With the popularity of the personal computer rising everyday obtaining some basic technical computer repair skills can be very beneficial. When you first buy your computer it runs extremely smooth but as time goes on and your usage of your computer increases you may begin to notice a change its overall performance.

The power of present day computers is amazing, although they do have their problems and if you don’t know how to fix computer errors when they present themselves you can become very inconvenienced. Computers do require regular maintenance and they need to be periodically upgraded and if you fail to keep up with some easy maintenance you will no doubt experience problems. There are a few simple tasks that can be performed to fix computer errors and help prevent them from occurring in the future.

Tips That Will Help You Fix Computer Errors

If your computers registry becomes corrupt or unstable it will dramatically affect your computers performance in a very negative way. You may notice your computer is running extremely slow and your having to wait for programs to open or it takes awhile to switch from web page to web page. If you use your computer for work or school or maybe just to run the family’s budget, learning how to fix computer errors when they occur can be extremely beneficial.

When your computers registry has been corrupted you may have error messages popping up on your screen such as “fatal .exe error” or “.dll file error” and these type of errors can cause your system to shut down or freeze up leaving you with a computer that you cannot use. When these type of errors occur it can be extremely frustrating because you may be in the middle of some important work, so if your learn how to fix computer errors such as these you can avoid serious down time.

One of the first steps you should take in efforts to solve your problem would be to run your disk defragmenter. Running the disk defragmenter may reduce the occurrence of errors by condensing all the files in need of repair.

To fix computer errors that are related to your computers registry, you should complete a registry scan so that all the unused, old and unwanted data can be detected and removed. To clean your computers registry you will need to “BUY” a good registry cleaner program. I want to emphasize on the word “Buy” because there are a lot of free registry cleaners available but it’s a terrible idea to even try a free registry cleaner. Free registry cleaners will not only just not fix computer errors they will cause damage to your system. When it comes to the free registry cleaners the programmers will put in malicious code and adware and spyware programs that will collect and transmit your personal information and in many cases end up leaving your computer so damaged that it cannot be repaired.

Reg Clean is one of the more advanced registry cleaner programs available as it can perform a variety of preventative maintenance tasks as well as removing malicious spyware and viruses that have infected your registry. When you run a scan with Reg Clean it can fix computer errors as it cleans up your entire registry and it performs a registry backup while it is defragging your system.

There are a number of viruses out there that can really attack your system causing all sorts of problems. Spyware and virus programs can be the cause of a variety of computer errors. They are capable of overwriting program files or deleting necessary file extensions disabling important programs and limiting the functionality of your system. To fix computer errors that are a result of spyware and some viruses you can use updated antispyware and antivirus protection.

Damaged or corrupt programs or virus infections can cause serious damage to your computers boot section, and this will prevent your system from booting up properly or possibly not at all. When you need to fix computer errors related to your system booting up properly you should use your Windows XP Boot CD as this can repair the Windows XP installation which can overwrite computer errors picked up through spyware or viruses.

If the problems that you are having are directly related to your computers memory you will experience some of the following problems; system crashes, system hang or computer freeze, blue screen, constant restarts and crashing software programs. To fix computer errors related to your systems memory there are specific software programs that can help free up some memory space which will help solve RAM related problems. Improving your systems memory which is also known as RAM (random access memory), will improve your computers performance dramatically so I would highly advice you to do a computer memory test. To complete a memory test there is specific software available for such a task, one program that I am aware of that is very effective is called Memtest86, this can help you zero in on your problem allowing you to fix computer errors brought to your attention through the use of the software.

If you have tried all the advice given in this article and your still experiencing computer problems I would do a search on the Internet for information on how to fix computer errors. You will find many websites that focus on computer basics and troubleshooting. I would be very careful though and really check the websites credentials so you can be sure that your getting advice from a reliable and secure source. There is also a software program available that can help you learn how to fix computer errors, but again I would be very cautious about any program that needs to be down loaded and run on your computer. Remember preventative maintenance can save you from a lot of unnecessary problems and one of the best preventative measures you can take is to purchase a reputable registry cleaner program and use it periodically to clean your registry of old, unused, unwanted and damaging data.

Spyware is malicious software (malware) that installs itself or runs on your computer without providing you with adequate notice, consent or control. It can monitor your online behaviour or collect your sensitive personal information such as personally identifiable information and passwords. It could as well display annoying pop-up advertisements, change your computer settings or cause your computer to run slowly. Because spyware does not obtain your consent before installing or running on your computer, and may not immediately display any noticeable symptoms after it infects your computer, you might not actually be aware of its presence in your PC.
 
Spyware and other malware are most commonly installed through free software downloads, such as file sharing, screen savers and search toolbars. Also, they could be installed by websites, downloaded programs, or software you might install from a CD, DVD, external hard disk, or other removable media. Some spyware can be installed from a website through an embedded script, or program in a webpage while some potentially unwanted software require your help to install through web pop-ups or free software that requires you to accept a downloadable file. In other words, you can get spyware installed in your computer without knowing it.
 
Let us take a look at the signs you should look out for to know if your computer has been infected by spyware or other malware:

1.    If you notice new toolbars, links, favourites or bookmarked web pages, which you did not intentionally add to your web browser, you should know that spyware has sneaked into your computer.
2.    When your default homepage, mouse pointer or search program changes without your intervention, it indicates the presence of spyware.
3.    If you typed the URL for a specific website (for instance, a search engine), but you are redirected to another web site without notice, is a typical action of potentially unwanted software.
4.    If pop-up advertisements are constantly displayed on your screen, even when you are not currently working on the internet, your spyware alarm should be set off.
5.    Spyware may also cause your computer to suddenly start to run very slowly.
 
