The last few days,almost everytime I use the control panel for anything it locks up and quits responding. If/when I "End Task" my desktop icons,toolbar and cursor disapear and I have to reboot to get it everything back again. I ran a few diferent spyware programs,Hijack This,and Nod 32,nada. Defragged also. I'v got XP MCE and everythings been updated. Any ideas?
