How to repair your computer in your home

How to repair your computer in your home.

Need to fix your computer, but has neither the time nor money enough to take it to a professional? Do not worry, we help you solve common problems using the seven resources you probably already have in your home

Run the antivirus.

A huge proportion of modern computer problems are caused by viruses. Computers that are slowed, downloads which stagnate and some strange errors are symptoms of this scourge of modern computing.

Even if you have an antivirus program installed, that does not guarantee that it will repel all viruses before they infect your computer. As is the case with real life virus, computer viruses sometimes come to adapt sufficiently to overcome the defenses.

However, the antivirus software is constantly updated, in order to counteract the virus that emerged last week and last month, so if you run a full scan of your hard drive using your antivirus, probably find active infections.

Clean the registry.

This advice applies especially to those computers with older versions of Windows or who have had a lot of action over the last year. Every time you enter a major change in your computer, Windows updates its record. Install or remove software, change important settings, and many other things will add information to the Windows registry without you having to clean it.
But as the log is full, it tends to stop working effectively. Your computer slows down and cause errors, and you can even get to lock your computer. Luckily, cleaning your registry is an easy task and there are many programs, both free and paid, that will help you do so. One such software is not going to increase the memory of your computer, it will clean all unnecessary files, detect "malware", eliminate unused registry keys automatically update the controller, among others.

At this point, I would recommend the "Registry Mechanic", which does all the work for me. This software is amazing and has won several major awards. You can get a free scan of your computer to see how it works before you buy it.

Safe Mode.

Most people I have spoken on this subject seem to have no idea what is safe mode. Do you? The answer is that it serves to solve the major problems of Windows deactivating some default actions. Examples:
• Safe mode will prevent most programs from starting automatically, so if your problem is with one of these programs, you will discover immediately.
• Safe mode will prevent drivers from loading most of the hardware not essential, so if your hardware is malfunctioning, you will discover immediately.
• Safe mode can also help you discover the damage caused by viruses, but antivirus software is better able to cope with these problems.
To enter safe mode, hold down the F8 key when the computer starts to catch on.

Blame Windows.

Sometimes the problem is the computer's operating system, Windows. That does not necessarily mean that Microsoft is going wrong, it may be that a virus has deleted an important file. However, diagnosing a problem of Windows from Windows can be a challenge. What is needed is an external authority, I suggest Linux.
You can download a Linux CD will not install anything on your computer, but you will run the Linux while the CD (or DVD) is in the disc drive.
You can also use Ubuntu:
Go to the Ubuntu website, download the current CD or DVD, whichever you prefer (the DVD have more, but takes longer to download), write to CD or DVD and put it on your computer. Restart your computer and see if it works.

If Linux can make your computer run, then there is no problem with the hardware or Windows, so follow the following tips for how to fix your computer.

Re-install Windows.

In the days of Windows 95 and 98, people used to re-install Windows about once a year just to to keep things running smoothly.

That was the maximum progress of Windows XP, which remained stable for much longer periods. But if you have a problem with Windows can not fix it any other way, re-installing Windows is still the best option.

It is important to back up important files before re-installing Windows. If your computer can not even start Windows, you can use the method described above to use the Linux and keep your files and copy them to a DVD or an external hard drive or remove the hard drive of your computer and use a disk adapter drive to copy the files to another computer. After backing up your files, re-installing Windows should be easy. Most of today's computers allow input re-install Windows from a special menu (if you do not find that option, consult the manual of your computer).

Blowing problems.

If your computer problem is hardware, not software, you may not be able to do much. Most electronic systems can not be repaired. However, there is one thing you can do to "revive" an electronic device: blow.

Specifically, blow them to extract dust. The powder functions as an insulator, function almost exactly the same (mainly cellulose). With the dust retaining heat inside your computer, the pieces begin to fail. Most modern electronic devices are designed to work only up to about 35 degrees before shutting off automatically to prevent serious damage or even fires.
If disposing of the dust, the pieces do not get hot and you can start working again. But I warn you: the heat-damaged parts are more likely to fail than the undamaged parts, so do not expect miracles.

To remove dust from your computer (when turned off), take a tissue, cover your eyes, inhale through the handkerchief, and blow as hard as possible without spitting. If not, you could work much faster (though at a cost) using a can of compressed air you can get in a supermarket or in a business office supplies.

The last resort.

If any of the techniques described above helped you to fix your computer, in this case we suggest you ask for help. Call the manufacturer, even if the computer is out of warranty. Most manufacturers have toll-free customer support, so call will cost you nothing. The worst that can happen is that they are unable to help. On the other hand, can tell a way to repair your computer. If all these does not work at all, your last resort would be to call an accredited technician, but this will cost you some money.

Why do I need to have an EBook?

Why do I need to have an EBook?

For centuries, book lovers dreaming to have a space in your home to have hardwood libraries full of books so they can feed their love of literature. Of course not everyone can have the money and space to house the library of our dreams.
 Although for years there are different types of handheld devices that, among other functions, for viewing text documents, the reality is that they had come to meet the needs of those looking to spend some time reading, as tired end LCDs sight, preventing to enjoy a prolonged reading.
In recent times came new devices, specially designed for reading electronic books, which renewed the concept of screens, which is known as electronic ink ("electronic ink" or simply "E-Ink").

Electronic ink.

Electronic ink on the screen, unlike in the LCD, requires no backlight and has much lower power consumption. In these devices, the representation of text and images on the screen is produced by electromagnetic stimulation of tiny capsules of a matrix to form the points (white or black).
As a first highlight of the displays based on electronic ink stands that reduce eyestrain and also consume less energy. It should be noted that these devices have a rechargeable battery that gives them independence and different types of electrical connection to a computer, among which we highlight the classic USB connector.
The EBooks that use electronic ink reader on their screens are usually very thin and have a self storage unit (often with the ability to expand by standard flash memory). Its features also include the possibility of wireless (Wi-Fi, Bluetooth or 3G), keyboard (real or virtual) and audio output for viewing through voice.


Accessibility is another pillar of these devices. Having an EBook reader allows us to have hundreds of books in the physical space occupied by a magazine or newspaper paper (or less) and also run with the advantage of being able to load or acquire new with great simplicity, as these devices can connect to the computer to incorporate books or connect to online stores to buy them, in the place where we are, whether in the comfort of our home or in a hotel room, if you're on the go. Of course this is a really unmatched convenience in this regard. Notably, the EBook reader can not only display books or PDF files, but also have the ability to display text documents (DOC, HTML, RTF and TXT, etc. depending on model), images and Internet content, such as newspapers and blogs.
