RAM stands for Random Access Memory, and it's also known as your computer's Short Term memory. If you don't mind fiddling about with your computer's innards, it's a straightforward job, but, if you don't fancy doing that, ask a local computer expert to do it for you. Tell him to install more memory. He will find out exactly how much extra memory your computer can take, and he'll do the job for you. I got a local PC expert to do it for me, plus a repair job, and everything now is running fine.
