High-pitched noise

C

Cape Cod

After I replaced the power supply unit to my computer, the built-in
sound card of A7M266 board started making high pitched noise.
Interestingly, it disappears when Windows XP is loaded but not with
linux os. Any suggestion short of returning the power supply will be
appreciated.

Maybe this is actually due to the refresh rate of your monitor rather than
the computer power supply?? Is your refresh rate under Linux different
than under XP? What about before the new power supply? Were you booting
between Linux and XP with the same refresh rates back then? If so,
disregard my idea. If you do think it's the PS than why not just return
it? It's not a difficult part to revove and replace.
