2. try goin to run

   typin this command

   msconfig

   n press ok

   n remove the tick from the progam that u suspect is the cam thing, n restart ur compuer,,

   n then when u turn it on again unstil it, if it wouldn’t turn off unplug the power supply until it turns of on it’s on,,

3. Press the POWER button for 4 seconds then the system will shutdown.

   Power on again and then press F8 after the vAio logo appears.

   A menu will display then, choose the "Restore to Good Configuration…blah..blah" something like this and press enter.

   It should work by now.

4. Try to perform a clean install of your operating system. However, it will erase everything you have in your system and put your laptop in it’s original factory condition.

   To perform a "clean install" of Vista, place your recovery disc into your cd/dvd drive but don’t close the drive yet. Restart your laptop and just before it boots up, close the drive. The system will recognize the cd in the drive and knows that it needs to reinstall the operating system.

   You mention that your laptop does not allow you to shutdown your system because of the software driver for the wrong webcam. Just try to force it to shutdown by pressing the power button so you can reinstall the operating system.
