Windows Registry Tutorial: Common Causes for Computer Crashes

Have you ever lost your data because your computer chose to crash just when you were about to finish your report or some other important work?

This article covers some of the primary causes of Windows XP and Vista crashes and how you can prevent these crashes.

Large, Damaged, Fragmented Registry

Registry problems are one of the main causes of crashes on XP and Vista computers. The registry contains the configuration information that is required by all applications and devices installed on your system to operate. When your computer is operational, a large number of entries are added, removed, or accessed from the registry in a very short interval. Over time, many unwanted, obsolete, and incorrect entries accumulate in the registry causing it to grow to a very large size. A large registry easily gets damaged and fragmented and starts generating system errors, such as Exe errors, Dll errors, and driver errors on your system. If not checked in time registry problems can be fatal for your system and may even leave it unbootable.

To prevent these problems, you must regularly scan and remove unwanted data and errors from the registry. You can do this easily with the help of registry tools. Registry tools not only help you repair registry errors, but they also enable you to defrag the registry to compress and make its files contiguous.

Malware Infections

Malware programs, such as spyware, adware, viruses, and Trojans are one of the worst threats to your PC.   These programs not only cause your computer to crash, but may even cause irrecoverable damage to it.

Viruses are generally self-replicating programs that spread by adding malicious codes to program executables and documents on your system. There are a few viruses that alter existing registry entries and modify file associations to prevent applications from functioning normally on your system and generate errors such as exe errors and dll errors.

Spyware programs are different from viruses. These programs usually come packaged with other applications and stealthy install on your system. Their main purpose is to collect your PC and Web activity information and send it to external sources. In addition, these spyware programs eat up a lot of system resources and drastically slow down your PC.

To combat malware infections, you must install reliable antivirus and antispyware programs on your system. Using these programs, you must periodically scan your Windows system for malware infections. You must keep these programs updated with the latest definitions to ensure that your computer is protected against the latest malware. You may also use a registry tool to scan and remove any malicious entries missed by your antivirus and antispyware utilities.

Too Many Startup Programs

When you start your XP or Vista computer, certain programs and processes are loaded at startup. Many of these programs are critical to run your system. But, there are some that are added to the startup list by various tools and applications that you install on your computer. Since these programs are required only by the application that has added them to the startup list, they are not critical to run on your system. Therefore, it is a good idea to check your startup program list and disable any unnecessary program from loading at system startup. This will help you free up system resources being consumed by these programs and enable you to improve the performance of your PC.

You can check and remove unwanted startup programs from the Startup list (Start menu) or disable them by using the System Configuration (msconfig) utility. Many advanced Registry Cleaner programs also include a startup program management feature. You can easily use this feature to disable all unnecessary programs from loading on your system at startup.

Registry problems, malware infections, and too many programs running unnecessarily on your system are major causes of system crashes. As a vigilant user, take appropriate actions to prevent these problems and save your PC from frequent crashes.
