help needed with re-install of windows that has gone wrong?

owing to Adware problems that i couldn’t sort out i recently re-installed my windows xp, i am fairly new to computers and i have run into problems. The re-install seemed to go ok and everything has started but when i try and run my blueyonder disc to install internet it says it doesn’t detect my modem. All leads to the modem etc are connected and i can’t understand what the problem is. Is it possible i’ve deleted something i need while trying to delete the adware or could i be missing a disc for the re-install? I have windows xp 2003 edition and the operator manual says dell demension 4600 series. I used the operating system disc for the re-install and then ran the microsoft works disc. Also i seem to be missing some things in device manager, there are question marks by ?Ethernet Controller, ?Multimedia Audio Controller, ?PCI Simple Communictions Controller, ?Sm Bus Controller And ?Video Controller(VGA Compatible). Any suggestions on this matter will be greatly appreciated

You may be missing some of the drivers for your modem. If you bought the modem aftermarket go to the company’s website to download a new driver (of course you will need to use a different computer) if you bought it from Dell or someone else then go to Dell’s website and they should have all the drivers you need. Typically it’s under support, I think all major computer makers have a support link.
