Solution
Transfer data from the hard drive to create more space on the
hard drive.
Add more memory.
Defragment hard drive.

1.
Close unnecessary applications to free up memory.
2. 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 >
Run and type msconfig. On the Startup tab of the
System Configuration Utility, clear applications that you
do not want to launch automatically.
1. Lower the display resolution for the current application or
consult the documentation that came with the application
for suggestions on how to improve performance by
adjusting parameters in the application.
2. Add more memory.
3.
Upgrade the graphics solution.
Restart the computer.
Solution
1. Ensure that the computer air vents are not blocked and
the processor cooling fan is running.
2. Open hood, press power button, and see if the processor
fan spins. If the processor fan is not spinning, make sure
the fan's cable is plugged onto the system board header.
3.
If fan is plugged in, but is not spinning, then replace the
heatsink/fan assembly.
