Hi,
Am a complete computer novice and need help.

I have a computer brought from 'Tiny' many moons ago (serial number-pw221388). I have done a restore and lost all sound from my speakers.
I have looked in 'sounds and audio devices properties' and everything is greyed out.
I have gone to 'add hardware' and got the message 'the hardware was not installed because the wizard cannot find the neccesary software'
I've clicked on 'properties' and it says 'the driver for this device are not installed (code 28).
My device information is:
Multimedia Audio Controller (Unknown)
Chip: Silicon Integrated Systems (SiS) SiS7012 Sound Codec Detail
Chip
SiS7012 Sound Codec
Chip Vendor
Silicon Integrated Systems (SiS)
Device
Multimedia Audio Controller
OEM Device
MS-6524 mainboard
OEM Vender
Micro-Star International Co Ltd (MSI)
PnplD
VEN_1039&DEV_7012&SUBSYS_52401462&REV_A0
God knows if you need this or what it means.
Please somebody help.
Many thanks in advance.
