When the computer boots, there are two green bars. What to do if vertical stripes appear on the monitor

Monitor – essential device for working with a computer, which allows you to see all the actions on the screen. Unfortunately, the monitor is not always pleasing with its correct operation. Below we will look at what causes the problem when images appear on the monitor. vertical stripes, and whether anything can be done about it.
As a rule, suddenly appearing vertical stripes on the screen of users’ computers occur for two groups of reasons: software and hardware. In the first case, everything was to blame software installed on the computer, and in the second - problems with the monitor itself or its connection to the system unit.

A little advice: before you start moving on to ways to solve the problem, try connecting your monitor to another computer - this way you can understand whether the problem is the computer itself, or a malfunction in the monitor.

Software problems

Reason 1: missing video card drivers

If you just reinstalled Windows or updated your video card drivers, but then encountered vertical stripes on your monitor screen, you can assume there are problems with the drivers.

To resolve this issue you will need to install fresh drivers video cards. First of all, open the menu "Control Panel" and go to the section "System".

In the left area of ​​the window, click on the item "Device Manager".

Expand the tab "Video adapters". If next to it is the name “VGA adapter” or the name of your video card, but with a yellow exclamation point, this indicates that the drivers are not working. If the drivers have been installed, click on the graphics adapter right click mouse and in the displayed context menu select item "Delete".

A confirmation window will appear on the screen, where you will need to check the box next to "Uninstall driver programs for this device".

Once the removal is completed successfully, you will need to restart your computer. From now on, you can start downloading and installing the latest version of video card drivers (if you have already Windows installations did not work with video card drivers, you will need to immediately proceed to download them, without the preliminary removal procedure described above).

You can download video card drivers from the official website of your manufacturer graphics adapter(specifically for your model). If you are the owner of a laptop, then download graphics drivers will be performed from the laptop manufacturer's website.

By downloading required distribution drivers, you will need to run it by installing it like any other program, and then be sure to restart your computer.

Reason 2: incorrect resolution settings

The problem with vertical stripes may arise because the computer settings are set to the wrong resolution.

To check this, right-click on any free area of ​​the desktop and select the item from the context menu that appears. "Display Options".

Please note that further actions reviewed at Windows example 10. If you have a different version operating system, then the name and location of the settings may be different.

In the settings window that appears, click the button « Additional options screen".

Hardware problems

Reason 3: video card failure

If possible, connect your monitor to any other computer. If the vertical stripes have disappeared but you don't suspect software problems, we can assume that the problem lies in the video card, which could have failed.

Next, you will need to disconnect the video card from your computer, and then insert it into another computer that you are completely confident in its functionality. If the situation with the monitor is similar, you have once again confirmed your guess.

In this case, you will need to try to visually inspect the video card to see if it is covered in dust, and if the contacts are dirty. If the problem is in the contacts, clean them with an eraser and also get rid of all visible dirt. After this, the video card did not work? Then you will not be able to help her in any way: either contact service center to repair it, or replace the video card.

Reason 4: Incorrect monitor connection

Check whether your monitor is connected to the computer correctly: the cable connecting the monitor must be fully plugged in on both sides. We recommend that you additionally use a different outlet for the monitor - it is quite possible that it simply does not have enough power.

If there is any type of damage on the connected cable, the cable must be replaced.

Reason 5: Motherboard failure

Sudden power surge severe overheating or a simple manufacturing defect can cause the motherboard to fail.

In this case, of course, if you connect the monitor to another computer, it will work fine. Excluding problems with the video card, it is worth suspecting motherboard– and here everything is already sad, and you won’t be able to help her on your own; you will definitely need to contact the service center (and the sooner the better).

Reason 6: Monitor malfunction

If on other computers the monitor still produces the same reaction with vertical stripes, we can assume that the problem lies in the monitor itself.

Alternatively, try pressing top part monitor with your finger - if the stripes disappear, this may indicate that a cable is coming off the matrix body in the monitor (but this step may not work).

