Common Windows Computer Problems and Solutions

Computer Aid Posted on by

A computer can encounter many errors in its usual course of function, the nature of which can be attributed either to hardware or software. If you happen to face a hardware error—for instance, if the system refuses to boot up—you will need to consult a specialist and perhaps get the erroneous hardware replaced. However, if it is a software error you are facing, like error 1402, you don’t need to seek the help of an expert, no matter what the various computer magazines and websites might say.

Truth be told, it is very easy to deal with most computer errors on your own, no matter what your skill level.

What causes computer errors:

Errors are caused by various factors, and it is not possible to discuss all of them. However, we will list some examples. Take the rather common msvcp71.dll error. A little research will show that this error is related to the Visual C++ application and is caused when there is an error related to a DLL.

There are also countless of other reasons why you might encounter PC errors: missing files, broken codes, viruses, corrupted file systems, etc., which can cause various error messages and further confuse users.

Dealing with computer errors:

No matter what the error, you don’t have to be a rocket scienctist to deal with them. Just follow the simple steps listed below.

  • Registry cleanup – The registry is a very important part of the Windows system. It can be understood as a master database with a complex indexing system that stores all the information about your programs and settings. But one needs to take care of the registry regularly, as complicated system errors like the ogacheckcontrol.dll error can take place. Invest in a good registry cleaner, so that it can automatically scan and fix the registry as and when required. The operation will be very easy to perform and can be done in a few mouse clicks.
  • Program management – It is common knowledge that new systems replace old ones, and that both can rarely coexist. So is the case with programs that reside on your computer. Very old programs are useless. They not only take up unnecessary disk space, but also cause conflicts during execution and bring up errors when they don’t locate old files that they were designed to work with. You can either remove them yourself, or get a freeware program to suggest which installed programs can be removed.
  • Malware removal – Malware is the collective term for various malicious programs, and are often responsible for numerous errors commonly found in the computer. You should make sure that all of your protective programs are up to date and not subject to harmful malware.

As this article has shown, by following the simple steps mentioned above you can keep your system error free for a long time.

What You Should Know about Windows File Extensions and Issues Related to Them

While some parts of a Windows system are well understood, others are not. For instance, there is a lot of awareness about the various types of viruses and the ways to prevent infection, but not much is known about the different types of files on a computer and errors related to them. Therefore, this article will provide a short introduction to the various types of Windows file extensions, as well as the errors that can be encountered.

What is a file extension?

A file extension is the three-letter part of a filename. It is usually preceded by a dot, and is used by the operating system for a variety of purposes. For instance, text files are named in the following manner, ‘mycontacts.txt’, in which case the ‘.txt’ part of the filename is the file extension, which says that this file will comprise plain text and can be worked on by a text editor like Notepad.

Can you provide some more interesting examples of file extensions?

Sure, and there are many types of file extensions, perhaps even innumerable. Most likely you are familiar with MS-Word files or PDF files because there is a good chance that you work with these files on a daily basis.  However, there are a large number of file types that you may not be familiar with.  We will now discuss some of the lesser known file extensions:

  • .bup file extension – This file extension is related to DVDs. A .bup file is generated by a DVD player, and it is the backup file for another type of file created by the DVD player, called the IFO file.
  • .mui file extension – This file is used by the Windows to define the language settings for the interface. The acronym stands for MultiLanguage User Interface, and provides the ability to customise the language according to the user.
  • .dat file extension – This extension serves two purposes: sometimes it works as a binary file for storing data in the most basic format, and is also the format for some videos on the Windows platform.

What causes file extension errors?

There can be many reasons, some of which are listed below:

  • The registry might be corrupt.
  • The filesystem may be corrupt.
  • There might be malware infection.
  • The platform might be wrong for the file.
  • The required application might be missing.

What do I do to avoid such errors in the future?

There are many things you can do, and we describe them below:

  • Registry cleanup – The registry stores a lot of information on file types, and so it is important to ensure that it is not suffering from any problems. Therefore, you should purchase a good registry cleaner and scan your registry periodically to avoid file type errors.
  • Malware scan – Many times, malware are responsible for various types of errors. Therefore, you should have all the required protective software installed on your system and update it regularly by connecting it to the internet.

