Windows 7 Local area connection doesn't have a valid ip configuration

[Ben Hutchinson]

I recently posted this on yahoo answers, but its been over a day and no replies so i came here to ask for help:

The edits are from yahoo, it's just a little extra info

I've had this problem for a few days now, for the last few months i have been using my school laptop to share internet to my main pc, the main pc has a very crappy wireless card and the reception is horrible. I had a virus a few days ago which i believe i have successfully removed, but after the virus was deleted my lan connection through the cable was disrupted and any attempts at fixing it using normal windows just gave me the 'LAN connection doesn't have a valid ip configuration' error. I've tried a fair few of the fixes online to no avail, when i tried using the ipconfig /renew fix i got another error 'An error occurred while renewing interface Local Area Connection : unable to contact your DHCP server. Request has timed out'.

I have both computers ipconfig /all data prepared, although i will only be posting the ethernet seciton due to character limits
