I don't know what is happening to my Xp. I started to slow down. First I thought it was blaster but i used Windows update before and updated NAV so it is not Blaster. ( i also used the blaster removal tool) - but i found nothing. I am using in the system background : Pulse, Nav, Creative Nomad Detector & Gamesurround Fortissimo III (soundcard) I dont know why but after a period of time it just freezes... What can it be ? please help me !!!
