IP Conflict Windows System Error / Internet Connection problem (pic inside)

[V]

would also help to tell us which router you're using, do you have DHCP on?

Most likely you have 2 computers configured to get the same IP from your router.

Do this on each computer connected to your router:

1. Right click my network places and go to properties, or go to start - connect to - show all connections
2. right click on "local area connection" and go to properties
3. Click on Internet Protocol (TCP/IP) and click properties
4. If "obtain ip address automatically" is checked, check what the IP address is on each computer, and make sure the last digit of the IP address is different on every comp. If it isn't, it's probably safe to change the last digit of the IP address by 1 increment (IP address should be different, but DNS settings should be the same on each)

if that doesn't help then i have no idea
