W7 - NO REASON: Internet Explorer cannot display the webpage Error

[frochin]

Hi, this is my first post here and I feel force to post it after reading and trying everything that I found on the web.

Here is my specs:
Windows 7 RC Build 7100
1GB Ram
P4 m (Pretty old laptop)

Anyhow.. here is the deal....

One day out of nowhere as soon as I opened IE8 (Which comes with Windows 7) I received the Internet Explorer cannot display the webpage Error.

This happens every time I try to open any web page! (And I mean ANY)
what id does: it kind of looks like loading for a sec and then either:
1- Displays Internet Explorer cannot display the webpage OR
2- Keep loading forever and show a completely blank page

I tried reseting, uninstall and reinstall IE8 (can do in W7 as Feature), reboot like a zillion times, etc.
Even tried the No-pluggin IE8 that comes on tools.

I had no antivirus at the time this problem appeared. Now I do, I though maybe a virus or something.

What else I re-check:
Correct IP address
Correct DNS Servers

I was forced to install another browser (Wont say which one) and thats where Im posting right now. So yes.. I DO NOT HAVE A CONNECTION PROBLEM.

I run the connection diagnostics and says everything is fine... but still cant load any web page.

I cant think of anything else, does anyone has a clue on whats going on??

Thanks
