Question : I just used System Restore to restore the Windows XP OS on my Dell D830 laptop to an earlier point in time; now the network card drivers are disabled & can't be reloaded

I just used System Restore to restore the Windows XP OS on my Dell D830 laptop to an earlier point in time; now the network card drivers are disabled & can't be reloaded.

Whenever I try to reload the network card drivers or wireless network card drivers, the driver either finishes loading, or I get an error message saying that the hardware can't be started.

I have used the Dell hardware diagnostics to test the hardware and all of the hardware tests OK.

In fact, the laptop was working just fine until yesterday, when it contracted several viruses and Trojan horses and then I had to use the System Restore feature to restore the laptop to a previous point in time.

What do I need to do in order to be able to reload the network card and the wireless network card drivers so that I will be able to regain my wired network connection and the wireless network connection?

Get Dr.Web Cureit and scan your machine first.  Then go-to below page and get BIOS update and then Network drivers, install it.
