PC says I have no internet access

[iscopedthepope]

So I have my PC at home. Up to yesterday everything was fine with the connection. Today when I turned on my PC ( It's connected through ethernet ) it says my PC is connected to my router but there is no internet access. When I try a wireless connection it too says I have no internet access.

The reason I find it strange is because I have an xbox connected through ethernet to the same router and it has a perfect connection. My iPhone also has a perfect wireless signal from my router.

I have tried fixing it with the Winsock thing, didnt work. Tried disabling and re-enabling the LAN and Wireless network, didnt work.

If you need anything from my pc posted here I will be glad to do so. Currently using Win 7

go Start then Run in XP - (Windows key plus R in Vista and Windows 7), then type in the following, including all the spaces:- cmd /k ipconfig /all -- then press Enter and from the black form that shows up, take a note of the numeric code. Type exit to close the black form.
