My notebook is asus, 2GB memory, AMD mononuclear M120 CPU, but I installed 64-bit system, use up speed is a bit slow, plus a lot of asus drive, the velocity will more slowly, now I can't change 32-bit, because I 64-bit software has been installed a lot, using 32-bit system of words, many software must reinstall! Is there any way to slow memory use? The third party software or something to help? If you have, help give a download address, thank !