IN in this case, you will need to take the monitor itself directly to a service center, where they can more accurately diagnose and solve the cause of the problem, or try to disassemble it yourself (of course, if you have at least some experience). If the problem is insufficient contact of the cable with the matrix body, you will need to use something to seal the gasket at the exit point.

As a rule, these are the main reasons for the appearance of vertical stripes on the monitor.

Hello dear friends! As you can see, I haven’t written anything on the blog for a long time, because I was very busy with other work, and the computer didn’t turn on for several days. And today, Sunday, I think I’ll do a little work online. As usual, I turn on the computer and then it starts. First, immediately after starting the computer, on the BIOS splash screen appeared on the screen strange stripes, then when checking the BSOD appeared on the entire screen dollar signs, and at the end the blue screen of death with error 0X000000A5.

That's how things are, this article with own experience, although sad :(. Then everything is in order and with photographs.

I observed the picture from the very beginning, I will immediately say that almost every reboot it was different.

First, the screensaver appears and it was full of some kind of interference, as if there were problems with the video card, by the way, I have it integrated. Sorry I didn’t take a photo of this screensaver.

Then a window appears with a BSOD check, well, when the cursor at the top blinks on a black background, this cursor blinked for me, but the background was not black, but covered in dollar signs! How this can be, I still can’t understand, if you know. then write to me in the comments. After all, at this stage even Windows is loading. By the way, then instead of these dollar signs there were also different stripes. Here's confirmation :).

And then hop and that’s it, blue screen of death with error 0X000000A5.

How I solved the problem with stripes on the screen and error 0X000000A5

I immediately began to think what was what. This means that the problems with Windows were eliminated immediately, since stripes on the screen and dollar signs appeared before loading Windows 7. I checked VGA cable. Due to error 0X000000A5 Google didn’t tell me anything useful. I reset the BIOS settings to standard, well, just in case.

I immediately wanted to try installing another video card, but this error code does not seem to indicate problems with the video, so I put this idea aside for now. But still, the blue screen and bars during loading were somehow connected, well, if you think about it logically.

Based on my observations, I immediately went to RAM. I took it off, cleaned it and put it back in place, checked the wires in the middle and tried to turn it on. I’ve already connected it to another monitor, mouse, etc. (it’s just easier to connect there). And everything worked, the computer booted without any stripes and blue screens. Well, I think it’s good, I’ve even lost the desire to throw it out the window :).

Then I connected it to my monitor and other peripherals and everything worked and loaded as expected, it seems to work fine, I’m writing from it.

I came up with such an incomprehensible solution to such a very serious problem. Regarding those dollars all over the screen, a friend says that these are signs of money :), well, I’ll hope. Good luck!

Such problems can easily appear due to problems with the power supply. If you don't have a source uninterruptible power supply, then I recommend installing at least surge protector. You can use Lezard. Their products have recently appeared in big store ETM. Of course, a UPS differs in functionality from surge protectors, but it will still help protect your computer a little.

Error 0X000000A5 and stripes on the screen when booting Windows 7 updated: January 11, 2015 by: admin

Hello.

While many errors and problems on the computer can be tolerated, defects on the screen (the same stripes as in the picture on the left) cannot be tolerated! Not only do they interfere with your view, but they can also damage your eyesight if you work on such an image on the screen for a long time.

Stripes may appear on the screen due to various reasons, but most often they are associated with problems with the video card (many say that artifacts appeared on the video card...).

Artifacts mean any distortion of the image on a PC monitor. Most often, they appear as ripples, color distortion, stripes with squares across the entire area of ​​the monitor. So what to do with them?

Right away I want to make a small disclaimer. Many people confuse artifacts on a video card with dead pixels on the monitor (a clear difference is demonstrated in Fig. 1).

A dead pixel is white dot on the screen, which does not change its color when the picture on the screen changes. Therefore, it is quite easy to detect by filling the screen with different colors one by one.

Artifacts are distortions on the monitor screen that are not related to problems with the monitor itself. It’s just that the video card sends such a distorted signal to it (this happens for many reasons).

There are software artifacts (related to drivers, for example) and hardware artifacts (related to the hardware itself).

