Playing games or other design software has nothing to do with D, E, F, etc. Your problem may not have much to do with C, but with your memory. I haven't heard that you can't play LOL because the hard disk is too small. I am Lenovo G470, so I still play. Look at your memory size. My notebook has a memory module. Now 2G, before running LOL and CF, will also be stuck. It's all right now.