It is possible to not have any of these symptoms but yet, your computer might still be infected by spyware. You are therefore expected to take proactive steps to keep this form of malware at bay. By diligently taking the actions below, you are ensuring that you protect your computer from spyware infection:

 Run Up to Date Anti-Spyware Software – anti spyware software helps prevent malicious software, spyware, and other potentially unwanted software or adware from installing itself or running on your computer. Antispyware program can also perform a computer scan to locate and automatically remove malware that might already be installed on your PC.

Windows Defender is a version of anti-malware software that is shipped together with windows operating system but there are other sources of anti spyware software including those which are customizable to handle all forms of malicious software.

 Keep Your Computer Up to Date – always update the security features of your computer. To do this automatically, you need to turn your windows automatic updater on at all times. Similarly, you must visit your anti-spyware software publisher’s website often to check for and download updates of your software, to your computer.

 Review License Agreements Before Installing Software – before you download any free software such as file sharing programs or screen savers, please read the license agreement carefully. Do not automatically agree to download any software offered by any website; rather look out for clauses where you might be required to accept advertisements and pop-ups from the company. In some instances, the software publisher may require you to agree that the program will send certain kinds of information back to them. In such cases, if you do not trust the website, refuse to download such software to avoid installing spyware in your computer.

 When Pop-Up Won’t Close Except You Take An Action – sometimes a website could repeatedly display pop-ups asking you to install a toolbar, change your home page or take other similar action. The first action to take on such a situation is to try to close the pop-up browser window, if the pop-up still appears, right-click the internet explorer button in the task bar at the bottom of your screen and then click close group. If every effort to close the pop-up window fails, as a last resort, close any other program you have open and restart your computer. 
No effort should be spared in getting rid of spyware because of the enormous threat it poses to the health and efficiency of your PC and your online safety. I strongly recommend that you follow these simple steps diligently to achieve the desired results.

How long have you own your computer? 1 month? 1 year or many years? Regardless how long you own your computer, it is extremely important to have a very good backup system. I’m sure all of us got many collections of files and folders stored in the computer’s hard drive. Some of us may have thousands of songs and movies (illegally not to mention but who doesn’t :p) downloaded from numerous sources on the net and full archive of photos from 5 to 15 years ago. Have you ever imagined if someday your hard drive crashed or fried by overheating or stolen (happened to a famous movie director)? What will you do? You might try to recover your drive but the success is not guaranteed though (if you got 50% recovery you’re lucky enough). But what if you’re out of luck? You gonna lose all of your data! All of your collection of files will be gone. Whatever you have on your hard drive I’m sure you can’t afford to lose them. That’s why everyone must have a good backup system.

How are backups being done?

Backup is simply means having the extra copy of files stored inside the computer’s hard drive elsewhere. There are few ways of how backup can be done. The simplest way of doing backup is having an external hard drive when you can store all of your data in it. You can also upload them to online file hosting services or having your multiple drives at RAID 1 configuration (may require advance knowledge on computing so it won’t be discussed here).

1) Online file hosting.

Online file hosting means hosting or keeping files online. Keeping files on the net doesn’t necessarily mean it is freely available for every internet user. You can save your files privately or share them with anyone who has the access to the internet. There are tons of online file hosting services freely available to use. I’m sure you’ve heard about RapidShahre, SaveFile or BoxNet. These are a few example of site that offers free online file hosting while at the same time also offering file sharing. I’ve personally use some but Orbitfiles is the only one I’m sticking with until now. It offers 6 Gigabytes of storage for free. Orbitfiles users can also share or even sell them (assuming you have full rights on ‘em)! To host your files online, you will need to upload them to the server.

Most of the services use internet interface to upload file like you do when uploading photos and videos to Blogger or Wordpress. Some of them also provide free application software for easy uploading process. Orbitfiles users can download free software called Hercules uploader which is very handy to upload your files to the server. You can schedule the uploading process to be at 3:00 am every morning or 2:00 pm every Monday. It is free and easy to use. I use online file hosting only for important and small files. Small files are much faster to upload than larger files. If you need security for your files, you can password protect your files using Winrar. A simple .zip or .rar file with a strong encryption (password) is almost impossible to be opened without the correct password. Even with a good computer, you’ll need years to break the code using bruteforce attack. You can click the link below to visit Orbitfiles website.

2) External Hard Drives

The easiest way to do backup is by having an external hard drive. External hard drives have become the most popular option for either extra storage space or backup purposes. Year by year the price of hard drive dropped quite rapidly. External hard drives come with a wide range of capacity from old 8 Gigabytes to 2 Terabytes (1 Terabytes = 1000 Gigabytes). 2TB had drives are still expensive at the moment. An external with descent capacity (160GB – 500GB) is just nice for backup purposes. They are not that expensive as 2TB. Once you have one, you can start backing up your files. However to do it in regular basis is quite boring and after some times you won’t care about you backup anymore. Some external hard drives come with its own backup software which is doing the boring part for you. I have one Seagate hard drive that comes with a program call drive manager where you can set the files or folders to be backed up automatically at any time 7 days a week. If the program detects any change of files in your selected folder, it will update your backup folder on external hard drive on the next scheduled time. You can also disable auto backup if you prefer that way. Remember this, computers and hardware can be insured, but the only insurance for data is backup!
