Windows XP: Rechner hakt und ruckelt bei Videos. Tonaussetzter

Hallo Zusammen !
Mein Notebookk hakt/ruckelt beim Abspielen von Musik oder Videos. Hab schon Antivir, Spybot, Ccleaner und und und drüber laufen lassen. Festplatte ist auch defragmentiert. Ram Speicherbänke sind auch geprüft.
Werde langsam wahnsinnig mit diesem Problem.
