Thanks for your awesome instructions with Links :) - that really helps a noob like me!
Try resetting your Windows Hosts File to default
When I attempted to change the host file using the directions given in the link provided I found that there was NO host file there! The directions given led me to Computer-->Vista64-->Windows. The host file that I'd seen and edited in the past was in Vista64-->Windows-->System32-->drivers-->etc
So I added a host file to the correct location with the info given but that didn't resolve the problem.
Make sure to switch your LAN and Wireless settings back to DHCP including your DNS's.
They were already set to DHCP
Let's also do a Clean Boot
This didn't have any effect...I had everything unchecked and still had the problem
restart your computer, Tap F8 and select Safe Mode with Networking. In here see if you can browse.
AHA...finally!!!!!!!!!!! I'm able to open webpages in safe mode, even when I cant in normal mode.
So, I'm guessing that its a program issue? Does that mean its time for a format?
I dont understand why I can be going along, working fine, then suddenly no pages will open for me. Also, I can be chatting away in skype or google talk while the pages wont open...whatever is wrong, its only affecting my browsing.
But whatever is wrong, I am so happy that we're getting closer to resolving it!
