can ping but not browse

[callipepper]

This has been addressed all over the internet, but I have tried almost every solution offered, and still have had NO luck. I can ping but not browse!
I have DSL from AT&T (spent hours on the phone with them), and they have reinstalled every line and jack in our house. Filters are installed before the phones. It's a speedstream 5100 modem. Not wireless and no router, as this is the only pc here.
I have tried all the solutions they had to offer, such as turning on and off the modem, uninstalling connection and reinstalling connection. Lines were tested and are fine. I used the self-support tool. It says fine those first 10 minutes when I can browse, then says no connection when I can't. But I can still ping. They ran out of anything it could be on the phone company's end. The problem has to be here.
Ok, this may be long, but I want to cover everything, and I'm not very good at this. This is a stupid problem though, so I'm sure it can be fixed! Any help is so welcome.
Following any suggestions made on websites online, I have both automatically and manually set the DNS addresses. I have pinged both myself and my ISP successfully. I seem to be able to ping with a number or a yahoo.com type address. I can sign into yahoo and msn messenger. I even have internet connection in IE for about 10 minutes after I reboot. Then one page just wont load, and no more will either, until I reboot. I can ping all day long though. When I asked the unloaded page to diagnose, this is what I got...

So, I looked that up online. I figured I would have to fix this Winsock thing and ran a program on that. It didn't hurt, but didn't help. I disabled some extras in startup. That was someone's suggestion, and it went about the same, but windows loads faster now. I also tried this, Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset TCP/IP stack to installation defaults. netsh int ip reset reset.log

Reboot the system and see if IE will connect.
One worked, on didn't.
Also, before all this, I ran a virus check with AVG and checked for spyware... nothing seemed unusual. My cousin even hooked up another computer to my modem and lines, and that one worked fine. This one did too, until a few days ago, and nothing new was installed then. I have updated IE, so it's the newest version. I even reinstalled it first. Short of reinstalling windows, does anyone have any ideas?
