I'd like to get some more RAM for my computer. Right now I'm using 1024 MB DDR RAM and I find when I'm running a Norton virus scan, my pc slows right down to an almost unusable state. I know Norton can be a real memory hog but it seem a bit strange that it becomes that slow. Anyway, I'd like to get some more but I don't know how much my motherboard can handle. Is there a way to see what the maximum amount of RAM my motherboard can handle before buying it? Is there a way it should be installed to run better. Is it better to have 2 512 sticks or one 1 gig stick Also, My wife and I run our pc under two different XP user accounts. Does that mean it's running everything twice, once for each of us? Wouldn't that slow things down allot? Is it better to have just one desktop between the two of us? Thanks for you help.
