What to do if the reasons are in the computer itself
There are various reasons why the Internet browser cannot open web pages. Often this is due to the inability to establish a connection with the servers. However, there are other technical problems as well. In any case, in order for the browser to work normally, you will need to identify the root cause of the error and eliminate it. Let's take a closer look at how to do this.
Internet connection problems
Despite the fact that it seems obvious, many users forget that problems with opening web pages can be related to the lack of an Internet connection. First, see if there is a connection. This can be done by clicking on the antenna icon in the lower right corner of the screen.
If this is the problem, try the following steps. In the case when the connection is made directly through the cable to the computer, remove and insert the cable back. If you have a router, then check if the wires have come off and then reboot the device. For a 3G modem, you need to see if it is fully inserted into the USB connector. After all the above steps, restart your computer and try to restore the connection again.
What to do if the reasons are in the computer itself
There are situations when programs on the computer download updates, ICQ and Skype work, in other words, there is a connection, but the Internet browser does not open sites. Let's see what to do if the Chrome, Mozilla or other browser does not open. The reason for this situation may be a virus that you “picked up” on not very trustworthy sites. The main thing to do in this case is to install an antivirus program, with which you need to scan the entire system. In case the antivirus cannot remove some viruses, then be aware that there are several.
In addition, you should pay attention to the hosts file on the computer. In order to find it, you should go to My Computer - Drive C. Next, select the windows folder, and in it go to the system32 tab. Here we click on the links drivers - etc. The hosts file is opened using regular Notepad or any text editor. It should only contain lines beginning with # and 127.0.0.1 localhost. Any other inscriptions can be safely erased. By the way, this file can be used to prohibit access from a computer to any site.
Other reasons
Now let's look at what to do if the Yandex browser or any other browser does not open, for some other reason. For example, error 105 appears, stating that the DNS address of the server cannot be resolved. It happens that the main problem lies in the computer settings, which we will now try to fix.
First you need to look at the network connection settings. Here it is desirable to set the ability to receive IP automatically. Since in our case the problem is with DNS, you can try to change the information in this section. For example, write the following data here: 8.8.8.8. - 8.8.4.4. Next, restart the computer and try to open the browser again. If the pages start loading - great, we found the problem, if not - we look further.
You can check the functionality of the browser itself. To do this, you need to disable all extensions in it. Each Internet browser has its own settings. Usually this menu is Extensions, Tools or Add-ons. After you change the settings, you will need to restart your computer and try to open Internet pages again.
I hope that my advice will be useful to you, and you will be able to cope with the problem. If not, then continue to further search for the reason why your pages are not loading in the browser. It is quite possible that it will be quite easy to eliminate them, and you will again be able to easily access the Internet in search of the necessary information.
