Been having this problem for a bit now.
To narrow it down: Some websites do not connect...
If i was so to go
http://www.gamearena.com.au i would sometimes get the text on the screen, and it will say down the bottom of the screen, Connecting to 1.games.bigpond-images.com, but i would have some info on the screen... see image
and on youtube, the thumbnails for the movies do not work, yet i can view movies fine...
but the weird thing is... if i were to use a web proxy say hidemyass.com, i can view the websites fine...
another weird thing, if i leave it for a min, and keep firefox closed... i can access youtube.com and gamearena.com.au perfectly fine on IE...
i have disabled my firewall, ive reinstalled firefox... yes i still get this crap...
anyone ever heard this before??? im not sure about spyware, but i have no viruses on my computer...