Software artifacts

As a rule, they appear when launching some 3D games or applications. If you experience artifacts when loading Windows (also in), most likely you are dealing with hardware artifacts (about them below in the article).

There are a lot of reasons for the appearance of artifacts in the game, but I will analyze the most popular ones.

1) Firstly, I recommend checking video card temperature at work. The thing is that if the temperature reaches critical values- then everything is possible, from distortion of the picture on the screen to failure of the device.

You can read about how to find out the temperature of a video card in my previous article:

If the temperature of the video card exceeds the norm, I recommend cleaning the computer from dust (and paying special attention to the video card when cleaning). Also pay attention to the operation of the coolers; perhaps one of them is not working (or is clogged with dust and does not spin).

Overheating most often occurs in hot summer months. To reduce the temperature of the system unit components, it is even recommended to open the unit cover and place a regular fan opposite it. This primitive method will help to significantly reduce the temperature inside the system unit.

How to clean your computer from dust:

2) The second reason (and quite common) is drivers for video card. I would like to note that neither new nor old drivers provide a guarantee of good performance. Therefore, I recommend updating the driver first, and then (if the picture is just as bad) rolling back the driver or installing an even older one.

Sometimes using “old” drivers is more justified, and for example, they more than once helped me enjoy a game that refused to work normally with new versions of drivers.

How to update drivers with just 1 click:

3) Update DirectX and .NetFrameWork. There is nothing special to comment here, I will give a couple of links to my previous articles:

4) Lack of shader support will almost certainly result in artifacts on the screen ( shaders- these are a kind of scripts for a video card that allow you to implement various special functions. effects in games: dust, ripples on the water, particles of dirt, etc., everything that makes the game so realistic).

Typically, if you try to run new game on old video card- an error is displayed stating that it is not supported. But sometimes this does not happen, and the game runs on a video card that does not support the required shaders (there are also special shader emulators that help run new games on old PCs).

In this case, you just need to carefully study system requirements games, and if your video card is too old (and weak), then, as a rule, you won’t be able to do anything (except overclocking...).

5) At overclocking a video card Artifacts may appear. In this case, reset the frequencies and return everything to initial state. In general, overclocking is a rather complex topic, and if handled inappropriately, you can easily damage the device.

6) A glitchy game can also cause image distortion on the screen. You can usually find out about this by looking at various player communities (forums, blogs, etc.). If similar problem If there is one, you won’t be the only one who will encounter it. Surely, they will also suggest a solution to this problem (if there is one...).

And hardware artifacts

Except software artifacts There may also be hardware problems, the cause of which is poorly functioning hardware. As a rule, you will have to observe them absolutely everywhere you are: in the BIOS, on the desktop, when loading Windows, in games, any 2D and 3D applications, etc. The reason for this, most often, is the detachment of the graphics chip; less often, there are problems with overheating of the memory chips.

For hardware artifacts, you can do the following:

1) Replace chip on video card. Expensive (relative to the cost of the video card), it’s tedious to look for an office that will carry out repairs, it takes a long time to search for the right chip, and other problems. It is still unknown how this repair will be carried out for you...

2) Trying on your own warm up the video card. This topic is quite extensive. But I will say right away that such a repair, even if it helps, will not help for long: the video card will work from a week to six months (sometimes up to a year). You can read about warming up the video card from this author: http://my-mods.net/archives/1387

3) Replacing the video card with a new one. The fastest and simplest option, which sooner or later everyone comes to when artifacts appear...

That's all for me. Good PC work to everyone and fewer errors :)

User question

Hello!

Recently, stripes and ripples began to appear on my computer screen; the picture can sometimes twitch when passing a horizontal stripe.

This happens only in games. I tried reinstalling Windows, changing video drivers - no effect. These are artifacts on the video card (I was told so at the service center), and it needs to be changed. Or are there other options?

Good day!

