dreamcast whirring!?
 

while playing my game the DC has stared making a high pitched whirring sound through the speakers of my tv anyone else have or had this?
if so did you fix it?
if so please tell.

You're saying it started mid-game? :eek:

Just with particular games, or all the time?

as soon as game boots all games.

Maybe you have a broken cable between your DC and your TV, with bad ground.
Just be sure that you have no short-cut between Right or Left and Ground in the Cable. Clean the Plugs on the TV Side and the DC and the Cable on both sides.
Or just try a diffrent cable for you DC
Maybe that helps
