Yep yep no screensavers.....win95/98/xp......goto...start.... run....type in ...msconfig....hit enter.....got-to startup tab and uncheck all unecessary start up items so as much ram as possible is free and won't cause any intruptions......"nothing" in here need be checked for your system to run.....you can always go back in after your render and re-enable items you do want in start up.
