Poor performance.

Cause Solution

Processor is too hot. 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 heat sink is installed properly.

Hard drive is full. Transfer data from the hard drive to create more space on

the hard drive.

Low on memory. Add more memory.

Hard drive fragmented. Defragment hard drive.

Program previously accessed did not release reserved

memory back to the system.

Restart the computer.

Virus resident on the hard drive. Run virus protection program.

Too many applications running. Windows 7:

1. Close unnecessary applications to free up memory.

2. Add more memory.

3. 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:

In Windows 7:

a. Go to Start > All Programs > Accessories > Run

b. Type msconfig, and then press Enter.

c. On the Startup tab of the System Configuration

Utility, clear applications that you do not want to

launch automatically, and the click OK.
