It often happens that the browser cannot open some specific site, which was previously available for viewing. At the same time, it opens pages of other sites perfectly and the user does not experience any difficulties - everything is normal. It would seem that the server simply does not work - the site has been disabled. But bad luck, if suddenly you access the same site, for example from a mobile device via Opera Mobile and the site opens perfectly in it.

If the described situation is familiar to you, then I will try to answer the question: why a specific site is not accessible from your computer.

Here, for example, is the standard error that appears in the browser Google Chrome : « Sorry, Google Chrome can't open the page blah blah blah…«:

First of all, if you encounter a similar problem, you do not need to immediately follow the advice to clear the cache and delete cookies, because if you do this, you will have to re-enter the password in Odnoklassniki, remember password In contact with🙁 First, try accessing the page from other browsers, such as Firefox, I.E., Opera. If the response to the site is the same in all browsers, then try the following: go to Opera, click on the button of the same name in the upper left corner and select “Compression mode”.

This function was previously called Opera Turbo. An important feature of this mode for us is that the site opens through proxy server, that is proxy server between you and the requested site. If, when you try to open the site in this mode, the same thing happens - the page does not open, then the site is really faulty or not maintained. It is quite possible that it will be turned on after some time.

But if the site does open, then we will try to narrow down the circle of “suspects.” I’ll say right away: if you cannot access Microsoft antivirus sites, then this is 200% a virus that blocks access. Here, from personal experience, I will say that only reinstalling the system will help.

Go to the folder C:\Windows\System32\Drivers\etc and find the file there hosts. Open it with a regular notepad and check if there are any entries regarding your site in the following format:

Such entries block access to the site and are caused by spyware and viruses. Just shorten the lines regarding your site, save the file to your Desktop (be sure to select the “All files *.*” file type when saving) and copy it back to C:\Windows\System32\Drivers\etc. Restart your computer and enjoy life.

If no suspicious entries were found in the specified file, then we are dealing with a completely different reason - BANOM Your his external IP address(or range of addresses) website hosting. This is not your fault; it happens that the hosting blocks the addresses from which attempts were made hacking, DDOS attacks. Just wait until the IP is unbanned - it will take about a week.

There may also be a simple routing error. A similar problem is solved within a day or two.

Sometimes computer users may encounter unpleasant situations when something does not work for reasons unknown to them. A common situation is when there seems to be Internet access, but pages in the browser still do not open. Let's see how to solve this problem.

If the site does not launch in the browser, this is immediately obvious - a similar inscription appears in the center of the page: "The page is not available", "Cannot access the site" etc. This situation can occur for the following reasons: lack of Internet connection, problems in the computer or in the browser itself, etc. To fix such problems, you can scan your PC for viruses, make changes in the registry, hosts file, DNS server, and also pay attention to browser extensions.

Method 1: Check your Internet connection

A trivial, but very common reason that pages do not load in the browser. The first thing you need to do is check your Internet connection. An easy way is to launch any other installed browser. If the pages launch in any web browser, then there is an Internet connection.

Sometimes the system crashes, causing the necessary browser processes to close. To allow this problem, it will be enough to restart the computer.

Method 3: Check the shortcut

Many people launch their browser from a shortcut on their desktop. However, it has been noted that viruses can replace shortcuts. The next lesson talks about how to replace an old shortcut with a new one.

Method 4: Check for malware

Common reason incorrect operation browser is the action of viruses. Need to carry out full scan computer using an antivirus or special program. How to check your computer for viruses is discussed in detail in the following article.

Method 5: Cleaning extensions

Viruses can replace installed extensions in the browser. That's why good decision The problem will be removing all add-ons and reinstalling only the most necessary ones. Further steps will be shown using Google Chrome as an example.

Method 6: Use automatic parameter detection

You can also configure the proxy server in the browser itself. For example, in Google Chrome, Opera and Yandex Browser the actions will be almost the same.

In the Mozilla Firefox browser

In Internet Explorer, perform the following steps:

Method 7: Check the registry

If the above options do not help solve the problem, then you should make changes to the registry, since viruses can be registered in it. On licensed Windows record value "Appinit_DLLs" should usually be empty. If not, then it is likely that a virus is registered in its parameter.

