Solution
1. Check the F10 BIOS settings to make sure the internal
system speaker is not muted (this setting does not affect
the external speakers).
2. Make sure the external speakers are properly connected
and powered on and that the speakers' volume control is
set correctly.
3. Use the system volume control available in the operating
system to make sure the speakers are not muted or to
increase the volume.
Ensure that the device is connected to the correct jack on the
rear of the computer.
Solution
1. Make sure airflow to the computer is not blocked. Leave
a 10.2-cm (4-inch) clearance on all vented sides of the
computer and above the monitor to permit the required
airflow.
2. Make sure fans are connected and working properly
(some fans only operate when needed).
3. Make sure the processor heatsink is installed properly.
Transfer data from the hard drive to create more space on the
hard drive.
Add more memory.
Defragment hard drive.
Restart the computer.
Run virus protection program.
1. Close unnecessary applications to free up 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 > Run (Windows XP) or Start >
Accessories > Run (Windows Vista) and type
msconfig. On the Startup tab of the System
Configuration Utility, uncheck applications that you do not
want to launch automatically.
CAUTION: Do not prevent applications from launching
at startup that are required for proper system operation.
2. Add more memory.
