Dell XPS l702x slowed down when playing video online or play game ...

Question

Dear Dell community, My XPS L702x recently slows down when i play video online or play game. My configuration is: i7 2630QM, GT555M, 6 GB ... Before i never had this problem, i played video online and played game ( Skyrim, COD, A.V.A online ....) smoothly. But for 2, 3 months ago, my laptop slows down and spikes very much. When i watch video online, the screen will freeze 3 to 8 seconds but the sound is still playing. And all games that have run smoothly before, now they lagged too much, for example in Skyrim, when i start a conversation with a NPC, the game will freezes 2,3 seconds, and in the combat it freezes everytime when there's a sound is played (i.e screams, sound of sword slashing, footstep ...). I have Microsoft Security Ess, no Semantec, Kaspersky, Norton ... And i have re-installed the Win 7 ultimate, but nothing is fixed, i've updated all my drivers, BIOS, Graphic card, sound card, wifi ... Nothing helps. Please, some one help me, this problem is very annoying, i can't do anything with my laptop now, even opening Google Chrome is not easy. I'm really stressed. Ps: My battery is broken, i use my laptop on AC adapter only, perhaps this is the cause but i don't think so. Because i have a HP Pavillion and the battery is out too, but the HP is not slowing down.
