آیا وقت آن رسیده است که کامپیوتر نو بخرید؟

      
        
          When should you upgrade your computer? Here are some 
        
        
          
            rules of thumb
          
        
        
           to keep


in mind.
        
      
    

      
        
          •Dead Components - Finally your 
        
        hard drive
        
          , optical drive, 
        
        power supply
        
          , or


        
        motherboard
        
          will fail.

These events can be from unimportant annoyances to seriousdamages, but it 

dependson the age of the computer, any of them could be the reason forupgrading 

to a new machine.For example old 
        
        power supplies
        
          are too often may cause problems 

and upgrading them can be dangerous. 
        
      
    

      
        
          •New Software - if you are upgrading an important piece of software that you 

frequently use. 

If you find it runs very slowly on your old 
        
        
          PC, it may be time for a new one


(or at least some more RAM). 

Valuing Your Time - Even with RAM upgrades and other internal change there's 

only so far you can upgrade any PC before 
        
        
          
            maxing out
          
        
        
           its 
        
        
          
            capabilities
          
        
        
          .


And 
        
        
          
            
              
                
                  
                    over time
                  
                
                
                   
                
              
            
          
        
        
          it will run slower and slower,especially as software gets larger and 

larger.

If you find yourself launching
        
        
           applications, then 
        
        
          
            
              
                
                  
                    wandering off
                  
                
                
                   
                
              
            
          
        
        
          to do something


else while they finish loading, it's probably time for a new computer.

            Compatibility
          
        
        
           – New features like Fire wire and USB aren't 
        
        
          
            at hand
          
        
        
           on old 

PCs. Not a problem if your

parallel port printer is still working, but what happens when it makes a bad 

noise? You might need a new

PC just to be matched with the things you need.
        
      
    

      
        
          .Gaming - This almost goes without saying, but most gamers upgrade to new


hardware every one or two years, simply to keep up with too many needs that


the newest games place on their computers.
        
      
    

      
        
          
            The bottom line
          
        
        
          : If you are using your PC for basic needs and it is serving you


well, there is no reason to upgrade it just because it's getting old, unless you


simply want to see what you're missing. If you take care of it really well


(particularly dusting inside the case), it should be for a long while:10, 15, even 20

years is not unheard of, though their level of using it goes down too much after 10


years. That said, your risk of hardware failure increases as time passes, as moving


parts get older make sure your backups are up to date, no matter how young


your computer might be.
