Artifacts on the computer cause. Recovery of a video card after overheating. We treat artifacts. What are artifacts

Not every user knows why they appear and how to eliminate video card artifacts.

However, this is a common occurrence, and after all, many characteristics of a computer in terms of the image on the screen depend on the quality of the video card.

Definition

What are artifacts? These are sudden, unconditional and interfering with work, distortion of the image on the monitor. They can appear quickly and quickly disappear, or they can be present for quite a long time.

There are many types:

• The appearance of glare-like highlights on the screen;
• The appearance of, as it were, not loaded areas or vertical, horizontal stripes;
• Chaotic scatter of parts of the image across the screen, etc.

Most often, this phenomenon occurs when using programs and games that have a fairly significant load on this device. These are mainly online games, graphic editors such as Photoshop, some drawing applications, etc. Such distortion can appear both exclusively during the game and for some time after it is turned off.

They appear for the following reason: the video card cannot process the image correctly and in full. As a result, she transmits to the screen its distorted version, filled with such problems. The picture changes and floats.

It is very important to distinguish this phenomenon from dead pixels. Broken pixels on the screen are white or light green areas on the monitor. They are stationary, do not move and are always present when the monitor is turned on, since they are connected directly with it, and not with program characteristics computer.

Causes

As with almost any breakdown, all the causes of its occurrence can be divided into two large groups. The first of them is hardware, that is, connected directly with the device, with "hardware". The second is software, respectively.

Hardware

Such artifacts always appear. That is, they are present both in 2D images, for example, when loading, and in 3D. They do not depend in any way on the load on the card at the moment, and can be present either permanently or periodically disappearing.

A characteristic feature of such problems is that they grow over time, as negative processes in the map develop further. As a result, a breakdown can lead to the fact that the computer will stop loading altogether or will freeze quickly.

In this case, we can say that there is an immediate physical breakdown in the card itself. Some series and brands are subject to such breakdowns to a lesser extent, others to a greater extent.

Another type of hardware problem is changes in the operation of the computer that negatively affect the operation of the card. It may be overheating, a drawback random access memory and other. In this case, artifacts mainly appear in 3D, while in 2D they are absent.

Correction

In most cases, only a service can help in this situation, since special skills are required to eliminate it. For example, chip delamination is a common cause of this failure. To fix it yourself and without special equipment is beyond the power of not only an ordinary user, but also a fairly advanced one.

This problem is characterized by the periodic appearance of artifacts. This is due to the fact that the chip is not always peeled off; sometimes it contacts the board normally. At this point, the distortion disappears.

However, any breakdown, even if it is timely eliminated in the service, shortens the life of the device, in this case, the video card. Therefore, it is easier to replace it in a timely manner, since after repair it will still function normally for no longer than one year.

Software

It is easy to distinguish this type of problem. They occur exclusively in 3D games, or even in any one particular game. This is due to the fact that the load on the video card is very high and it cannot correctly process or transfer to the screen a complex and rapidly updating picture.

Correction

There are several ways to solve this problem. But it's worth starting, in any case, with cooling the system. It is recommended to clean or replace the cooler, as well as replace the thermal grease in the service.

The second step is to reset the settings and frequencies of the problem game to the "default" parameter. Often the problem disappears already at this stage. But in order to play comfortably enough, do the following:

1. Update the memory card drivers by following the path Device Manager - Video adapters - Memory card;

Hello everyone! Today we will discuss what gives rise to, what are the artifacts of a video card and what they look like, as well as how to deal with this phenomenon.

What are artifacts

This is the name of the distortion on the monitor, which appears, it would seem, without apparent reason... They can appear not only in games, but in the browser, on the desktop, and even when booting windows... Artifacts can look differently:

• Alien elements randomly scattered across the screen that do not fit into the overall picture;
• The absence of an image (as if it had not been loaded) along vertical or horizontal stripes;
• Highlights resembling glare.

