Is your computer running slow? Have you been waiting and waiting for your PC to boot up, and then you wait and wait for the windows to open while you tap your fingers with impatience, maybe you walk in circles around the offending machine, casting furtive glances at the screen, fantasizing that it will speed up if it believes you're not watching, this is truly frustrating.

This frustrating waiting game is a symptom of a common problem; plain and simple, the registry on your computer is running slow. There are many possible reasons for the 'computer running slow" disorder. However, chances are your sluggish desktop/notebook is suffering from one of the most prevalent afflictions.

There are four of them. And the causes and cures for each of these follow:

Coming in at number one our list is the VIRUS. A virus may be the root of your 'computer running slow' syndrome, and it's possible that it has more than one virus, in fact. Never fear, the fix is an easy one; you should have anti-virus software installed on your computer.

It's also a good idea to schedule regular automated checks, which you can do with any good anti-virus application. If you can't find the anti-virus tool, then get one, quickly. There are some very good packages available at no charge. Among them are Panda, AVG Free and McAfee.

The second most common reason for 'computer running slow' syndrome is Spyware/Adware. These are both software programs installed on your computer, probably without your approval. They enter through your internet door when you and your PC are web surfing. Spyware and adware are designed to gather personal information about you, like which websites you visit, but they can be more malicious. Install and use A-Squared anti-adware to remove these.

In third place, we have lack of RAM: Your PC may be suffering the 'computer running slow' condition because it needs more random access memory. RAM is more commonly referred to as memory. Your PC is designed to permanently store a lot of information on the hard drive, but the work you do in the present, like unsaved spreadsheet calculations reside on the RAM, until you permanently save them.

If you don't have enough memory, then your PC goes into overdrive to get the information you need.

Last but not least in our top four, is damage to your computer's Windows Registry: The Registry is a database that contains information about your PC's hardware and software. If the Registry is impaired, it could definitely cause 'computer running slowly' issue. Don't let the idea of the Registry scare you. There is software available to help you get that database back into shape.

In conclusion; a registry cleaner software will definitely cleanup a computer from errors that often cause it to crashes, freezes, and make the applications and tasks run slower than they are supposed to. A good register cleaner software will scan and restore your pc, optimize performance, protect your computer, make it run faster as well as others basic functions.
