hello, I have no idea whats happened, My internet connects to the internet but explorer will not load pages and tells me that it cannont find the DNS server. I've tried fixing it by other online posts, But was unsuccessful! I've tried everything but it does not even come up to see the properties. Please can someone help me on this? Thanks

Shut down the computer. Turn off all of the network devices. Wait a couple of minutes. Then turn on one at a time, starting with the cable or dsl modem. Wait to get all lights. Then the router if any. Then re-start the computer. Any luck?
