Computer Freezes Up when watching videos or listening to music or playing some games.

I've beenexperiencing this problem for awhile now. When I watch videos (for example, abc.go),play pc games, or listen to music (itunes), my computer would randomly freeze up and make a loud sound. The audio would sound like abroken record and I can't exit out so I have to do a hard shut down on mycomputer. Also, I notice my internet connection is slower than usual. I do havevirus/spyware protection and I have scaned to see if there was a virus, but itshows nothing serious. My computer is about 2 years old. I would greatlyappreciate it if you guys have any suggestions as to what I should do. Thecomputer specs are:
