This happened when I was on holidays in spain and found me coding the whole day instead of going to the beach... ...and every night when hundreds of lines of code are running through my brain... ...and everytime I look through the screen or elsewehere like a zombie, just thinking of the next piece of code to write... But i feel fine ;)

the funny thing is that the installation takes minutes to complete...only to copy 2 or 3 files from one end to another :D this is my personal *WOW* experience... :)

hi, i have this problem too. in fact it source are a: fan controller's manual volume control wich produces "flanger" noise wich is finally send out by my tuner AND b: the voltage converters.... i even hear it when the pc is idle (the volume control thing). i assume its a whistling sound wich occurs on your pc. thats the noise wich is often produced by these voltage converters. try to locate them and listen... but. hey...even if you are able to locate the noise source you have to replace the mobo to (propably) fix it.
