Here's the deal. My computer took a dump so I'm using an old Dell my brother had laying around until I buy a new one. I had to replace the hard drive, CPU fan, ethernet card, CD/R, and I added some PC133 memory. Since I've had this thing, I haven't been able to hear anything. I bought a 5.1 soundcard yesterday and still nothing! Winamp won't even act like an MP3 is playing. Videos play without the sound as do games. I've gone over and over and over this thing but I can't figure it out! Any thoughts? Updating the drivers didn't work. A new soundcard didn't work. I just don't know.
