After re-installation of WinXP no audio components are recognized. In the hardware manager there is a question mark next to the Audio, the Ethernet-Controller and the SM-Bus-Controller. There is no Realtek icon any more on the RHS bottom of the screen. I tried to install the Ethernet-Controller (internet download) and I've got the massage "please shutdown and plug realtek pci card". How can I mitigate the problem?
