Ok just upgraded PC to XP - its quite an old machine 128megs ram - PIII

I only have IE, AVG, Outpost running and my CPU usage is at 100% oO

Computer is above minimum spec for XP but I dont see how if this is what it is like normally - anyone got any ideas? I dont wanna see what it runs like when i start running Flash MX or Photoshop >_<;
