Ok this is a weird problem i've run into. Whenever i start the computer up before I go to the windows screen my computer makes a high pitch noise, when i start windows up the high pitch noise goes away and is replaced with a processing sound I guess you can call it. The weird thing is if I click back on my browser the sound will stop every time I click back. I also opened up Diablo II and in the start screen and lobby the sound would stop but as soon as I went into the game it would pick back up, but less noticeably. I'm hoping this is my cpu, which is an athlon 64x2 4200+.

There's no such thing as a processing sound. That might be the sound of the fans rotating inside. A high pitch noise is usually uttered by a dying PSU. Or maybe a busted cpu cooler fan. Could you give the specs/model of the PSU you're using?

It's an allied al-c400atx. I know it's not the fan because whenever i unplugged the fan, the sound stayed the same.

Must be the PSU. It's an unknown brand and its dying.

Cpu's dont make sounds. They have no moving parts.

err guys, I know for all of my systems, when in POST the fans turn on at absolute FULL and then dim down to normal after POST, and that older/crapier mobos have had fans that ran on full until OS hand off or something like that...

then again that psu seems like a no name and is dying.
