Im new here...

The story is, i erased the driver for the sound card!! Stupid me!! Its my office computer and i was trying to clean the junks inside. I remember erasing a realtek software (it looks like winamp). After that, i cant hear nothing!!! *GRRRR* I check the sound driver and its empty!?!

Ok... i dont even know what mother board this computer has. I can see the sound card is build into the motherboard. So, I took some pix of the computer. I just need help in identifying the motherboard and which driver i should look for the sound card??

Or maybe there is another way of detecting the sound card? Any help would be appreciated... Thanx in advance...