Sometimes artifacts are confused with dead pixels, but this is not entirely correct. These elements appear on the matrix of the monitor and can be black, green or white. They are stationary and do not disappear, regardless of the operating mode of the computer.

Artifacts can appear suddenly and just as unexpectedly disappear.

What causes artifacts

The reasons for the appearance are divided into two large categories: hardware and software.

It is important to remember that for any of the reasons, their occurrence is due to the incorrect operation of the graphics accelerator.

Hardware artifacts

They can occur both in a 3D game and during the operation of any 2D application. Their appearance does not depend on the load on the video card, but they appear and disappear without visible patterns.
One of the main reasons can be physical damage to the video card, in particular, the delamination of the graphics chip. This does not depend on the brand and model of the video card, and there is always a certain risk, regardless of the device used.

The only acceptable option in this case is to send the device to a service center. However, it should be borne in mind that after the repair, the video card does not work for long - on average, no more than a year. There is a reason to think about replacing it.

The second common reason is overheating of the device in general and the graphics chip in particular. You can test the operating temperature using the Everest utility or AIDA 64. If it is more than 90 degrees, you should take care of cooling the device.

The first thing to do is replace the thermal grease between the graphics card cooler and the graphics chip. To do this, you need to carefully dismantle the device and remove the fan along with the cooler, and then evenly spread 2 mg of thermal paste over the surface of the chip.

Do not forget to periodically clean the cooler and fan from dust - a lot of it accumulates. We recommend cleaning at least once a month, especially if the computer is under a desk and the fans are sucking in air.

And the last reason that should be paid attention to is lack of nutrition. This is observed when upgrading a computer, when the owner installs a powerful graphics accelerator and connects it to the old power supply unit.
In this case, it is recommended to clarify the specification of the power supply unit and the video card - whether enough power is supplied to the graphics accelerator.

Software artifacts

This type of artifact occurs exclusively in 3D applications - usually in games. It so happens that distortions appear in one particular game, and the rest work fine. What can be done in such a situation:

• Update video card drivers. It is best to use a specialized utility - Nvidia Experience or AMD Catalyst Control Center. The program will download the latest drivers suitable for your device.
• Update DirectX.
• Install the latest Net.Framework and Visual C ++ libraries.

Often the reason for the appearance of artifacts is a user error: when installing a new game, he does not install additional visual components that the application uses. Updating all of the above items will usually fix the problem.

Wrong overclocking

The reason may be incorrect overclocking of the video card - if you raise the operating frequencies higher than the recommended ones, as a rule, artifacts appear even on the desktop. When starting a 3D application in this case, it usually glitches for a short time, and then closes with an error, since the graphics driver is being installed.

If you use utilities such as MSI Afterburner or Riva Tuner, overclock the video card gradually: raise the frequencies a little and put the load on the graphics chip.

To do this, you can use the built-in benchmarks or a special furmark program designed for stress testing the device.

As soon as artifacts appear during rendering, stop increasing the operating frequencies. Reduce them back to the point where no image distortion occurs.

Ripples, flashing stripes, image distortion on the display screen of a PC or laptop, it is customary to call artifacts. The appearance of artifacts can indicate malfunctions of various devices in the computer system. What devices are these, what exactly is the cause of the problem and how to get out of this situation? When artifacts appear on the PC screen, first of all, you need to check the cable connecting the system unit and the monitor - are the connectors tightly inserted into the ports, are they fixed VGA - or DVI -connectors with screws.

1. Connection cable

If everything is in order with this, then the cable itself is checked to see if there are any kinks on it. But cable damage may not always be visible. In any case, the PC and the monitor must be connected using a different cable, if not with the same connection interface, then at least with an alternative one. Modern discrete graphics cards generally support all three types of interface - DVI , VGA and HDMI, and modern monitors - at least the last two.

For artifacts to appear on the screen, it is not necessary that VGA- the cable has been damaged, problems may arise simply due to its poor quality. When replacing the latter with a budget flimsy cable with blue connectors, you should prefer a thick cable with ferrite rings and black connectors. If both the video card and the monitor support more modern interfaces DVI and HDMI, it is advisable to connect through them.

