Win XP (home) SP2

Using these video cards have been known to be difficult as their direct x runs into trouble with windows xp directx.,Only way to install them is on a clean hdd with no previous regestry entries.. suggest you shutdown your machine unplug the power, remove the card and plug your monitor back to the mainboard onboard video card.
Reboot to "safemode" without it to flush cache, then check and uninstall its associations While in safemode. drivers etc. once done reboot again to flush cache. Now using the cd that came with this card install it.
Shutdown unplug power and put card back in move monitor back and reboot. See if that fixes it.
With windowsxp sp2 there is lots of known issues with networking and there is plenty of available help if you use the google search type in networking xp sp2 and you may be surprised how much is available. Good Luck

You either don`t have a DHCP server set up so it spends time searching for one. I find it best to specify a static IP address and cuts out this searching for a DHCP server.
I using a ADSL modem then having it left on all the time will reduce the search period.

I have an ATI 9000 and it also adds 2 entries under device manager. I think this is 'normal' behaviour. Ignore it.

Try checking system setup and disable onboard video. If you are just in the process of setting up your system I have allways found it better, once ive encountered problems and tried to rectify them and failing, is to reload the operating system. If you do this unplug every thing, including the printer, except the keyboard, mouse, video. Make sure you have the latest mother board drivers. get the basic system running and then start to build one step at a time. On the network issue try as responce from PJ suggested but I would find out your dns addy but also your default gateway addy and manualy enter your ip addy select use static ip.
try that
good luck

The radeon series, especially the higher 9xxx series installs two interfaces by default. This is because of the fact that these cards allow for dual monitor support via a DVI adapter. Concider it normal and harmless :)

The only problem that you would have in the device manager is when a device comes up with a yellow ! mark or a red cross - that means that there is some sort of confliction there.

In regards to your slow network I would first look into the Internet firewall and make sure that home networking is enabled in the exception list.

My experience with SP2 so far in both home and professional configurations have made me conclude that there can be any given number of random problems that can occur. I had two EXACT systems which I rolled out with XPSP2; one installed fine without a hitch; one completely disregarded the domain server and network settings and took a few good hours of configuration....

Its a bit touch and go with SP2 - I would advise against it until M$ re-release it in 2005
