I have a g6 with an i5.
Ram is 4 gb and a radeon graphics card. The point is that when ever I am watching a movie on vlc media player or playing games like Most Wanted or Arkham Assylum, the cpu usage goes to 100 after an hour or so and then everything stops, i open up the task mgr and after 5 min or so, things go back to normal, but it annoys. it never happened before, its just 2 days since it has begun to happen. Help anyone????
