I installed the voltage regulator, and the sound on my hifi is much better now, computer kept crashin though, I don't know why but I imagined the problem would be too low voltage, but the indicator on the regulator says that I am getting too high voltage ( not always I saw it go on a couple of times). anyway, after a lot of work and fiddling around, it turns out it's a problem with quad core cpus and the motherboard I am using ( cheap motherboard ASRock 4corequad-sata2), all I had to do to get it to run without crashing was change a value in the bios. I just got me a new motherboard today, will install it tonight, and install 64bit intrepid. Thanks for your support!
