text: i have a gateway computer. it keeps losing memory. when i turn it on it's already at 24%.? i've tried deleting the temp. files and fixing my startup menu but nothing seems to help. i can only run one program at a time. gateway isn't any help. does someone know what's going on? if you have more than one user on the computer, than that is the problem. at boot, windows automatically divides memory between users to prevent problems later on for example  if u have 1gb of memory and four users, at boot it will give each user 250 mb of memory as if ur memory were being split between four different computers.  i'm not sure if there is a solutuion to this other than deleting users.  i'm not sure if this will work, but try disabling the fast user switching capability service.
