I've had a search, but couldn't find an answer here so...
I can access most home pages, ebay, google, yahoo, facebook, my bank etc, to name but a few, but whenever Press a link to log in, the page hangs and comes back with either a "Timed out" error (firefox 3) or "Cannot display page" (IE7). I also get the same errors if I try to register at said sites. I had this problem a couple of weeks ago but it was fixed by a re-format, however now it's back. I have done another format and so have a fresh install. The obvious I have tried; Power off the router, update drivers, cleared all browsing history (firefox and IE), full antivirus & spyware scan (although machine has been formatted). Turned off firewall and A/V. Device Manager is showing no errors.
My system / setup:- Packard Bell istart 2380 / Windows Vista Home Premium 32 bit Realtek 802.11g/b usb wireless dongle Netgear DG834 Router Avast Anti virus / Spybot S&D / Windows Firewall.
I'd be very greatful for any and all suggestions. Many thanks.
