I purchased a Lexmark All-in-One (printer, fax, scanner and copier). When I turned on the All-in One I could not move the mouse unless I unplugged the USB from the All-in -One. I was told by Lexmark I needed more memory. I have ME operating system. The speed is PC/100. I purchased 256MB SDRAM and installed it. I was told to update the BIOS also. I did everything and still my system is quite slow. It did resolve the problem of being able to use the All-in-One somewhat. What could the problem be?