Method 8: changes in the hosts file

Method 9: DNS server address changes

Method 10: Changes in DNS Server

So we looked at the main options for action when pages do not open in the browser, but the Internet is available. We hope your problem is now resolved.

There is probably no need to explain that situations when the computer does not boot occur quite often. There may be a myriad of reasons that led to this. Now we will try to figure out why such situations arise and how to deal with them. Let's consider exactly desktop computers, not laptops, although in some cases the methods for solving the problem may be very similar.

Causes of download problems

First of all, in the question of why the computer does not boot, you need to understand that among the main reasons there are two main ones: physical damage to components computer system and software failure (in this case Windows).

Both can cause serious problems. Let's look at the most common causes of failures and figure out how to eliminate the consequences.

Consequences of physical impact

As for damage to physical components, first you should pay attention to the initial stage of booting the PC. Probably everyone knows that when you turn on system unit makes a characteristic sound (one-time squeak). This indicates that all hardware components are in order. True, this is not always the case. The fact is that a hard drive failure is detected only after startup (the system does not see it).

Sometimes the system speaker may emit short and long squeaks. This is already worse. This can only mean one thing - any component does not work, has failed, or is simply incorrectly connected to motherboard. For different versions BIOS signals may vary. But all of them may indicate irregularities in the operation of the slats. random access memory, video cards, central processor etc. In some cases there may be no signal at all.

In this case, it is recommended to remove the system unit panel and check whether all components are connected to the motherboard. It may well be that the device does not work not because of failure, but because the corresponding cable is damaged. Naturally, it is not possible to determine such a malfunction yourself, so you will have to turn to specialists.

There are often cases when the computer does not boot even when turned on. There may also be enough reasons for this. It is very likely that there is simply no power supply. It is worth checking the outlet or uninterruptible power supply. Sometimes, when a large number of electrical appliances are plugged into an extension cord, protection and much more may be triggered. You can check the battery that is installed on the motherboard. It is very possible that after replacing it, turning on and booting the computer will go as usual. Often no one pays attention to this, nevertheless the fact remains a fact.

In general, you should immediately check all cables, sockets, extension cords, etc. Maybe this is really the reason. That’s why it turns out that nothing starts, nothing loads, the computer is black and shows no signs of life.

Crash systems

Of course, you can replace the hardware, but with the operating system itself the situation is much worse, because no one obviously wants to deal with reinstalling the system, formatting hard drive or partitions, which will result in data loss.

There are a lot of reasons for Windows crashing: a sudden power outage, incorrect shutdown or shutdown, a failure in software, the presence of viruses, damage to the hard drive, etc. The list can be endless.

As for physical damage to the hard drive, the severity of the problem can only be determined after full testing of the surface and contacts. If it burns out, you know, you’ll have to shell out money for a new one, there’s nothing you can do about it. If the damage is minor, you can try to restore bad sectors. This will be discussed a little later.

Basic methods to correct the situation

As is already clear, in terms of hardware failure, when the computer does not boot, the black screen hangs constantly, the system unit does not make a sound, the solution would be a complete test of all components. It is very possible that reconnecting or replacing some of them will clarify the problem.

It is worth noting that in some cases, when the system does not detect the hard drive, the most trivial situation may occur. In the BIOS, the boot priority can be set to, say, CD/DVD/ROM first, the second device is a USB drive, etc. It is clear that when media of this type is inserted, the system will display a message stating that this is not a system drive.

It also happens that the computer does not boot from the installation disk. Windows distribution. Here you will have to check the disk itself. It is very possible that there are some scratches or other damage on it. By the way, perhaps the drive itself is damaged and simply does not work.

Now a few words about how to correct the situation when the computer does not boot, Windows 7 does not start, and in general it seems that nothing can be done.

Let’s say right away: don’t despair and panic. Bill Gates is not a stupid person at all. When creating his system, he left loopholes to restore the functionality of the “operating systems”, and today there are quite a lot of methods that allow you to quickly and effectively apply measures that can, so to speak, breathe life into the system new life. Below we will describe the most common problems and methods for eliminating them specifically from the point of view of the Windows software shell.

