Lost Internet Connection

[donsor]

Yesterday, I replaced the video card in my other computer. The new video card (ATI Radeon HD3870) works fine however I lost internet connection. It's not the service or the modem because my two other PCs' internet connections are fine. NOTE: I had problem installing the video card software using the installation disc (version 3.0) in the beginning. It hung up during the installation of Parental Control. I uninstalled and reinstalled the software twice but it still hung up. Fortunately I had a copy of the latest driver in my other PC and I was able to successfully load it and thus the ATI Rdeon card now works. Someplace along the line I may have accidentally deleted something because in the Device Manager, the following in the list of "Other Devices", yellow question marks appeared.

Other PCI Bridege Devices
Other PCI Bridge Devices
RT L8187 Wireless
SM Bus Controller

I have only two PCI cards installed: The ATI video card and the PCI EIDE hard drive adapter.

All other features of the PC work fine. Sounds like driver problem, what do you think and what do you suggest I do.

Thanks

Reinstall the motherboard drivers.
