Have you ever had a problem with your computer in which the game you play does not run smoothly? This problem usually happens when the hardware in your computer does not support. For example, you are going to play a 3-D game and you come across this kind of problem. The problem can be caused by several factors: first, the processor in your computer is not fast enough. This problem can be solved by upgrading your processor with the new one having faster and better performance. Second, the memory, or usually called RAM (Random Access Memory), of your computer is not adequate. Try to increase the capacity of your RAM. If your computer currently uses 256 Mega Bytes or 512 Mega Bytes of RAM, try to upgrade it with 1 GB or 1.5 GB of RAM. Third, the VGA card can also become the cause of the problem. VGA card functions to display output on the screen of the monitor. The 3-D games usually require a good and fast VGA card. So, you can upgrade your VGA card to get a better performance.
