hi,,, running vista with all the bells and trumpets needs about 2gb of ram,,, also you have 77 processes running with to little ram,,, this will cause slow downs and apps to take longer to load,,,, think about installing more ram aand stopping some of the stuff running on the pc to free up ram and cpu,,,, if you have a large flash drive,,, say 2gb then plug it into a usb and use the ready boost,,, this will help and show you what a bit more ram will do if installed,,
1/ type in to vista start menu search box,,,, msconfig,,,, then select it, when the window opens, click on start up and look at all the programs that are set to start on boot of the pc,,, you will not need most of these,,, i have 5,,, mostly security,,, always keep your security on startup,,, the others ,, if you dont need it to start on boot then uncheck them,,,
2/ shut down some of the services you dont need,,,, this is where you need advice on what to disable,,, here is a link to a site that will guide you through this,,,http://www.blackviper.com/WinVista/servicecfg.htm
have a read and decide if you want to do this one,,, dont forget if you make a balls of it you can go back and change it back or just do a post restore back to how your pc was using system restore,,,
when using this,,,, site you need to open services to make these changes,,,, type in to the start menu search box,,,, services.msc,,, and press enter.
this will free up some needed resorces,,, you could also turn off things like vista aero,,, but you will lose all the good looking stuff on vista,,, so a ram up grade would be better.
