How to Make Your PC as Fast as the Day you Bought It
Image via WikipediaOne of the most frustrating things in life is a slow computer.
Every few years, we buy an expensive new PC and love how fast it starts up, runs programs, and loads web sites. Inevitably, though it starts to slow down, until eventually we are pulling our hair out waiting for it to do routine tasks.
Why is this? It turns out the answer is actually quite simple and you don't even need to be "technical" to understand the causes and solutions.
The good news, it's not the computer hardware that's the problem. In most cases the hardware you have is perfectly capable of being restored to its original glory and kept in fast running condition with minimal effort.
Rather, the problem lies with changes that occur to the PC's software. The 2 most common causes of slowdown (along with easy solutions) are:
Registry errors - the most common problem
Every time you (or your kids) load a program, game or file, your PC's software registery is updated with new instructions needed to operate that item. However, when the item is removed, these instructions usually remain on your PC. Every time you run your computer it tries to execute these instructions but, because the related program can't be found, it causes a registry error. Your PC is doing a lot more work than it should be and the result is a significantly slower computer.
One of the best ways to manage this is with a neat little tool from a Seattle based company called the Advanced Registry Optimizer 2010 (ARO for short). This program scans, identifies and fixes registry errors - resulting in a computer that's a lot more like it was when you first bought it. On top of the amazing results it offers, it's so easy to install and use that it was recently awarded a coveted 4.5 star rating (out of 5) by CNET's editorial staff.
You can now get a free working version of the software which will quickly scan your entire PC and identify all of the registry errors that may be bogging it down. The free version eliminates the first 100 errors and if you have more errors that you want to clean-up or want to set the program to run on a regular basis (recommended) you can easily upgrade to the full version for just $29.95. After that registry errors will no longer be a problem.

Spyware and viruses
Spyware and viruses are software programs that are loaded on your computer without your knowledge or permission. They have various purposes, including:
- Changing the default search engine in your browser
- Tracking your web surfing habits and showing you targeted advertising
- Using your email program to send out spam to other email addresses
- Stealing your personal information
Most spyware and viruses get onto our computers through files that we download from the internet or as attachments to emails. They tend to take up a lot of computing power and as a result will significantly slow down the computer.
The simple rule of thumb to follow is to never download any free software programs from companies you do not know and trust, especially screensavers, emoticons and the like. In addition, you should never open any attachment to an email unless you are 100% certain you know and trust the sender. In addition, make sure you have a good anti-virus / spyware removal software running at all times.
Follow the above advice and your PC should stay fast and safe.
