Hi,
After reading your explanation I think the problem is windows XP hiding the MemInfo icon.
Do this steps:
Right Click the Taskbar and select Properties.
Click the Customize button in the notification area box.
make sure MemInfo is set to always show like in the screen below:
Press
OK to close both Dialog windows.
To access MemInfo settings simply right-click in the graph and select
Settings in the menu.
Let me know if it worked.