Loading Last Known Good Configuration and Restoring the System

As a rule, even after very serious mistakes in Windows work 7, as they say, doesn’t just give up. On reboot (if everything is ok with boot records), testing occurs, and then in most cases a message is displayed about possible options downloads, including loading the last known known configuration.

This happens because the system, as it were, remembers its last working state and offers to go to it, bypassing all the changes made before. In 90% of cases this helps. However, it also happens that the computer does not boot even if the Windows recovery, and the user ultimately receives a message that the configuration could not be loaded.

The same applies to using system restore, which may be offered when Windows starts. Sometimes it helps, sometimes it doesn't. In principle, both services are very similar. In this state of affairs, more effective measures will have to be taken.

Safe mode

Many users, faced with a problem, for example, when the computer does not boot after updating Windows 7, clearly underestimate the benefits safe mode, but it allows you to gain access to a fully functional system and fix many software errors.

To load safe mode after the system starts, you need to press and hold the F8 key. When the system boots, we can take care of our problem. In this case, you can check all the hardware components for functionality and the presence of the appropriate drivers, run a disk check for errors, and finally begin restoring the system.

System Restore

First of all, using the control panel, you need to go to the “Backup and Restore” section. It can also be accessed from the main Start menu under All Programs/Maintenance. Here you need to choose control point(the last one created or one of those present in the list) and start the process itself. This, of course, can take quite a lot of time, but if you don’t want to reinstall, you’ll have to be patient.

Now let's say that after the updates the computer does not boot. In the same control panel, if you go to “Center Windows updates"You can view the update log, in which, in fact, you will need to delete everything that was installed before the system crash, no matter whether these updates were installed automatically or manually.

In many cases, this approach allows you to revive Windows without resorting to more serious methods, which not every user will be able to handle.

Using the Recovery Console

If the above method does not produce results, you will have to use other methods. One of the most effective and radical methods when the computer does not boot is to use the recovery console, which is available either on the Windows 7 installation or emergency recovery disk.

To use such disks, of course, you should make the appropriate boot priority settings in the BIOS, indicating the CD/DVD-ROM first in the list.

The boot menu will show a "Welcome To Setup" screen, after which you will need to press the "R" key to go directly to the console ( command line). It is worth considering that if more than one operating system is installed on the computer, folders with files will first be shown, and then a request will follow which system the user wants to work with. Now you just need to enter the number corresponding to the number of the selected system. Next, you may be asked to enter the administrator password, provided that you have one. Now about the teams. What and how to enter and what to use, we will now figure it out.

Recovering the Boot.ini file

As a rule, one of the reasons for a system crash is damage to the Boot.ini boot file, which is responsible for loading the system. To restore it, almost all systems use a tool called Bootcfg. Bootcfg/Rebuild is entered on the command line (not counting other tools for scanning its entries, redirecting actions, adding identifiers, etc.). It seems that, apart from the main recovery command, the average user does not need anything else.

Recovering the Master Boot Record

The master boot record contains tables of all logical partitions of the hard drive. The so-called primary loader places the active and boot sectors in the tables, after which, in fact, the system starts. If the boot record is damaged, the active sector simply will not be able to start the system.

To restore in this case, use the Fixmbr command, after which you enter the qualified name of the disk or partition. In the case of drive C, the command will look like Fixmbr\Device\HardDisc0.

Recovering the boot sector of the hard drive

The boot sector is a small partition on the hard drive for storing data in file systems FAT32 or NTFS for boot. If it is damaged, use the Fixboot\c: recovery command (provided that the “OS” was installed on drive C).

Quick system reinstallation

Again, let's consider a situation where, after updating Windows 7, the computer does not boot, and the system simply does not want to start. As a last resort, you can use the so-called quick reinstallation of the system in the same folder where the previous OS was installed. In some cases, this may correct errors.

After the system starts from the disk, a window will appear license agreement. You can agree to the terms by pressing the F8 key, after which you will be asked to select an installation method. "R" key - recovery existing version, Esc - cancel recovery and go to new installation. In most cases, recovery proceeds without problems.

Virus check

Now a few words about another unpleasant situation, when the system does not start and the computer does not boot. A black screen may be the result of spontaneous viruses that either prevent the system from booting or change boot records.

