Windows 95? I Remember Those Days. Soundblaster! Adlib! Wow

I had a problem with my computer. Out of the clear blue, the sound card disappeared from my hardware settings. After trying to get Windows to re-install it, I gave up Win95 consistently told me that the card was a Soundblaster, and I knew it wasn't. But I didn't know what kind it was, and the manuals that came with the computer didn't say. I called tech support, and they asked me what had been installed on the system since I bought it. 

"Microsoft Office, and Plus" I said.

They told me that was the problem. They told me I wasn't ever supposed to install anything on the machine except for what came with it originally. Then they told me to reformat my hard drive and re-install everything from the setup CD.

I asked to speak with this guy's supervisor, and he told me the same thing.
