Stuttering Problem In All Games & Online Videos

Hi,

My old laptop has been having a stuttering problem with games for a couple of years now. It’ll stutter for around five seconds, run smooth for around ten seconds, stutter again for five, run smooth for ten. It’ll keep doing that until I stop playing and close the game. It doesn’t start doing the stutter the second I start the game, it’ll start maybe around five minutes into the game and not quit its pattern. It doesn’t matter what game, how old it is, it does this to all.It also does this while watching online videos. I can’t watch anything on, for example, Hulu, or Gametrailers, without it doing the same stutter pattern.I didn’t always have this annoyance. It started little over a year after I bought my laptop. During all this time, while putting up with the problem, I’ve done several clean installs. I’ve tried to solve this myself, but never could find anyone with the same exact problem.

Please help.

I didn't find the right solution from the Internet.
