i plan on upgrading the memory in my computer from 128mb to 512mb. my only question is, will changing out the ram affect or delete any of my files. i have a lot of photos and music on my computer. i am using winXp home. i plan on backing up some of the stuff but i don't want to do it all if i don't have to. there's too much. i'm thinking that since it's just the ram and not the hard drive or anything that it won't affect any files. what do you think?
