I'm having a problem when I try to play DVD or Divx or any kind of Games, it just freezes everything and running slow. When I start some DVD I go in Windows Task Manager and CPU usage is about 100%, when is in idle state (when doing nothing) is 0%. My Computer has nvidia 7050 integrathed MoBo with 1Gb DDR2, AMD Sempron was not in Box package, in this Store they sold to Me a "tray Processor" (like for OEM, with 1 year warranty, not 3 like those in Box). Ram Memory is ok, I tested with memtest. Generally system runs stable for Internet use, Music and Office, that's what I need most... but when it comes to Movies or Games it just slows down.
Could it be a Processor or what? What first I must to look. Did someone have a similar problem?
