Hey everyone -- I was having a problem and finally decided I needed help..

I purchased a custom-built computer wayyy back probably about 10 years ago now.. At that time, it was one of the optimal setups for computer gaming. It wasn't until about a month ago that I decided to start using it again. I also attempted to clean up a lot of the useless files that I had accumulated way back when.. However, I just purchased a new set of speakers for my computer, and realized that I must have deleted my sound driver along the way.. My problem is my computer is not factory-assembled from a particular manufacturer and I have no way of remembering what sound card I had to being with.. Is there an easy way to figure this out without opening up my computer? And if so, what is the best way to go about reinstalling the drivers for the sound hardware.. Please help!!

Thanks in advance,
Will

Also, I was going to add that my graphics card is a Geforce 4 Ti 4200 -- if that helps at all...
