Let's start with the assumption that you are using Internet Exploder in one of its forms. (No harm in that - half the world does!)
How about downloading another browser - Firefox seems flavour of the month on here - access the internet in the usual way, and see if you get the same effect? Takes less than a quarter of an hour to set up, and costs nothing.
Either it will work or it won't. In either case, come back and tell us, then someone much more brainy than me will possibly have an answer.
Good luck.
