Considering your system specification you can't play latest game like crysis 2, GTA IV and many other

. Your lappy has Mobile Intel(R) 4 Series Express Chipset Family graphics which is an integerated one

. Better if you have a dedicated graphic card and a little bit nice CPU like a core 2 duo 2.53 Ghz. You can play games which was released before 2006 like GTA:San Andreas, vice city and many other but at low setting or at high settings.
