why not just go into settings and disable standby, I have never had any screensaver and no power down of anything, I can leave the machine all day and it won`t shut down, just right click the desktop, select the screen saver tab, disable the screen saver, then go into power settings (button in section marked monitor power with energy star logo) and set everything to "never", now the machine will never shut down or send drives to sleep or blank the screen, blanking the screen is a pointless exercise (unless you want to be eco-friendly and save energy) since modern monitors don`t "burn" like the old ones did...mine have never had any visible damage from running without screensavers (in 15 years) and in the case of TFT (LCD) displays, they won`t be affected at all since they don`t work in a way that would cause that effect, cheers.