In this case, it is recommended to use utilities such as Kaspersky Rescue Disc or Dr. Web Rescue Disc. As is already clear, such programs start directly from optical disk, but, most interestingly, they are loaded even before the Windows OS starts. They have GUI, so working with them is not particularly difficult. It should be noted that in 99.99% of cases, such applications remove even those viruses that are simply impossible to remove using standard scanners installed on the system. After all, they can “hang” even in RAM. At the end of the check, the computer terminal is rebooted, and, hurray, the system works again as if nothing had happened.

Conclusion

So we looked at the question of what to do if the computer does not boot. It seems that some solutions to this problem will be useful to many users. Of course, it’s quite difficult to say right away, right away, why a computer or operating system won’t boot. But if you conduct a comprehensive test and find out the cause of the problem, then you can choose the most appropriate method to correct the situation.

On this page I will try to collect all the solutions known to me for the problem when pages in the browser do not load completely. Sites do not open completely. For example, some images or scripts on sites do not load. Pages in the browser are displayed crookedly, or only part of the site loads. And some sites don't open at all. Or they open, but not the first time, but the second or third time. We will look at solutions for Windows 10, 8, 7. Simply put, for computers. If you encounter this problem on mobile device, then most likely the reason is in the router (if you are connected through it). I will write more about this in the article. This is roughly what it all looks like.

I myself have encountered a problem several times when my browser did not open sites completely. For example, pictures were uploaded to VKontakte. In Odnoklassniki and others in social networks this also happens. I don’t remember exactly, but my solution was simple: clear the cache, restart the browser. There are also more serious reasons. For example, the MTU value is incorrect. This parameter can be changed in the router settings, or in Windows itself.

The most common reasons:

1. Browser glitch. As a rule, restarting the browser, restarting the computer, or clearing the browser cache helps.
2. Problem with browser add-ons. Sometimes, some add-ons installed in the browser prevent the page from loading completely. Most often, add-ons that block advertising on websites are to blame for this.
3. Incorrect MTU value. We will not understand what this is and how it affects the loading of sites, but very often because of it, sites either do not load at all or do not load completely. As I wrote above, MTU can be changed in the router settings (if the Internet is connected directly, then Windows settings) . Usually the value there is 1500. After setting 1460, everything starts to open normally. But there is no guarantee that in your case the problem is with the MTU.
4. Viruses and malware. I am sure that some viruses can prevent browsers from displaying pages normally.

I would like to note that such problems with “crooked” display of sites can be observed in all browsers: Firefox, Opera, Chrome, Yandex Browser, Microsoft Edge and even Internet Explorer. Which, even without any problems, can load sites incompletely or crookedly :)

Sites do not open completely: the first solution and search for the reason

To begin with, I recommend close the browser and restart the computer, or laptop. Perhaps everything will work great. If your Internet connection is via a router or modem, you can also reboot it. It definitely won't hurt.

Since nowadays a router is almost always installed, and all devices connect to the Internet through it, check how sites open on other devices. You can even check it on Android or iOS smartphones and tablets. But it’s better, of course, on a computer. If possible, connect your computer to another Internet. For example, to another Wi-Fi networks, which you can even distribute from your phone.

Check how everything works through another browser. Even standard. Remember, maybe you installed some add-ons or programs before this.

This way we can understand the cause of our problem and where to move next. You can describe the results of these checks and reflections in the comments. I will try to help.

Clearing the browser cache

This is one of the first solutions to try when you encounter this type of problem. I am planning a separate article on this topic, but here I will briefly show how to clear the cache in the most popular browsers.

If you have some other browser, then I think that you can easily find the cache clearing function in the settings. Or ask in the comments.

Checking browser add-ons installed

If clearing the cache did not help, and the page in the browser still does not open completely, then I recommend checking the installed add-ons and temporarily disabling them (if any).

You can also do this in the browser settings, somewhere in the “Extensions”, “Add-ons” section. For example, in the Opera browser:

Disable all installed extensions for a while.

If you don’t know where these settings are located in your browser, then look at the article. In it I showed how to manage extensions in popular browsers.

