Q. I have a Dell Dimension 9100 with two sticks of 512 megabyte RAM. I'm trying to build a special slide show for my 12-year-old twins. I'm using Roxio Easy Media Creator and Photoshop elements. But my computer keeps locking up. Dell support told me to install two one gigabyte RAM sticks to max out the memory. Shouldn't I install four one-gigabyte sticks instead?