2. Ports on the video card

Port issues may cause artifacts to appear on the screen VGA , DVI and HDMI on the sistemnik's video card. If the roots of the situation do not go deeper, in the malfunctions of the GPU itself, and the video ports are simply covered with a layer of dust from the inside, the malfunction can be eliminated by cleaning the PC case.

3. Monitor

Various image distortions may indicate a malfunction of the monitor. Whether the cause of the problem lies in the monitor, it is easy to check by connecting it to another device - a PC, laptop, tablet or even a smartphone.

The above situations are only for PC assemblies, with laptops in this regard, it is more difficult. In order to diagnose a malfunction of the display, its connection loop, it is better to immediately contact the service center. On your own in a laptop, you can only check some of the nuances associated with the video card - whether the distortions on the display indicate its overheating or about a crookedly installed video driver.

4. Video card

A crookedly installed video driver can only in rare cases cause artifacts. It's easy to check this moment: just enter BIOS devices and analyze the picture quality. If suddenly such a rare cause of the problem is confirmed, you will need to reinstall the video driver in the Windows environment.

Much more often, artifacts on the screen appear in case of overheating of the video card - if its temperature exceeds the maximum allowable limit in 80 °... The temperature of computer components, in particular, its graphics devices is measured using programs GPU-Z , HWmonitor , Speccy , AIDA64 and their analogues.

You can solve the problem with overheating by cleaning the dust inside the PC or laptop case. If this does not help, you need to contact the service center. Here you will need to either install additional cooling, or troubleshoot the video card, or change it.

Whether the cause of the problem lies in the video card is easy to check by switching your PC or laptop to an alternative graphics, usually built-in. If artifacts appear on the screen just when the built-in graphics are active, forecasts for such cases, alas, are disappointing. You may need to change the processor or motherboard.

There may be several reasons for the appearance of artifacts on the monitor screen. This is a malfunction in the monitor, a broken VGA, DVI, HDMI cable or incorrect video card firmware. There could also be a dumping of the graphics chip or memory chips.

Types of faults - we find and fix the problem

First, we determine the cause of the malfunction, then, if it seems possible, we try to eliminate it. For example, if artifacts appeared on the monitor immediately after overclocking or flashing the BIOS of a video card, then we are looking for the reason in this direction.

If you dropped the power supply from the monitor, and did not let it dry thoroughly, inadvertently rearranged it, then the problem probably lies inside the monik, or a bad cable connection.

Finding a malfunction in the video card

If the video card was unsuccessfully flashed with the wrong BIOS, then artifacts usually appear on the monitor. They can either completely cover the screen or partially. To eliminate them, you need to understand what happened before the appearance of image distortion on the screen.

How to check a video card for artifacts

With excessive overclocking, graphic distortions begin to appear only after loading the operating room. Windows systems or launch 3D applications. And if artifacts appear when loading BIOS (when starting the computer). Then: either it is an incorrectly wired BIOS of a video card, or a blade of a graphics chip or memory chips.

In the event of a GPU dump, it is more profitable to look for another video adapter than to have it repaired at a service center. Below there is a video that will show, using an example, how to solder memory microcircuits with a soldering hairdryer and get rid of artifacts on a video card.

As you can see, artifacts can be of different types in case of problems with the graphics accelerator. However, graphics chip overheating is often to blame. This happens if it has not been done for a long time. So, we proceed to the methods of solving this problem, from the simplest to the most complex.

Frequent video card malfunctions

First reason: wrong overclocking

First you need to know exactly the model and brand of the video card. The box usually contains its basic characteristics: brand, model name and other information.

You can also run the GPU-Z program, it will show everything. Unless, of course, the BIOS of a video card from another model was previously flashed. Then find out the standard operating frequencies of your video card through this program. You can also enter the name of your graphics accelerator in the search engine.

