DNS server is not responding.

I have tried many fixes found here and around the web and I am coming up short. Could anyone help me out?

Issues:
After about an 5min-1hour, my internet browser stops being able to load webpages. Restarting the computer allows me to browse for a few minutes.
I am able to torrent/play online games with no issue beyond the 1 hour limit.
My computer is the only one having issues, 3 other computers on the home network and multiple gaming systems are unaffected by the problem.

System Specs:
Running a Windows 7 system.
Wired Cable Zoom Modem/Router.
Service is through Comcast.

Attempts to fix:
Ran Malwarebytes and Alvira multiple times - all threats removed
Reset the modem/router - no change
netsh winsock reset - no change
ipconfig/flushdns - no change
Entered the router and went into DHCP license renewal to 9999 min - no change
Went into TCP/IPv4 protocol and manually set DNS to 208.67.222.222 and secondary to 208.67.220.220 - no change

More about server responding
  1. disable IPv6 and see if it has any impact
  2. Go to Control Panel\Network and Internet\Network Connections

    Right click on Local Area Connection and select properties.

    Double click "Internet Protocol Version 4 (TCP/IPv4)"

    Enter the following information, this will give you a static internal IP for your network and use Google DNS servers.


  3. The DNS servers as listed in original message are from Comcast, and they seem to filter DNS requests to Google.

    @fatejobobeast, when this happens - open "Command Prompt", and try to ping these servers:
    ping www.yahoo.com
    ping www.comcast.com
    as well as
    traceroute -n 75.75.75.75

    Post results here
  4. Try these DNS servers: 68.87.74.162 / 68.87.68.162

    If that doesn't work, try calling Comcast and speak to a senior level tech, ask them if you can be put on the WHITE list
  5. this is not enough for resolved this problem.so this post was not good for me.
  6. i have done this but my issue not fix.so this post was not good for me..
  7. Thanks for the responses.

    After trying these suggestions and none of them working, I switched from Firefox to Chrome.

    It appears the issue was totally found within the Firefox browser, and I have had no issues since using chrome as far as loading webpages and flash videos.

    Again, thanks for the help, and I suggest to anyone else to try a browser other than Firefox or Explorer and see if the problem remains.
