Slow Computer?

It's bound to happen. Your computer gradually becomes slower and less efficient over time. That's because your system memory requirements may have increased already. You download more programs with bigger files which need more, more and more memory. Not to mention that files like photos also become better (more defined with more pixels) but so much larger.

Short of getting a new computer, you can actually improve performance by upgrading your memory. It's probably the easiest way to improve your computer's performance.
