I had the same problem with IE and Google Chrome Web Browsers. I posted the thread but I got no reply. Try unstalling Google Chrome first. If the computer works fine with just IE8 please tell me. If it doesn't work try downloading Ccleaner from click here This will clear out your system and correct your system from conflicks. Eg. 2 anti-virus programs or 2 web browsers. Do not try to unstall IE because it is extremely hard to reinstall if you use Google Chrome. I have more ideas. But first try this one!
