Problem z web dostopom

Pozdravljeni!

Pred dnevi sem kupil nov pc in zdaj postavljam Win7 ter vse ostalo šaro..
Pa sem opazil, da ne morem dostopati do nekaterih strani, trenutno npr cnet.com.
Stran sem vcasih veliko uporabljal, saj downloadam od tam razne programe, zdaj pa kar naenkrat ne morem dostopati do strani. Izklopil sem tudi firewall, ce bi to lahko bil razlog, samo enak rezultat, takoj dobim error:

The connection to the server was reset while the page was loading.
The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer's network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

Preko proxyja pa normalno dostopam do strani. V cem je problem? Kakšna ideja?

TIA,
Matic
