hi,,, vista is a very greedy os as regards RAM,,,, the accepted sweet spot is 2gb for vista,,,, google the motherboard and see if you can upgrade to 2gb.
you can also close down services that you dont use ,,, look on this site to see what you can close with out any problems,,,http://www.blackviper.com/WinVista/servicecfg.htm
this link takes you to vista service pack 1 configurations,,,,, keep a note of the one's you change, just incase you have to change one back.
also close down most of your start up programs, as there not needed,,, all i have on start up is my security,,,
type in the start menu search box,,,, msconfig,,,,, then click on msconfig.exe,,,, then click on start and uncheck the programs you dont need starting up when you switch the pc on.
but as i say the biggest improvement will come by a ram upgrade,,,,,,,,,, good luck.