Did you find out what kind of vidyuha you have and at what frequencies should it work? If so, very good. Now you need to use a standard overclocking program from MSI, GIGABYTE, ASUS, PALIT or another company. Each company has its own software, download only for your video card and from the official site.

Next, we launch the overclocking program on behalf of the Administrator, and return to the standard values ​​of memory, GPU and shader frequencies. If, when you turn on the computer, you see that the screen on the monitor is black or artifacts remain, you can try to reflash the video card.

The second reason: unsuccessful video card firmware

There is a more complex problem here, but if the artifacts make it possible to make out what is happening on the monitor screen, then it does not matter. It will require a backup.rom made in advance. If it is not there, then you need to disassemble the video card and look at the data of the graphics chip, labels (if not ripped off) and the names of the memory chips.

Then you need to download the BIOS file on the manufacturer's website, but it is important to determine which BIOS from your particular video adapter model. Then the utility Nvflash (NVIDIA) or Amdflah (AMD \ ATI). But when nothing can be disassembled through artifacts, a graphics card built into the motherboard is required. Identified by the presence of a DVI, HDMI, or VGA output on the rear panel.

Let's now take a look at how else you can treat video card artifacts with BIOS firmware. Well, for example, you can use another video card, but if there is an additional PCI-Ex16 slot in the motherboard. And if there is no slot, then you will have to purchase a USB 3.0 riser.

Tip: Before reaching into the computer with your hands, unplug the PC power cord and remove static from your fingers. To do this, touch an unpainted metal surface such as the inside of a PC case.

The third reason: the blade of the graphics chip

Also, artifacts on the monitor screen may appear due to the dump of the GPU or memory. This is a fairly common problem, especially with video cards with a closed chip (closed by a lid like on a central processor).

The blade of the GPU or video memory is determined by screen distortions and multi-colored pixels that are visible from the BIOS and at system startup. Let's see what the artifacts look like on a video card with a dump of a graphics chip or memory chips.

Also after entering Windows computer can completely "freeze" on a black screen. Or after rebooting, the monitor may not be able to determine the working resolution, a Windows startup error (BSOD) will appear.

Tip: sometimes, if you take out a vidyuha with a dump of memory chips or a GPU chip from the PCI-E 16 slot, and then insert it back, the artifacts may disappear for a short time.

How to fix this ailment of the graphics accelerator

If the graphics chip or memory chips are dumped, the video card can be "warmed up", but it is unlikely that a soldering hair dryer, flux and a special oven for supplying uniform heating from below are lying around in your house. Let's watch the video below and find out how you can remove video card artifacts or a black bar from the monitor screen.

Video of warming up memory chips near a video card

There are citizens who like to "bake" their video card in the oven or "iron" it, but this is ineffective. Most likely, the video card will be completely "fried" and will be out of order forever. Therefore, either we buy a new video adapter, or we look and choose the most suitable one on Aliexpress.

Or, as an option, we carry the graphics accelerator to the service center. If the problem is with memory chips, then they can be easily and relatively inexpensively restored by masters on professional equipment.

But if the GPU dump is to blame, then video card reballing is required. However, this is an expensive and complex procedure that helps to remove artifacts from an Nvidia or AMD video card, but it requires both tangible financial costs and high qualifications of the wizard.

Broken monitor cable

The first option: we change the cable, but you also need a VGA, HDMI or DVI cable. We replace it and check, if the problem persists, then go back above and read about how to test a video card for artifacts. You can also try changing the connection to the DVI or HDMI connector.

Second option: you can try to connect the monitor via the integrated graphics core (GPU). To begin with, we make sure of its presence (there is an output for connecting a monitor on the back of the system unit). So, turn off the computer and remove the case cover. Then we take out the battery for 1 minute (reset BIOS) or press the CLR CMOS button (sometimes the RESET button).

It may be necessary to switch the monitor to the appropriate mode (VGA, HDMI or DVI) if it is not determined by itself. If, after switching on, horizontal and vertical stripes or other artifacts appear on the monitor screen, then only the monitor will be the culprit of "this celebration".

