The first step is to go the 'standard CMOS' setup 
screen and note again the IDE devices that are attached to your computer. If you 
have the option, you can also go to 'auto-detect IDE settings' which will 
enumerate all hard drives and optical drives for you. 
 
Following this, there are a 
couple of other areas that may be of interest: 'CPU PnP setup' may contain 
details of the processor type and speed. 'Chipset setup' may contain details 
about the speed of your AGP (video) slot.             
           
            

    
  Exit without saving.
Getting information from the operating 
system 
In most Windows operating 
systems, there are two useful locations for collecting information about your 
system, the 'my computer' properties screen, and the Device Manager. To get to 
the 'my computer' properties screen, simply right-click the 'my computer' icon 
(on the desktop in 9x/ME/2000 and the start menu in XP) and hit 
'properties.                        
                           

 
In the above example, (Windows 
XP), you can see we have the amount of installed memory, and the type and speed 
of the CPU. WindowsXP is rather more helpful in this respect than most other versions 
of Windows, but all of them should give you at least a reliable account of the 
amount of memory you have installed.
