Yah what he said too. Cenozoite End it all is a program to stop all your GUI's . Thoughs are programs like whats in your tray that run in the back ground and eat up resources . I am not sure about ramboster but there are ones that kind of take back used up ram and make it avalable again. One other note It not the same to use the restart option to reboot as all your ram does not become available unless you do whats called a cold start meaning you use the shut down option then wait a min or 2 then start back up. Normally this doesnt come in to play unless its a situation like yours and you need all the ram you can muster. Every little bit helps .
