I have an Acer Aspire One AOA150 with Intel Atom processor N270 (1.60 GHz, 533 MHz FSB, 512 KB L2 cache) and 1.5G RAM and Windows 7 Professional is my current OS. According to acer technical support, I can't upgrade my RAM higher than what it is now. So, is there anyway to add up more speed to my Windows 7 Professional using different methods? Like what could I safely disable in Win 7 Pro; like unnecessary background applications? Is it possible to make use of a USB flash drive to add up RAM?
