You may encounter different types of errors while working on your Windows system. Let’s have a look at some of the common Windows errors and the methods to fix them.
Dynamic Link Library (DLL) files are software modules comprising executable functions and codes libraries that can be called dynamically by software applications to perform specific tasks. There are thousands of DLL files on your computer, due to which there are several reasons that may cause DLL errors on your PC. Some of the most common causes are:
- A shared DLL is overwritten (by incorrect version) or deleted.
- Malfunctioning hardware devices and software applications.
- Faulty application installation.
- Malware infections and registry problems.
To fix DLL errors caused by applications, you need to ensure that when you uninstall an application you do not remove DLLs that are shared by other applications on your system. While installing an application, be sure not to overwrite newer DLL versions. If the error is due to a hardware device, ensure that there is no problem with the device driver. To fix driver-related problems, you may either update the current driver or uninstall the current driver and reinstall it—you can do all these tasks from the Device Manager. If the driver seems fine, check the hardware for possible faults and get it repaired or replaced. Lastly, run scans to ensure that your system is free from malware infections and registry problems.
Stop errors can occur at any time—during system setup, startup or when the PC is operational. Some of the common causes of stop errors are:
- Problems in a device driver.
- Malfunctioning hardware, such as a faulty RAM chip or damaged hard disk.
- Incompatible system BIOS.
- Problems in software applications, such as Antivirus tools, backup utilities, and multimedia applications, that comprise file system drivers or services that attach to core OS files to perform various operations.
- Overheating of hardware components, such as CPU.
- Overused system resources.
- Damaged system files.
To prevent and repair stop errors, ensure that all hardware installed on your PC is in proper working condition. For instance, if you have recently installed a hardware, you can disconnect it to check if the error goes away. To prevent overheating and component damage, regularly clean up your system physically to keep it dust-free. You must always keep your hard disk free from unwanted files and applications. And you must install regular software and BIOS updates to prevent errors due to obsolete files.
VxDs or Virtual Device Drivers are used by your Windows operating system to perform operations that run in privileged CPU mode to establish communication between system hardware and internal Windows functions at lower levels. VxD Errors are caused due to:
- Older or incompatible versions of VxD files on the system.
- Missing device identifier or faulty hardware device.
- Conflicts between real-more drivers and protected-mode drivers.
- Memory conflicts.
- Errors within the Plug and Play feature.
- Faulty motherboard.
- Incorrect CMS configuration.
- Malware infections and registry errors.
To fix VxD errors, you need to find out the problem source and repair it. One way to find out the source of the problem is to start your PC in Safe Mode and check the Event Viewer from Administrative Tools Control Panel option. From Event Viewer, you will get a detailed report of the module that might be generating the VxD error on your system. Additionally, you can open the System Configuration Utility (msconfig) and use it to clean boot your system to find out the program that might be generating the VxD error.
ActiveX technology is based on the Component Object Model (COM) architecture by Microsoft and is used to create components that can be incorporated in different software applications regardless of the programming language in which they are created. ActiveX Controls are based on the ActiveX technology and are popularly used to create components that can be embedded in web pages by using the Object Linking and Embedding (OLE) technology.
Although useful, there are many inherent security lapses in ActiveX controls because of which they are frequently used for malicious purposes. Microsoft has taken several corrective steps—signing and authentication of ActiveX components and hyping up the security in Internet Explorer 7—however, in the end, the security of your system is in your hands. To prevent ActiveX errors due to security problems, you should:
- Ensure that your PC is updated with the latest security patches, hotfixes, and service packs.
- Install a firewall to block malicious ActiveX controls from infiltrating your PC and network.
- Enhance the security settings of your Internet Explorer and e-mail applications.
- Use antivirus and antispyware programs to detect and remove malware infections.
- Maintain an error-free registry.
Regular registry maintenance and malware protection go a long way in keeping your PC free from many common Windows errors. Therefore, it is good idea to invest in reliable and efficient registry cleaner, antivirus, and antispyware tools and use them regularly to scan, detect and remove unwanted information from your PC and thus maintain an error-free PC.
