|Do you have the latest active x installed. Check your security settings for scripting in web pages as well.|
Also...you report only 512 in ram...this small amount with IE8 may cause the web pages to be very slow in loading....try to do a thorough cleaning of the cached files and temp files as well as the prefetch files.....google for a free program called ATFcleaner. Run it for cleaning those files and allow plenty of time for the web pages to load and they should load a lot faster with a newer version within the prefetch folder.
