One of the most common complaints heard by computer repair technicians is regarding slow running computers.
When these machines came out of their boxes, they were like a race horse, but only a few months later, turned into the old nag that hauled the milk cart in days gone by.
So, if your computer runs slow, you are not alone! Adding and removing many of the software programs and games that most of us use on our PC often leaves behind bits and pieces of code and data, which no longer has any use.
However these remain scattered about the hard drive and create conflicts with other programs as they may point to an action that is no longer valid.
Even removing programs through the "add and remove" option in the Windows control panel may not "safely" delete every detail of the program removed.
The best way to avoid such problems is to not let them start in the first place.
There are several things you can do to ensure that your computer will keep running as fast and efficiently as it did when you first took it out of the box.
Think of it as preventive medicine for your PC:

• Run the Defrag program weekly
• Run the Scan Disk program weekly
• Run a registry cleaning program weekly
• Delete unused or redundant programs

Each of the above named utilities can be set up to run automatically through windows.
If they are scheduled to run overnight, you will never even know they have performed their duties.
In case your computer runs slow, then these steps are the first that you must follow.
The windows registry is like a card catalog in a library, it contains all vital information on each program and each function performed by your PC.
When there are missing or redundant bits and bytes of programs, it will be trying to locate them and end up running around in circles, never finding what is missing.
This can usually be the reason that your computer runs slow.
A registry cleaner will find those missing pieces and eliminate any redundant bits of unnecessary info, smoothing out the computer's information highway, or so to speak.
It's a good idea to backup your programs before performing any "clean up" chores, just in case something vital gets thrown out in the process.
You can find registry cleanup programs by doing a Google search.
Look for one that has received some really good reviews from previous users.
Although it is possible to weed out the unwanted information in the registry yourself, this is not always a good idea.
Most computer "experts" prefer to use these automated programs as these will find things most of us just don't see.
So, now that you know what to do when your computer runs slow, you should be able to resolve these speed issues of your computer.
