A memory upgrade is very easy. It's inexpensive to get some, and doesn't take that long. The catch is to look up mow much memory your computer is up gradable to (My computer currently holds 1 GB and expandable to 2 GB. It has two 512 MB chips). Adding more memory can make it run faster. Also, look up which kind of memory the computer can hold. Please visit
