Intel 945 GM problem or software ???

[axiz_23]

Hi...i recently bought a Lenovo N100 3000 series laptop. This is the configuration :
Intel Pentium dual core 1.73Ghz...
Mobile intel 945GM express chipset integrad graphics
2 GB Ram
120 GB SATA hard drive
and on board realtek soundcard
Windows Vista Home Premium


I tried to install a few games and play but its not workin.......i tried NFS most wanted but its too slow (the frame rate...) even thought the graphics is kept at low settings but still there is a lot of framing ! please let me know if i can do nething to solve this issue...i dont know if its a hardware issue....i installed the latest drivers and updated the BIOS but no use...apart from this the system works fine....

Another quest i had is ... wanted to know if i can change the on board chipset and add an pci-express graphics card to it... cause i cannot find any slot...but is ther any method to do so ?

And the last problem i hav is whenever i use yahoo or google chat the CPU usage shoots up nd the conversation looses its clarity and soon the call gets disconnected ....i donno why this happens ...


Please Help... !!!!
