Browser problems in Vista

I Hope someone can help with a frustrating problem I have with Vista Premium 32bit.
I recently bought a new pc and was forced to accept Vista. I have a major problem in that no matter which internet browser I use it stops working after about 20 mins or so. My internet connection is still working as I can still download emails and use msn etc. The problem is that none of the browsers I have tried will load pages and the browser freezes. When I go into Task manager I cannot stop the exec file relating to the Browser. I have tried all the main browsers with the same issue. The only way to resolve the issue is to reboot my pc. This means I have around 20 mins of browsing then I have to reboot. I never had this problem with xp. Is this a know bug in Vista? Does anyone have any suggestions?

Have you checked for any viruses/malware/trojans harbouring itself on your computer.

Yes. Not found any problems in this respect. To be honest, I seem to have have had this problem from day one of using Vista. I have Vista with SP1.

what browswer have you tried.

I am currently using a browser that has been open since around 11am and with 26 tabs open, and its vista.

We need far far more details

What browser
What antivirus
What firewall
how your connecting to the internet

I have tried IE7, Opera, Firefox, Safari and Chrome. I use Avast Anti Virus and Zone Alarm Fire Wall. I am with Sky Broadband. I do not use a wireless connection.

Have you done your 'updates' ?

There seems to be issues with Firefox 3, Zonealarm, Vista combination that cause the same problems you're having. A visit to Mozilla(firefox) forums, or Zonelab forums could be worth a try, but uninstalling Zonealarm generally seems to do the trick. You can always enable the Vista firewall while testing, and if successful, maybe try a different firewall.

Just leave Windows Firewalll enabled after uninstalling ZoneAlarm. Theres not much point in going overboard as your already have a hardware firewall built-into the Sky router.

This seems to be a problem with internet explorer im having similar issues with it in vista x64. it may be due to the flash plugin but no one seems to know for sure

It's always the 'security' software.
