IE6 and firefox lose connection after about 5 minutes..HELP!

[fallion55]

I'm having problems with my browsers (IE6 and Firefox) connecting to the internet. Symptoms: I can connect and surf the web for about 5 minutes and then they stop working (the icon in top right keeps going but they don't find the sites). It's a really wierd bug. The icon in my taskbar is still active and enabled and when i repair the connection everything seems to work... but i can't browse.

Here's what i've done. I called my (Cable internet) isp and they said everything checked out on their end and that it has to be a hardware or software prob on my end. I scanned for and removed viruses and spyware untill Avast antivirus and Microsoft spyware removal tool both said i have 0. I had to remove several... some of them manually. I downloaded hijack this and ran it and it looks clean... to me at least. I checked my power management settings for my network card and disabled stand by mode. I downloaded and ran winsockxpfix.exe to make sure it wasn't a winsock problem. After all of that I still can't get my browsers to run longer than 5 minutes so i figured I'd post my hijack this log and maybe some guru (i'm definately not one) can offer up some suggestions. I offer my advance thanks and many prayers in return.

Heres my log:
