one of the easiest ways for you to make sure that our computer performs well is to keep it clean. i always tell people that you should maintain a clean desktop (mac or pc). on a pc, keep your taskbar clean. if you don’t use a program remove it. if you download a program delete the installation file once it is installed. clean your computer on a monthly basis. on a pc, go to system tools from the all programs menu and do a disk clean up and defragment. on a mac, purchase a program called disk warrior. Go through your computer and get our files organized and delete ones that you don’t need. and BACK UP. it is so important to do this because computers fail.
