Troubleshooting
This section provides solutions to some common problems
which you may encounter when using the ASUS Desktop PC.
Contact the ASUS technical support if the problem still exists
after you have performed the troubleshooting solutions.
What can I do if my Desktop PC cannot be powered on?
Check if the power LED on the front panel lights up. It does not
light up if no power is supplied to the system.
• Check if the power cord is plugged in.
• When you use an extension cord or a voltage regulator, check
if you have plugged it into a power outlet and switched it on.
What can I do if my Desktop PC cannot enter the operating
system?
• Check if your peripheral devices are compatible with the
system. For example, some USB storage devices are with
different disk drive structure and enter the sleep mode easily.
If the above steps do not solve the problem, contact your retailer
or perform system recovery using the supplied Recovery DVD.
Why is it that I cannot hear anything from my speakers/
headphones?
Check if the volume icon in the Windows® taskbar is set to the
Mute mode . If so, double-click this icon to display the
volume bar, and then deselect the
Mute
checkbox to disable the
Mute
mode .
You will lose all your data during the system recovery. Ensure
that you make a backup of it before recovering the system.
Why is it that a CD/DVD cannot be read from or written to?
• Check if you use a disc compatible with the optical drive.
• Check if you insert the disc properly or if there is any scratch
on the disc.
