a 10.2-cm (4-inch) clearance on all vented sides of the
computer and above the monitor to permit the required
airflow.

(some fans only operate when needed).

back to the system.

Add more memory. Some applications run in the
background and can be closed by right-clicking on their
corresponding icons in the task tray. To prevent these
applications from launching at startup, go to Start > All
Programs > Accessories > Run (Windows Vista and
Windows 7) and type msconfig. On the Startup tab
of the System Configuration Utility, clear applications
that you do not want to launch automatically.
