5 easy ways to tune up your PC

If you have noticed that your PC isn't running as fast as it did when you first brought it home, the following 5 suggestions may help you regain some of that performance. Follow the steps outlined below at least once a month to keep your PC in tip-top shape.

  1. Spyware and Adware Removal - remove unwanted and possibly harmful programs
  2. Virus Removal - detect and remove viruses
  3. Startup Programs - stop unnecessary programs from running
  4. Run Defrag and Scandisk - simple tools to keep your hard drive running smoothly
  5. Update Windows and Drivers - keep your operating system up to date

1. Spyware and Adware Removal

Spyware is any technology that aids in gathering information about a person or organization without their knowledge or explicit permission. Spyware silently transmits user information via the Internet to advertisers. In addition, Spyware will very often cause your PC to perform very poorly (slow browsing and downloads, program crashes etc).

Spyware may be found:

Bundled inside of shareware or freeware applications

In free versions of otherwise licensed applications

In peer-to-peer (P2P) and other file sharing programs

Some applications that include Spyware, are: Xupiter, Gator, SaveNow, NewDotNet, BDE Projector, HotBar, Bonzai Buddy, Comet Cursor, Morpheus, WebHancer, WinMX, Kazaa and Wild Tangent.

To remove Spyware from your computer, refer to the Tools Page where there is not only a more complete description, but several suggested utilities for Spyware removal.

2. Virus Removal

A virus can cause many problems, the least harmful (but most noticeable) of which may be decreasing the performance of your PC.

Pleas refer to the Computer Virus Page for more information on Computer Viruses and a list of utilities for locating and removing Viruses from your PC.

3. Startup Programs

taskbarMany of the programs installed on your PC may have, by default, set themselves to run each time your PC starts. These programs will take up system resources (memory, processor cycles etc) even though you're not using them. Check your system tray right after your PC starts and see how many icons are showing - this can be a good (but not definitive) indication of what's starting each time you turn on your computer.

For each of these programs, check the settings or configuration screen for a box labeled "Run at Windows Startup" (or similar). By manually starting programs as you need them, rather than having them start automatically when you turn your PC on, your start time will decrease and your system will run much faster.

It is important to note that not all programs that start on their own will have an icon in the system tray. Stopping these programs from running at start up can be a bit more difficult. Microsoft has built a program into Windows 98, 98SE, ME and XP called msconfig. This program allows you to change which programs will run when your PC starts. It is very important to note that using msconfig can cause serious problems with your PC if the wrong things are changed. It is strongly recommended that only users who are very comfortable using some of the more advanced aspects of their PC should attempt to alter settings via the msconfig utility. Some sites that will guide you in using msconfig have been provided below.

4. Run Defrag and Scandisk

Defrag and Scandisk are important utilities that come with Microsoft Windows to help you tune up your filesystem and make sure that it's running properly. Scandisk checks your hard drive to make sure there aren't any problems with it, and Defrag (short for Disk Defragmenter) organizes your filesystem to help Windows read files faster. It's a good idea to run these two utilities about once a month. Depending on your system, these utilities can take several hours to run, and may slow your system down considerably while running. It's a good idea to start them prior to going to sleep at night, or in the morning before your leave for work.

To run Scandisk in Windows XP, follow the instructions outlined below.

A. Double-click the My Computer icon on your desktop. Right-click on the drive you wish to defragment (if you have more than one hard drive, start with the C:\ drive) and select Properties


B. Select the Tools tab and then click the Check Now... button.


C. Click the Start button.


D. This process can take some time depending on the size of your hard disk, and any errors that may be found.


E. A confirmation window will appear once the scan has been completed. At this point, if any errors are found they will be displayed and you will be prompted to repair or fix them. Click OK to finish.
