First try to uninstall and again install new Yahoo Messenger. If it still doesnt work, you have to reformat your system. It happened because your system is infected by virus which severely triggered some features of your Yahoo Messenger or maybe your Drivers.
After reformatting your system your YM will surely work.
I am expecting your comment.
