Reboot and enter the BIOS by pressing the appropriate key as pc boots.
Look for the Network card and sound card and disable them - save changes and continue the boot up.
In Windows go to control panel - hardware - device manager and remove the soundcard and network card - if listed.
Reboot - re enter BIOS and enable the network card - save changes - continue to boot. When Windows starts it should find new hardware and install the drivers.
Drivers may be found on your hard drive -
"From version 2.x of the recovery system onwards you can install applications from the c:\applications folder. Drivers can be installed from the c:\applications\drivers folder and utilities from the c:\applications\tools folder. You will still need to install Microsoft Works from the supplied CD." Quote from Motherboard support site.
Once network card is working reboot - enable sound card in BIOS OR install the soundblaster card.
