I have been having some issues playing World of Warcraft. Mainly, it freezes and sometimes gets really laggy and I was curious as to what my results indictate.

System specs:

AMD 3200+
512MB PC3200
160 gb 7200rpm drive
radeon 9550 256mb vid card

I defragged a few days ago, scanned for virii and spyware and my score did not change. Also, I updated my BIOS and video drivers.

Thanks for any ideas as to what the problem might be
