Question: What's the best site to diagnose computer noise? There is a metal box inside the computer where the power cord plugs in. The fan there (or something) has developed a loud whine. Sometimes it is louder than others. 1) What is it? 2) Is it a problem? 3) Can that be repaired or replaced?\nThe Computer is a hp pavillion and two years old, but very constant usage.

Answer: Sounds like your power supply. Based on constant usage you may need a new supply which can be purchsed for around 30 dollars.\n\nHow often do you clean the fan area by the power supply can make a difference. Dust may have developed there and got into the vent for the power supply.  They are relitively easy to replace.
