It can be both incredibly frustrating and incredibly damaging to your productivity when your computer is slowing down randomly.
Unfortunately, most people feel at a loss when it comes to fixing their computer and feel like there is nothing they can do to fix this problem.
Thankfully, fixing and eliminating random slowdown problems is a relatively easy matter.
Read on to discover the most common causes of a randomly slowing down computer and how to fix one.
Reasons Why Your Computer is Slowing Down Randomly There are MANY reasons why a computer will randomly run slower.

• You don't have enough free memory to run your computer properly
• You are very low on free space on your disk.
  
• You are running too many programs at once.
  
• Your computer has been infected with a virus, spyware or Trojan.
  
• You have too many temporary files or files in your various caches.
  
• Your hard drive is too fragmented to run properly.
  
• Your registry is filled with a massive amount of damaged or corrupted keys.
  This is the most common cause of random computer slowdowns.
  

How to Speed Things up When Your Computer is Slowing down Randomly Thankfully, all of the above are easy to fix.

• Upgrading memory (RAM) is a very cheap and easy thing to do, for both desktops and laptops.
  
• You should check to see if you are running out of disk space.
  If you are, then consider getting an external hard drive or some space online to store excess files.
  
• Make sure you are only ever running essential files for what your task at hand is.
  This includes ensuring there aren't any unnecessary programs running invisibly in the background.
  
• Run anti-virus once a week and have an anti-virus shield up at all times.
  
• Use a general file cleaner to empty out your cache and temporary files once a week when you run your antivirus scan.
  
• Defrag your hard drive once a month.
  Set this to start before bed and it should be done and cleaned up by the time you wake up and are ready to work again.
  

Most Importantly - Use a Registry Cleaner Religiously! The most common reason why a computer is slowing down randomly is because its registry is filled with damaged, broken and empty entries.
When these build up they create slowdown because your computer has to go through each of them to find what it's looking for.
It's kind of like picking your way through your house when you haven't cleaned it in a month (or ever!).
Getting a good registry cleaner and using it once a week to identify and eliminate registry problems is the best way to fix things when your computer is slowing down randomly.