Steps to Follow when Repairing Computer Errors

Computer Aid Posted on by

While computer errors can never cease to trouble you, you can definitely do something conclusive about them. Contrary to what people commonly believe, it is possible to deal with most of the common PC errors on your own, such as the 0x0000000a error that occurs due to a hardware malfunction; the msvcr71.dll download error, which is a usual DLL error that occurs when this particular file is missing or corrupt; and the sndvol32.exe download error that occurs due to some problems with the audio drivers.

We now suggest some methods that you can follow to ensure that your PC remains free from most of these errors:

  • Perform regular registry cleanups – If your registry is not functioning properly, it reflects in an overall decrease in system performance. It might lead to anything from application crashes to fatal system errors. This happens because the registry deteriorates over time, and the outdated entries for programs that no longer exist cause conflict with the present system settings, and can lead to frequent error messages and system crashes.In order to remedy this situation, you need to invest in a good, professional-quality registry cleaner, even if it costs you more initially. These tools are amazing and provide complete maintenance support. But make sure you download these programs only from a trusted source.
  • Driver update – Driver-related errors are known to occur due to the existence of obsolete drivers on the system. Yes, even though you might be surprised by this, the truth of the matter is that something as low-level as system drivers also need to be, and should be, updated.The advantages are twofold: first, the drivers will no more come into conflict, and the system will perform smoothly; and second, you will notice a significant increase in hardware performance.

    As incredible as it sounds, the same hardware can be made to perform far better and faster with the help of newer drivers. For this, you should look for a reliable third-party driver-update tool, which will automate the whole process for you.

  • Defragment the hard disk – Your hard drive can be compared to a beehive, with certain cells filled with information and others not. For better performance, we ideally want all the information cells to be contiguously located. This process is termed defragmentation, and can be easily performed by running the standard Windows Disk Defragmenter utility. It might even help you save a bit of disk space as a part of regular housekeeping.The best part is that you need not do anything except click the mouse a few times. Once the process is complete, you will find your system responding faster, as it has to spend less ‘effort’ trying to locate where all the information bits lie.

Solving common PC errors is not only easy once you have the right tools, the resulting knowledge and insight can be intellectually rewarding as well. We encourage you to go ahead and try the steps listed here, and see the improvements for yourself.

Causes And Solutions To DLL Errors

Computer Aid Posted on by

According to a famous computer journal, DLL errors are among the most frequently encountered application errors on Windows computers. However, only 5% of users are aware of what the term DLL stands for and have absolutely no idea how these errors crop up. Therefore, it is not surprising that a majority of users do not have any solutions to these problems.

The truth is that DLL errors are one of the easiest computer errors to solve and there is no need to get intimidated by them. This article will help you understand DLL files, the root causes behind these errors and finally simple solutions to get rid of them.

What is a DLL file?

A DLL file contains codes that allow it to perform specific functions. A single DLL file can be used by multiple applications that need to perform the same functions. On a single PC there are an innumerable number of DLLs present. Therefore, it is not surprising that every now and then a DLL error surfaces on your computer.

Causes and Solutions to DLL Errors

Listed below are common causes of DLL errors, such as the msvcr80.dll, msvbvm60.dll, and msvcp71.dll errors and their solutions.

Missing DLL file

The majority of DLL errors occur when a DLL file is missing from your computer. Discussed below are reasons due to which a DLL file may go missing and the steps you can follow to rectify the issue.

  • Removal of the DLL file by mistake

    If you have removed a DLL file, such as the msvbvm60.dll file by mistake, check the contents of your Recycle Bin and restore the file from there. If you have also removed the DLL file from the Recycle Bin, use a reliable third-party recovery tool to restore the DLL file.

  • Removal of the DLL file during unisntallation of a program

    Incorrect unisntallation of a program may cause a shared DLL to go missing. If this is the case, reinstall the removed program and then uninstall it again. You should always use either the built-in Add or Remove Programs utility or a third-party tool to uninstall programs from your computer.

    If the reason for the missing DLL is other than the two reasons discussed above, you may download the missing DLL file from a reliable online free DLL Directory and copy it to its location on the hard disk.

  • Overwriting of a current version of a DLL file by an older version

    When you install an old version of software, a current version of the DLL file may get overwritten with an older version. This results in DLL errors due to a compatibility issue. To rectify the issue, either install the latest version of the software or download the latest version of the DLL from the Internet.

