Problem with games stuttering every few minutes

[account_disabled]

Hey guys, I recently started having an issue with my PC and cant quite figure out whats going on. First of all, I am running an AMD64 4000+ with a geforce 8800gt and 2 gigs of ram. I know this isnt exactly up to date, but I'm not trying to run crysis and the games I am playing have worked perfectly fine over the years. So to the problem. Whenever I load up a game it runs fine as always, but every few minutes (like 2-3), my game will start to stutter for a solid 3-7 seconds. While this is going on mouse control is very difficult as all of my controls are affected by it. Whenever I restart my computer, I can typically play a session stutter free, but if I come back later in the day the problem will persist. I don't think my system is overheating (though I could be wrong), as I have never had an overheating issue in the 5 or so years I have owned this PC, and all of my fans are still functioning as they should.



Any help you guys can give is greatly appreciated as this is driving me freaking crazy.


Please help....



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