hey guys i have problems with my k40ab i downloaded amd fusion for it and it messed up my system. my k40ab became slower and laggy even after unistalling amd fusion. also it doesn't display like ac power disconnected, lcd on or off, volume up or down when i use the function keys. anyone know the solution to this?

i'm using vista and i turn on the amd boost function the last time i used it. what do i do now?

haven't been here for months and this thread is still growing!
