Ako ti se da, napravi jednu čistu instalaciju Windowsa, ali s drugog medija. Drivere instaliraj ovim redom:
1. DirectX 9 (ako ne stavljaš SP2)
2. reset
3. chipset driver
4. reset
5. WDM driver za grafu > Display Driver za grafu (Jelc

)
6. reset
7. Realtek driver s linka koji sam ti dao
8. reset
Ako tako ne radi, ne znam onda, vjerojatno je neispravna ili još ima neki
feature u BIOS-u za koji mi ne znamo.
BTW, našao sam nešto:
I can not successfully install drivers for onboard HD audio codec under Windows XP, can you please provide detailed instructions on installation of drivers?
Before installing HD audio codec driver please make sure Win XP has been updated with SP1 or SP2. If SP1 or SP2 has not yet been installed, please try install service pack through Windows Update.
Please make sure service pack and patches are properly installed. If SP1 or SP2 has already been installed, kindly make sure that the system is not overclocked and also that onboard HD audio codec works at default settings.
Follow by inserting the driver CD’s which is provided with the motherboard, when prompted with a pop-up box please select "Xpress Install" on the top right corner to install all the necessary drivers.
If you want to manually install the HD audio drivers then you will have to firstly download the Microsoft Bus driver and install it. After you restart the system please check the model of your onboard HD audio codec, and download the matching audio drivers for installation. After the mentioned procedures are done the onboard audio should work accordingly.
The following links are drivers for different audio codecs:
