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 Disk Problems
Your hard disk should make a slight whirring sound when
operating properly. If the disk 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 disk is securely attached at both ends. If it is, your
hard disk may be defective.
If the hard disk makes excessive noise:
Turn off the system, open the system unit case, and
remove the hard disk power cable connector from the
hard disk. Then turn the system back on. If the noise
disappears, your hard disk may be defective.
If you have more than one hard disk, repeat the same
procedure for each disk.
