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.
