In Windows XP, stop messages 
generally take one of five forms:          
1. Software errors during Windows 
operation. 
Software or device drivers installed in your computer may have errors or 
problems which cause a stop error, either constantly or under certain 
conditions.         
             
        
2. Hardware errors during Windows 
operation. If a 
hardware device malfunctions or is removed during the operation of Windows, or 
if your hardware does not fully support the operations that XP expects it to 
support, a hardware stop error will occur. Outdated BIOS information on older 
computers might also be an issue.  
   
3. Installation errors. The Windows XP 
installation process is the most sensitive time for hardware and disk errors. If 
there is a problem with your computer's hardware configuration or the media you 
are using to install XP, a stop error will likely occur.         
             
            
       
4. Startup errors. Corrupted system files, 
hardware and driver errors can all cause Windows XP to halt with a stop message 
without correctly booting into Windows. An error of this sort will almost always 
require troubleshooting before Windows can be loaded correctly. 
        
              
            
       
5. Intermittent errors. The most irritating type 
of stop message, these crop up consistently but apparently randomly. The most 
likely culprits for this include:    
           
        defective system 
memory,  
 an overheating processor,     dead or dieing hard 
drive    
 or faulty software and device 
drivers.   
What can you do about them?      
As you are probably aware, 
Windows XP can crash in all sorts of interesting ways. Even though it is 
massively more stable than its predecessors (Windows 2000, Windows 98SE, Windows 
95) people are still finding new and interesting ways to blow it out of the 
water.                        
           
            
Given the range of possible 
crashes and stop errors, it's difficult to come up with a precise set of 
instructions for every possibly BSOD. Websites do exist which contain lists of 
known stop errors and some potential solutions, and we would advise you to check 
them also in your quest for a cure. Try

The goal of this     PCSTATS.com Guide    
is not to provide specific instructions for fixing each possible Blue Screen Of 
Death issue.           
Rather we aim to provide a generic set of 
troubleshooting steps which will allow you to analyze and hopefully identify the 
cause of the error and correct it. If we do not cure your issues, by the end of 
this section you will certainly be armed with more information about what is 
causing them.
There are a few basic steps 
that you should always take in the case of a Blue Screen Of Death appearing. 
Let's look though them now...
