Is there a way I can speed up my computer once the computer starts up ,shutdown and even playing games? I have too many items on my startup tray, but I need those. I have a laptop that is Toshiba Intel Centrino Duo Core, 1.5 GB of RAM, Harddrive Capacity 150 GB, and 1.6 GHZ. But somehow the computer is still kinda of slow. Thanks!