Also look at what programs you have installed and running on your computer. Maybe you'll find something suspicious.

MTU and problems with incomplete loading of sites

I already talked about this parameter above in the article. As a rule, it is changed in the router settings. Very often, due to incorrect MTU values, problems arise with displaying pages when connecting to the Internet via 3G/4G modems. When the modem is connected to the router. But this also happens with a cable connection.

You can change the MTU in the router settings, in the section with Internet connection settings: “WAN”, “Internet”.

I'll show you how to change MTU on some routers.

In the WAN section there is an item "MTU Size". By default there is 1500. You can register 1460, or even 1400.

If you have PPPoE, then you need to click on the "Advanced" button and change the value there.

Save the settings and reboot the router.

In the "Internet" section. "MTU" field.

I can't show you in detail how to do this on routers from different manufacturers. Therefore, if you don’t find these settings, write in the comments.

Virus checking and more...

If all else fails, then it would be a good idea to check your computer for viruses. You can run a scan in your antivirus (if installed), or check your system with one of the free antivirus utilities. For example, Dr.Web CureIt!.

If, when connecting to another Internet (Wi-Fi network), sites load the first time and completely, then it makes sense to call the provider’s support and explain the problem. Maybe they have some kind of problem.

You can also try on Google Public DNS.

I told everything I know about this topic on this moment. If there is new information, I will definitely add it. You can also share your observations and advice. Best wishes!

Are you having trouble loading your website? Don't worry - we're here to help you. This article will show you how to fix the problem so you can get back to surfing the Internet.

First let's determine what the problem is

With a little detective work, we can narrow down our problem.

1. Open new tab and check if you can load another website like google.com or mozilla.org.
2. Launch another browser, for example Internet Explorer or Microsoft Edge Safari Google Chrome and try opening the site you are having problems with.

The problem only occurs on certain websites

If you see one of the following error messages, it may be due to a problem with the Firefox cache:

• The connection was interrupted
• The connection was reset
• Connection timed out

Try clearing Firefox cookies and cache

Follow these steps and then reload the website you are having problems with.

If cleaning cookies and Firefox cache didn't help, this is probably a sign that the problem lies with the website itself. In this case, all you have to do is wait until the problem is fixed. With large websites like Twitter or Facebook, this can only take a few minutes.

If you don't see any of the error messages described above, check to see if your problem fits one of the specific problems listed below:

The website loads but does not work correctly

If a website doesn't look right or doesn't work the way it should, you should review the following articles:

The problem only occurs on a secure (https) website

Look at the web address in the address bar. It starts with https://(pay attention to "s")? If so, check to see if you receive the following error messages:

The problem only occurs in Firefox

If your other web browser works fine, one of the following solutions will work for you:

• Firefox can't load websites even though other browsers can - if you can view websites in other browsers but can't view them in Firefox.
• Unable to connect to websites after updating Firefox - If you are having connection problems after you update Firefox.

If you see the following error messages, Firefox is trying to access the Internet through a proxy server:

• Proxy server refuses connection
• Could not find proxy server

If you connect to the Internet through a proxy, compare Firefox settings with Internet Explorer - read the Microsoft Guide to Proxy Settings.Read the article Entering proxy settings on a Mac in Apple Support for more information about proxy settings.

To check your connection settings in Firefox:

If the problem occurs in all web browsers

This is probably a problem with your Internet connection. For some tips to resolve this issue, see the article Firefox and other browsers can't load websites.

Other, less common problems

• Website says Firefox is outdated, incompatible, or not supported- For more information, read Websites report that Firefox version is outdated or incompatible, even if it is the latest version.
• The plugin crashed- This means that the plugin used to display content on the current page quit unexpectedly. For more information, read Reporting Plugin Crashes to Help Mozilla Improve Firefox.
• Reports about malicious sites- If you see the warning "This site is suspected of attacks!" or "This site is suspected of being a scam!", Firefox has blocked access to the site you are visiting to protect you from malware or a fake site (phishing). For more information, read Phishing and Malware Protection (Mozilla.org).
• Offline mode- If you see a message about offline mode, you may need to configure Firefox not to use your network connection. Make sure your computer has a network connection and then:
