I have an older Dell Latitude laptop in which I would like to upgrade the processor. I purchased the machine as a refurbished model. It has Win7 installed, The typical office programs 2007. I writing to ask if there is a way to upgrade the CPU without having to disturb the overall OS configuration? If not can someone either give me direction as to how one goes about doing this (w/o WIN7 disc) or a link to where I could get direction as to how to reinstall after the upgrade. Thank you.
