System Unit Problems
The fan inside the system unit should make a low, steady sound
when operating properly.
If the fan is totally silent:
Check that the system power cord is securely attached to the
back of the system unit and to a power outlet. Verify that the
outlet has power.
If possible, substitute another power cord that is in good
working order. If the substitute works, replace your power
cord.
If the fan makes excessive noise:
Turn off the system, open the system unit case, and inspect the
fan for any obstructions.
Turn on the system and listen closely to the fan. If the noise
comes from inside the fan housing, your power supply may
need replacement.
Hard Drive Problems
Your hard drive should make a slight whirring sound when operating
properly.
If the drive is totally silent:
Turn off the system, open the system unit case, and check that
the power cable between the power supply and the hard drive
is securely attached at both ends. If it is, your hard drive may
be defective.
If the hard drive makes excessive noise:
Turn off the system, open the system unit case, and remove the
hard drive power cable connector from the hard drive. Then
turn the system back on. If the noise disappears, your hard
drive may be defective.
If you have more than one hard drive, repeat the same
procedure for each drive.
