If you want to increase the speed/performance of your computer without having to buy an extra RAM then there is an amazing feature in Windows 7 called ReadyBoost. This feature allows you to change your Flash drive, or memory card into a RAM. That is if you have 1 Gb of free space on your Pen drive then plug in the pen drive to your computer. And then right click on the Removable drive and select properties. Then go to the ReadyBoost tab and check enable readyboost and set the memory space you want it to use. This will make the computer use the free space from your pen drive as a temporary memory. This will not provide a big speed change, but it will sure make some performance improvement.
