Installing Driver

I always find trouble shooting a computer as a challange for me. Specially if there is some non hardware problem i wanted to work for it untill i solve it. Today the problem was to install the audio driver. The system doesnt have any written specifications. Browsed for some free tools like Everst, Hardware Scanner and some other i dont even remember their name, by which you can imagine how many tools i used to find the correct name. But finnally i found Sisoftware Sandra lite which didnt gave me the name of the audio hardware but i dig it out, confused let me explain. After i install this kit, i wanted to see audio device specification but funniest thing is the button which displays audio specs was disabled because i havent installed the driver. Then i went through the main board specs there i found audio device model as C3DX never heard of it. It belongs to C media Electronic. Thank god finally i made it.
