text: how do i find out how much actual memory i have and how much should i have to operate well.?   right click my computer and go to properties on the general tab it will list how much memory you have. generally with memory, the more the better. for win 98: 128-256 mb is good, over 256mb and you won't see performance upped much. for win 2000 or xp: depending on what you are running for software, 256mb or above.
