Hi Denise...


Add the extra memory modules first and go from there. However keep in mind that if you have a total of 4GB or more and you are running Vista 32 bit, your system will not recognize more than 3GB.


If you should upgrade the OS, it is not that simple. Sure you can pop a disc in and upgrade, but in my opinion, I would backup all things *holy* and perform a complete install, as in formatting the system drive. If an upgrade from the original OS is performed to Win7, then those errors or issues you had previously, tend to follow or migrate to the upgraded OS. Besides if your current rig is 32bit and you want to go to 64bit, then you have no choice but to format.


Oh, you will need to download the 64bit drivers as the 32bit versions will not work if you go 64bit.
