hi jeswin
sorry mate,thats not possible .... the only technology that allows that is AMD,s apu based systems,and then theres very few laptops that support it
however people with intel based laptops cant combine the on-cpu intergrated graphics with the GeForce 210 graphics as theres no technology in place to do this,allthough some laptops have specific buttons which allow the end user to switch from the low powered intel HD graphics to the dedicated GeForce graphics ...this allows the user to save on battery power and only switch to GeForce dedicated graphics when gaming
this is the problem with laptops ... many guys buy them expecting to run most games,however unless they have a high powered GTX760M or better gpu then your out of luck,and most laptops with these powerful gpu,s tend to be very expensive ( such as alienware and rock ) and these can cost over £2000 !
that said there are a few things that can let you get the best out of your existing graphics,especially the GeForce 210 and these are
1) update the drivers ... go to http://www.nvidia.co.uk/Download/index.aspx?lang=en-uk and using the drop down menu,s loctate the driver for your GeForce 210
2) download and update the direct X runtime files ... go to http://www.microsoft.com/en-gb/download/details.aspx?id=35 and download the latest direct x ( you must be connected to the web to run this )
3) when running games set all video options to low and resolution to 1024x768... then slowly increase each video setting ( eg shadow,texture ) a bit at a time ... and monitor the ingame performance using a program called"fraps"( http://www.fraps.com/ ) which will show your frames per second (fps) in the corner of the screen .... don't settle for anything below 20fps as this will result in lag/stutter that makes games unplayable !
4) replacing your existing hard drive with a ssd(solid state drive ) will significantly improve the speed of your laptop.... you can buy a 60gb ssd for around £55 and this would be enough to install windows on it and then 2 of your favourite games .... running games from a ssd will result in much better loading times and in some cases better performance
5) upgrading your system memory(ram) can also improve the speed of windows and your games ... if your currently using 4gb of ram then going to 8gb will show a decent improvement ..
I hope this helps jeswin ... any questions let me know
good luck mate and happy xmas !
