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.
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.
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 (Microsoft Windows XP) or Start > All
Programs > Accessories > Run (Microsoft 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.