In general, the presence of any distortion on the screen is a very alarming sign. Stripes and ripples can appear on the screen both due to problems with software and problems with hardware. In this article I will try to analyze the most basic things that you have to deal with, what can be done and taken to diagnose and find the cause (well, knowing the essence of the problem, you can often fix it on your own 😉).

Photo of a monitor with vertical (horizontal) stripes and ripples (as an example to understand what we are talking about)

What to do if ripples and stripes appear on the screen

STEP 1: check if the cable connecting the monitor to the computer is intact

The first thing I want to start with is the cable (perhaps this is somewhat banal, but still!). The fact is that it can be accidentally interrupted, chewed (by a pet, a cat, for example), etc.

And in general, many users do not always screw the VGA cable (for example) so that it does not come off. Often, simply adjusting the plug will solve the problem.

The photo below shows a damaged USB cable (the video cable is also damaged) ...

I'll add a couple more notes (regarding wires):

1. do not use long cables: if the length of your video cable is more than 3 meters, then the image on the screen may begin to distort (here, of course, a lot depends on the monitor);
2. see if the video cable is intertwined with the cable of the printer, telephone charger, cable TV, etc. The fact is that such elements can create interference (especially in the absence of shielding). Try placing the video cable away from other wires.

STEP 2: Pay attention when artifacts appear

Immediately after turning on the computer, i.e. they are there when entering the BIOS (), and when loading the OS, and after it has loaded, in all applications and games;

They appear only at a certain stage: for example, when loading the OS, and then disappear. Either when entering a particular game, or after some time spent in the game.

If in the first case, you can’t work on a PC at all and you need to eliminate the cause (you can ruin your eyesight), then in the second, for example, you can still long time keep working.

By the way, such a simple observation will help determine the cause of the malfunction. For example, if you experience artifacts in only one game, then most likely the problem lies in the temperature, driver, or errors in the game itself.

I will also note that in the second case, the chances of restoring the PC/laptop (without material costs) are much greater!

STEP 3: Connect another monitor for diagnostics

This step is very important!

It will allow us to determine whether the artifact problem is related to a malfunction of the monitor, or to problems in the system unit (video card, motherboard).

Surely in every house where there is a PC, there is a TV, or another screen of some kind ✌. For example, if stripes appear on your laptop screen, connect it to a regular monitor and see if there are any distortions in the picture. Now anyone modern monitor can be easily and quickly connected to a computer using an HDMI cable (sold in almost every computer store).

In the photo below: a TV was connected to the laptop in order to see if there would be artifacts on the TV screen.

If there are no artifacts on the other screen and everything is fine: Then the problem is with the monitor. By the way, on CRT monitors, the problem of the appearance of horizontal stripes. In general, if the monitor itself is to blame for the streaks on the screen, then without having experience in repairing equipment, you cannot do without it.

If artifacts are present on another monitor: then the problem is probably in your computer: the problem is either with the software or with the hardware. We'll figure it out further...

STEP 4: Check the temperature of components (video card, CPU)

If there are stripes on the screen, first of all you need to look at the temperature of the video card. This can be done using special. utilities: .

An example in the screenshot below. Checking the temperature in GPU-Z utility(see the line "GPU Temperature").

In general, it is difficult to give an exact value critical temperature of the video card : here you need to look at your specific model(use your manufacturer's website). But in general, everything above 80 gr. Celsius - should alert you to a thorough check.

Help!

How to find out the acceptable and critical temperature your video card:

If overheating is suspected, it is recommended first clean your computer from dust , replace thermal paste. Dust often blocks ventilation openings, reducing air circulation. As a result, the temperature inside the system unit (laptop) begins to rise.

In laptops, by the way, it is easy to determine overheating if you put your hand near ventilation holes(usually they are on the left): very hot air begins to come out from there, you can even get burned.

By the way, these utilities can measure the temperature during your game, tracking all the maximums and minimums. As soon as you notice the appearance artifacts– check what the temperature was.

Help!

1) Checking the video card for performance, testing for reliability and stability -

2) How to perform a stress test of the processor and the system as a whole, does it maintain frequencies, is there any overheating -

At all, pay special attention to temperature in hot summer months, when PC components often heat up to significant levels. To reduce the temperature in the system unit, simply remove the side cover and place a regular fan opposite.

