I have always built my own rigs except for this one a gateway 7020 which has a phenom 9600 nvidia 8800gt 3 gigs of ram 500 gig ata hard drive 8 usb ports tv tuner realtek hd sound and is so quiet except for the hard drive making noise thru my speakers.The speakers are not next to the computer I have the latest drivers so I am at a loss what is causing this.I am using vista 32 bit and I must say this is the fastest loading and shutting down computer I have ever owned something like 45 seconds and this shocks me from some of the posts I have been reading so back to the noise thru my speakers.....any ideas Thanks in advance.Great site by the way as I have been a lurker for a month.I will add some more dribble as vista gave me a 5.9 score.
