Intro: I was doing some computer work for an elderly couple when the internet on that computer randomly stopped working. Rather than having me fix it, they simply bought a new computer. Once I got the new one up and running, they gave me the old one. I'm trying to get it set up so my step mother can have her own computer (it's actually not too bad a computer). The only problem left is the internet problem. Problem itself: the problem persists on ethernet and wireless connections. The computer shows itself as being connected without any problems but chrome/firefox/ie all show "page not available" messages. They don't say dns problems specifically, but I'm pretty sure that is what I'm looking at. I can ping various ip addresses and google.com without any losses.. I did a tracert and nslookup for 188.8.131.52 without a problem. I've tried configuring the computer to opendns and 184.108.40.206/220.127.116.11. Neither worked. Disabling windows firewalls and the installed antivirus did nothing for me. There are no proxies set up on the computer. Antivirus/malware scans come back clean. At this point I really don't know what to do with it. Had the people kept the install disks or backup drive on the computer, I'd have just restored the computer to factory settings. Any ideas would be greatly appreciated.