There is a special one for laptops. stands that help improve air circulation (due to which it is possible to reduce the temperature by 5-10 degrees Celsius).

STEP 5: check and update your video card drivers

Drivers are everything...

Video card drivers can have a significant impact on picture quality (especially for 3D games).

For example, about 15 years ago I had a video card Ati Radeon 8200 (if I'm not mistaken), there were several versions of drivers (official and not).

So, on official drivers, on the most latest version, there was a glitch: some elements in the games (in particular fire) were not shown - instead of them there were some squares, sometimes stripes... When I switched to a different version of the drivers, everything worked as expected. Over time, the developers fixed this bug...

By the way, pay attention to how the computer will work when you remove the drivers: will there be stripes or ripples. Below is a link to an article that will help you remove and update drivers.

STEP 6: a few words about overclocking your video card

If you overclocked your video card, then it is likely that artifacts could appear (especially if you have never done this before and practical experience no 👀).

Overclocking, in essence, is this a whole science, where you need to know and feel quite accurately how the hardware will behave (and, of course, there is always a certain risk).

Try resetting the frequencies and checking functionality. As a rule, if the problem was related to unsuccessful overclocking, it is solved.

The photo below shows an unsuccessfully overclocked Doom 3

In general, in most cases, if software overclocking fails - modern video cards, processors and memory themselves reset to safe settings.

STEP 7: Check if the desired shader version is supported

Each video card supports certain version shaders (and games, by the way, also require a certain version, see the description for any game).

The point is: if you are trying to run a new game on a video card that is not new, it is quite possible that it does not support the necessary pixel shaders.

In general, usually, in this Windows case will inform you that the game cannot be launched, an error will appear. But sometimes this doesn’t happen, and the game starts with distortions in the picture (especially now there are special shader emulators that allow you to run games on video cards that are not approved by the developers).

So if you have a problem in any one game, check : whether your video card model is included in the list of those supported by the game.

STEP 8: what else to pay attention to (hardware malfunction: video card, motherboard)

As a rule, when there are problems with hardware, artifacts appear everywhere: in the BIOS, when loading Windows, in games, in any other programs. In some cases, artifacts appear when the video card is heated to certain temperatures (for example, in games), etc. Most often, the reason lies in the detachment of the graphics chip, or overheating of the memory chips.

You can try the following: open system unit, remove the video card and inspect it. Isn't there any visible damage? Most likely, there will be no visual signs of failure on it (statistics from personal experience).

However, with heavy dust and high temperature indications in AIDA, Speccy, I recommend this:

1) First: clean the system unit from dust (can be blown out with a regular vacuum cleaner). .

2) Pay special attention to the video card contacts. Try cleaning her contacts with regular elastic band (clean the part that is inserted into the motherboard). Then blow through the entrance itself where it is inserted. With artifacts this method helps, but not in all cases.

3) If the artifacts are not missing, it would be a good idea to check the video adapter on another work computer (although I understand that this advice is unlikely to work ordinary users, not everyone has 2 PCs at home...).

The photo below shows what normal capacitors look like (red arrows) and a swollen one (circled).

The motherboard/video card could also fail for reasons beyond your control. (i.e. without overclocking). For example, there was a power outage, a manufacturing defect, overheating, etc.

In general, for problems with iron (and lack of repair experience), it is better to contact the service center.

However, I want to warn you right away:

1. Some craftsmen may offer to repair and replace the chip on the video card. It is expensive (almost like a new video card), and it is unknown how the repair will be carried out, and how the video card will behave later. In general, I do not recommend it;

2. They may suggest warming up the video card (sometimes called hot). This topic is specific and extensive. But I want to say right away that such a refurbished video card (in best case scenario) will not work for long, at most another six months. Then it still comes to an end...

The most preferable option for these problems is to replace the video card with a new one. In the end, it's cheaper for the wallet... 👌

By the way, I want to give a couple of links to do-it-yourself repair video cards:
