Suddenly slow computer. Please help


Oct 11, 2012
So i noticed that my laptop suddenly became very slow BUT! Its only slow when I play online games, it'll be ok for the 1st 5 minutes but after that it'll really slow down, its weird since i can watch videos on youtube etc and surf the web without a problem. But if i try and play the game it will be sluggish.
My specs are: Intel(R) Core (TM) i3 CPU m350 @ 2.27GHz 2.26 GHz
Ram: 4 GB with 3.80 GB usable
and the system type is 64- bit operating system.
I have Windows 7
And no it's not a connection problem.
Also my cpu usage when playing the game doesn't go over 54% (mostly bounces between 23%-40%). and my ram is pretty stable at 53%
