Table D-1Solving General Problems (continued)

There is no sound or sound volume is too low.

Cause	Solution
System volume may be set low or muted.	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.

The audio device may be connected to the wrong jack on the rear of the workstation or the jack has been retasked to perform a different function.

Ensure that the device is connected to the correct jack on the rear of the workstation. If the correct jack is being used and the problem persists, the jack may have been retasked to perform a function that is different from the default function. Open the Realtek control panel by clicking the Realtek HD Audio Manager icon in the task tray or the Realtek entry in the operating system's Control Panel and set the jack to the desired function.

Poor performance is experienced.

		workstation 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.

Virus resident on the hard drive.	Run virus protection program.
Too many applications running.	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 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.