  • Usage of outdated drivers

    Outdated driver files may also lead to DLL errors. Update your drivers regularly to avoid DLL errors occurring due to driver problems. You may use a reliable driver scanner tool to ensure that all your drivers are up-to-date.

  • Malware infection

    Malware programs corrupt your DLL files and cause recurring DLL errors, such as msvcr80.dll and msvcp71.dll errors. Run a malware scan on your computer, using advanced antivirus and antispyware tools to fix DLL issues occurring due to these malicious programs.

  • Corrupt and unhealthy registry

    It is no secret that a corrupt registry causes various system errors, including DLL errors. It is imperative that you keep your registry clean and healthy. You can achieve this by scheduling regular registry scans using efficient registry cleaning software.

Best Ways To Handle Recurring EXE Errors

Computer Aid Posted on by

Recurring errors not only cause frustration but also result in a huge loss of productivity.

An odd computer error here or there is nothing to worry over. However, the issue of recurring errors needs to be dealt with immediately.

To resolve recurring computer errors, you can incorporate either one of two strategies – seek a computer expert’s help or take the job on yourself and attempt to resolve the errors on your own. The second strategy is not only favorable to your pocket, but also helps you increase your computer knowledge and ability to deal with PC errors in the future.

The purpose of this article is to teach you how to handle recurring exe errors, such as the sprtsvc.exe error, sprtcmd.exe error, and the svchost.exe error.

Run a malware scan

Malware programs, such as viruses, spyware, trojans, and adware are often found to be the root cause of exe errors, such as the sprtsvc.exe error or svchost.exe error. Malicious programs are known to modify registry settings of exe files, and as a result, an exe error may occur whenever the infected file is executed.

The first thing you need to do when you encounter an exe error is to run a malware scan using robust antimalware software. Also, to avoid exe errors in the future, it is imperative that you keep your PC protected from the latest malware. To achieve this, regularly update your security program with the latest malware definitions and security updates.

Install any hotfixes available

In case the exe file mentioned in the error message is a Windows file, it will be prudent for you to visit the Microsoft database to see if Microsoft provides a hotfix for the error you are facing.

Update your software

If the exe file listed in the error message is a non-Windows file, then you may begin the troubleshooting process by first checking to see if any new updates are available for the third-party application that is generating the error. Outdated program files are a major cause of exe errors. To check for and download new updates, visit the application manufacturer’s website and download new updates, if available.

If you find you are using the latest software version, uninstall the program and reinstall it. Exe errors may occur if one or more files of an application are missing or damaged. This issue can be resolved when you reinstall the application because when you reinstall the application all files related to it are re-installed on your computer.

Also check to see if the exe file that is generating the error is associated with an essential program or not. In case you find that the program is non-essential, you may choose to uninstall it to get rid of the exe error. For instance, the sprtcmd.exe file is associated with programs, such as “DSL Help Center” or “SupportSoft Online Help Tool”, which are non-essential programs. So, if you are facing recurring sprtcmd.exe issues, you may opt to uninstall these programs to resolve the issue.

Run a registry scan

If the exe error still persists, turn to the registry for answers. An unhealthy or bloated registry may cause recurring exe issues on your computer. Clean your registry using a reliable and easy to use registry cleaning tool to fix exe errors that are occurring due to registry issues.

Error: “Could Not Find the File Hpzr3207.dll on the HP CD”.

This occurs when you try to install the Hpzr3207.dll (an HP printer driver) on your computer. Conflicts between the language of the driver you are installing and the regional settings of your computer is behind this error. So you would need to ensure that the language of the driver and your regional settings match by doing one of the two methods below.

On the first method, We go to Start, then Control Panel and select the Regional and Language Options option to change the regional and language settings of your computer to match the language of the printer driver. After doing so, you must reinstall the driver. If that does not work, you can do the second method by opening the HP Website of your region or country and download the driver in your computer’s language to resolve the error.

Registry problems and malware infections may also cause printer errors. Therefore, it is a good idea to run a registry scan using a registry cleaner tool to detect and repair registry errors and to perform a full system scan using an updated antivirus and antispyware tool to ensure that your system is free of all malware information.
