I modified a toshiba 2545XCDT laptop to make a touchscreen computer/mp3player for my car. The computer had 64mb of ram. It runs kind of slow and the ram port in it is broken so I cant upgrade. I have XP installed on it and all I want the thing to do is boot up and run two programs...iTunes and the driver software for the touchscreen. My question is can I shut down any windows functions or processes or anything to increase speed while still being able to run iTunes and the driver software in order to increase performance? If not, is there anything else I can do?
