What should I do if Windows operating conditions become unstable?

Close all running software applications, and then reboot your VAIO computer.
If you cannot reboot the computer, press and hold down the(Power) button on the computer for more than four seconds to turn it off. When the computer is turned off, the power indicator is off. If the power indicator of the computer blinks orange while rebooting (from sleep mode), release the
(Power) button then press and hold it down for more than four seconds again to turn it off. Take note that this procedure may render created or edited files unusable.
