I have a AMD 333 K2 prossesor with 64 mg of mem. My computer at times will not keep up with the time, at times when I drag the mouse the cursor will not move right away and when it does it will be choppy. When typing in a Word doc the letters will come out slower then I am typing. ( I am not that fast). When I reboot the problem will clear up but always seems to come back. I defrag but that only helps for a couple of days.
