PC Running Slow, Hangs, Freezes:

- Many users are not aware of how much RAM is used by wallpaper and/or a screensaver full of graphics. They run in the background and consume memory. (I have only 512mb RAM, run multiple programs simultaneously, and have set my wallpaper and screensaver to blank.)

- How many programs do you load at startup? Maybe you should check it out and ensure you are running just what you need.

To do this: cl Start, cl Settings, cl Taskbar and Start Menu.

- cl Start Menu, cl Customize, cl Remove.

- cl the icon for the program you wish to remove

- then cl Remove.

- This will prevent the program from loading at startup, but will not remove the program from the hard disk.

- When you are working in a large file, save frequently to restore full memory access. (Your work remains in memory until you 鈥渟ave鈥?it to disk.)
