My 3640 monitor just started making a whining sound like a bearing
in a fan is about to self destruct.  Its coming from the cpu (local q
makes it quiet) and the character of the noise changes after I cause the 
machine to beep.  Powercycling did nothing so I suspect some hardware 
is going bad.  Anyone have pointers to which board might be the culprit?  

thanks

Keith
