Is this the only computer that can't connect? Do you have another on this same router that it is working? Is the Internet light on the router lit? What make and model number is the router?
Copy the next 5 lines:
ipconfig /all > \junk.txt
tracert -d -h 3 8.8.8.8 >> \junk.txt
net start >> \junk.txt
notepad \junk.txt
echo done
Start, All Programs, Accessories, right click on Command Prompt and Run as Administrator, Yes. Right click and Paste or Edit then Paste and the copied lines should appear.
Wait about a minute for it to finish and for notepad to come up.
Since you don't have Internet you will either need to copy the C:\junk.txt file to another PC with a USB or just tell me what it says:
For ipconfig /all you will get something like:

Just tell me what is different in the boxes.
For the tracert you should get:
Tracing route to 8.8.8.8 over a maximum of 3 hops
1 2 ms 1 ms 2 ms 192.168.11.1
I expect the next two will just have * and time out.
2 296 ms 269 ms 275 ms 98.125.215.1
3 313 ms 305 ms 305 ms 208.110.248.153
Trace complete.
