I own a Dell M5010, with an AMD Phenom 2 P920 quad core cpu. The laptop becomes very sluggish as in when i am typing something , the key presses are so delayed that the laptop seems to type by itself. This occurs mostly after playing a video game for about 2-15 minutes and ,while in game, if i press 2-4 keys simultaneously, the laptop doesnt recognize new commands (keys pressed) and makes beeping sounds until the 2-4 keys pressed are executed.

Problem appears even without playing games and it fixes itself for some time after a new boot.

Also, the beeping sound is coming out from the speakers.

What could be the problem?
