Hi all, please bare with me as I'm new on here and not techno minded at all. I purchased a computer for my son last christmas for gaming purposes, and it came with a 32 bit? This year of course most of the new games a 64 bit? Please can someone help me as to how I go about changing it. I have the windows 7 disc service pack 1 if this is relevant... I seriously need to get this sorted before Christmas...I have just purchased 2 x 2 gig of Ram to update the memory. Many thanks from a frustrated technophobe mother?
