The easiest way to modify your screen resolution is to:

Look for a computer screen icon in the system tray (located at
the bottom right corner of the screen near the time display).
Left click it and select 1024x768. That's all there is to it.

If you don't have the icon:

1) Minimize the window(s) you have open
2) Right click your desktop (anywhere)
3) Left click "Properties" on the popup menu
4) Click on the "Settings" tab
5) Adjust the screen resolution to 1024x768
6) Click "OK"
7) Click "OK" again on another popup window
8) The screen will go dark for a second or two
9) Click "YES" when the screen comes back resized

You might have to resize your browser window - upper right
hand of the window; use the middle button between the "-" and the '+".
