I think it is because your computer is trying to populate the "My Computer" window and in the process it checks for computers in your network whether you have drives mapped or not and your own network status. To make things quicker you can add your own IP addresses for your pc's: use 168.192.0.1 and 168.192.0.2 etc XP uses self config if you don't use your own IP's so if youtype 'IPCONFIG /ALL' from the command prompt you will see addresses like 169.254.x.x, that means it's self configuring. Alternatively, setup ICS(Internet connection sharing), one machine becomes the 'server' and the other a 'client'. The machine with ICS installed is the 'server' and will hand out IP addresses, you will have to configure this machine with an IP address: 192.168.0.1 ans set the other machine to DHCP.

You are correct sir. Look for the Belkin USB 2.0 PCI hubs, they support full power to all ports. This problem you are having could be due(like previous posts said) that when your DSL modem draws power it doesn't get it and therefore bombs out. Have a look though, if you have a 250W psu with an AMD processor it's likely that because you are already overloading the PSU your having these problems, by adding a PCI card with 4 USB busses that draw more power you are not realy solving your problem, you are worstening it. It might be worth upgrading your PSU rather than buying a new USB card if you don't need it... Just a thought.