We find a malfunction in the monitor

Usually, Monik has problems only after it is washed or dropped, and also from old age and too frequent use (it is always on). When working around the clock, especially on hot days, bad things sometimes begin to happen to him.

The screen image will start to fade or flicker unnecessarily. Then we see that the image on the monitor has disappeared and a black screen has appeared, which from time to time may start showing again. Our culprits are probably the capacitors of the power supply or the matrix cable, let's try to figure it out.

When streaking, dead pixels and artifacts appear

If recently, you accidentally hit the monitor, and after that it stopped turning on or artifacts appeared on the monitor screen. Then you need to look for the reason within it. The fault may be the matrix loop, rarely - artifacts, often - horizontal and vertical stripes.

If the loop is faulty, it is very difficult to repair it yourself; you will need qualified assistance service center... If you notice broken pixels, which are almost invisible and look like a small dot. You don't need to do anything with them. This is a common speck of dust caught on the projection film, or a factory defect. Usually there are up to five such points! It happens, and I have one. =) But if there are more and more of them, then take the monitor to the workshop until the whole screen is jammed ... covered!

We find a malfunction of the power supply

Power supplies can be internal (located inside the monitor) and external. With a faulty power supply, we usually observe a black screen or it is very dim. The appearance of frequent, visible to the eye flickering due to low supply voltage, or its absence (probably, the capacitors along the supply line have swollen). You need to drop them out and replace them with new ones, by the way, on ALIEXPRESSE, you can buy them cheaply.

Tip: when the power supply is located inside the case, you will need to open the monitor. If you are doing this for the first time, I strongly recommend contacting the service center.

To open up the monitor, disconnect all wires. Place the screen face down on a flat surface, preferably on a soft towel or wrinkle wrap. Then unscrew all screws and remove the stand.

Open the case carefully, do not damage anything and do not scratch the screen. It is better to pry the monique with a special lock, or you will have to walk along the sides with the edge of a flat screwdriver.

Now you need to carefully separate the parts of the case and disconnect all the wiring. The main thing is to remember how they were connected (it is better to take a picture). Removing the power supply board - this is usually the largest board on older monitors. Then we inspect the capacitors for swelling (a magnifying glass to help) and replace the unusable ones.

For external power supplies, the repair procedure is similar. First you need to disassemble the block, sometimes it is set on thermal glue (liquid nails) and you have to tinker with it to open it. Then we find the swollen capacitors and solder them off with a soldering iron generously seasoned with rosin or liquid flux.

When replacing burnt Conder, know. You will need to replace them with exactly the same ones, for example, the capacitor rating is 1000uf 25v, which means its capacity is 1000 microfarads, and the maximum operating voltage is 25 volts. And yet, one side of an electrolytic capacitor is always marked with a white stripe and means - minus.

Not every user knows why they appear and how to eliminate video card artifacts.

However, this is a common occurrence, and many characteristics of a computer in terms of the image on the screen depend on the quality of work.

What are artifacts? These are sudden, unconditioned and interfering with work,.

They can appear quickly and quickly disappear, or they can be present for quite a long time.

The second is software, respectively.

This is due to the fact that it is very high and it cannot correctly process or transfer to the screen a complex and rapidly updating picture.

Correction

The second step is to reset the settings and frequencies of the problem game to the "default" parameter. Often the problem disappears already at this stage.

But in order to play comfortably enough, do the following:

1. Update your memory card drivers following the path Device Manager- Video adapters - Memory card;

1. Please update, especially if bugs occur in a specific game;

1. using its driver, manufacturer's utility or special utility;
2. Gradually increase the frequencies and test the game (with the help of such a process it will become clear at what maximum frequency you can play without problems, especially it depends on the GPU parameter);
3. As soon as the maximum allowable frequency of comfortable operation is found, restart the computer.

However, if you have an old video card with low memory installed on your PC, then it will be impossible to troubleshoot in any case.
