High pitch noise on Notebook when Fan is on

\015 On my Compaq V2000 notebook, when the fan goes on, there is a high pitch buzzing noise that also goes on simultaneous with the fan. When the fan turns off, the noise goes away. I noticed this noise after I manually turned off several of my start-up applications, so I thought it was related to one of the apps that I turned off. But, when I turned all of my apps back on, the noise persisted. Please assist.\015
