time to log in to windows.
