IE 6 wont' start up

IE 6 won't start up properly, it takes many tries, yet each try is listed in
running program list in task manager programs. Running Windows XP Pro. Dialog
box comes up ststing each IE6 try, is not responding, so must manually end
each IE6 program when shutting down. May have been caused by multiple windows
of IE6 running, when had to reboot hard with reset power button after getting
caught in web sites that wont close out.
