Browsers will not open certain websites

[Quakky]

Hi,

I have a small issue with a PC that refuses to open 2 websites (sorry I can't disclose them). Basically it's like opening youtube from home, and not being able to do that on this PC with the issue.

the weird part is that this site used to work on that pc, however now it does not . To try to diagnose the issue, I tried installing firefox on that PC, sadly it started working but not for long (as it was reported to me). Computers on the SAME network are able to get on this website, so I dont think it's a network issue. I also am 100% sure the site is not down because other people are on it at the same time (or around the same time) as when I am trying to log on to this website.

pinging the website in question returns packets so I really dont know what to do.

On that PC there are no firewalls (just the network firewall) and it is using AVG antivirus

PC specs:

Vista permium
2GB ram
Duo core (at 1.8Ghz)
500GB HDD
IE7 (not working)
FF3 (not working)

Thanks in advance for everyone's suggestions

See, if you can access those sites in Safe Mode with Networking

Well... I once had an issue with a modem that hadn't been reset for several years and it started to refuse to handle requests for certain pages... Resetting it turned out to fix that.

Please, start your own topic.

Sometimes clearing the browser's cache and getting rid of files in the Temporary Internet folders works for me when I can't get a site to open or it's incredibly slow. Just clear everything, reboot and see if that helps at all.
