Internet Explorer Problem

Hi, I have a problem since I got my new PC. First I had IE6 and I regularly found “Page Not Found” pages displaying randomly, because once I refreshed again one or two times the web page displayed normally. Well, I changed to IE7 hoping that it would dissappear that problem… but it didn’t and now I don’t know what to do because it is very annoying!

I guess it is something on my configuration but I can’t figure it out… maybe there is a configuration file that I can replace with one that does work? Any ideas are welcomed ! :smiley:
