Windows XP had been one of my favorite operating system and still I am using it in my computer. I am frequently updating all the update things as well as security things. Yesterday I have seen a strange problem in my computer and that my CPU usage jumps up to 100% while I open Youtube video on Internet Explorer and the screen lock up. Furthermore when I am try to play mafia wars, then also the same issue. I cannot see any videos. What wrong with this computer?
