|Turn on your firewall and antivirus program, they are essential if you are online and are not your problem.|
First, open your browser, go to tools, internet options, and delete files. You want to clean out ALL cookies, ALL internet files, and ALL history. You MAY leave passwords if you like, but I do not let my computer supply these, so I clean them out too.
Then look for how your pages are displayed, I think it is on the advanced tab (I'm not using XP now) and make sure that it will show graphics and not text only.
I hope that this helps you.
