I see you use firefox web browser, i have never used it myself but was wandering if it has a pop up or active x filter maybe thats blocking you from opening up web pages fully, i use internet exsplorer 7 myself
in firefox , go to tools at the top under the title bar then choose clear privvate data , then select the options and click ok
n ie make the menu bar viewable by right clciking in the top section under the address bar and select menu then go to tools and select clear browsing history adn there are some options simmilar to in ff
also could this be a graphics card problem what is your graphics card cos i had a problm with displaying colour imagges and i updated my graphics and it worked
well for mozilla, go to tools-options then click on the content tab. under fonts and colors click the advanced button, and make sure the allow web-sites to set their own colors and font's checkbox is checked. For I.E. which version?
