I refurb PC's to donate to Foster Children and this last PC I have gone through is a a PIII 800mhz Compaq Desktop. Right off the bat I found the Power supply to be bad so I replaced that with one I had sitting around. Everything else in the reinstall and all software went on with ease. All drivers where installed fine with no yellow question marks in the Device page. So my final test is always to make sure I have sound coming from the Green mini jack and in this case I do but when playing a music CD it plays it fast. Kind of sounds like your listing to the chipmunks playing Aerosmith songs (my lest disc is Aerosmith greatest hits) but it does the same on any disc i put in. So I replaced the CD drive with a Burner and still I get the same music speed. I even ripped the disc and it even plays back the ripped at the same fast speed. I'm not sure where to go now! It has it's built in sound so there is no card. Any Ideas what it could be?
