I've never heard of a mouse cursor being affected by RAM usage, but that's just me. The mouse cursor isn't a huge bitmap, right!? If it is difficult to position the mouse cursor then it is likely due to extremely low framerate. (iirc CTRL-F8) And that is usually due to performance lacking graphicscard, or it's settings.
My optical mouse sometimes grows legs and start to run of, which is often caused by dirt or small hair in the optics hole. Or it cannot see a patern under it. Also, if you have a touchpad on a laptop but also an external mouse connected, do keep in mind that both usually work alongside. You may be touching the touchpad with your sleeve or something.
To better diagnose this problem I think we need to see some visual examples.
