xp keeps freezing help?

whenever im watching a movie, on the internet or playing a game my computer freezes up. When it freezes the programs will suddenly stop and i cant alt-ctrl-delete my way out of it. i can move my mouse around but i cannot click anything. if there was a sound in progress usually during a freeze it will repeat over and over. Ultimately i have to reboot the system and after it comes on my computer will vary anywhere to within a hour before freezing again. Never had this issue before so i tried a dozen of anti viruses but nothing works.
