VGN AR21S high pitch noise from CPU

VGN AR21S high pitch noise from CPU

Hello Everyone,

I am a brand new poster and was hoping someone can help.

When I load applications such as Windows Media Player, Camera Utility, Windows Media Center and others, I get a high pitch noise coming from the middle of the keyboard.

The noise is also present when I am viewing websites which have flash animated graphics on them. Those without such as Google don't cause any noise at all.

I have sent it to Sony aroung 6 times now but they haven't been able to assertain any problems and just send it back saying the laptop is operating within spec.

I am preety sure it's the CPU because I have used a programme to slow it down to like 50 percent and when I test the above situations the noise is very faint or no longer there. But this option is no good to me as it slows my laptop down a lot.

When windows is loaded and it's just idle it's fine, no noise at all. When I open other applications such as Word e.t.c it's fine also.

Can anyone help?
