Possible Solution
Ensure that the device is connected to
the correct jack on the rear of the
computer. 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./

airflow.
2. Ensure the fans are connected
and working properly (some fans
only operate when needed).
3. Ensure 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.

how to improve performance by
adjusting parameters in the
application.
2. Add more memory.
3. Upgrade the graphics solution.
