hey i found your problem uhh your cpu and ram is good but you graphics card sucks balls no offense but it does look
Chassis with Intel® Graphics Media Accelerator HD with 128MB of dedicated system memory supporting Microsoft® and Mobile Intel® HM55 Express Chipset
im not a hardcore pc person that needs a 400 doller graphics card i have a ati radeon hd 4350 which suits me perfectly it gets the job done i can play fallout 3 on high at 1280x1024 thats pretty good, so if you can (some laptops you can) take it to a shop or do it your self but buy a better graphics card and installed it but i doubt that you can so yea another thing that might be what are you running the game at?
graphics level low,medium,high,ultra
hdr and bloom and vertical sync
and anti aliasing and astropic filtering
