Methods for verifying the video card for operability (part 1)

When mastering a computer, many users do not have problems with the equipment. But if the picture deteriorated over time, artifacts appeared, it is possible that the video card should be checked for operability. How you can do this, you can learn from our article.

Signs of poor performance

Before you sin on the video device, you should make sure that it is in it. It happens that everything indicates a malfunction of the graphics processor, and it was in the transmitted SATA cable. Therefore, we will deal with the main signs of malfunctions, which may indicate damage to the video card, resulting in a drop in performance:

Image on the monitor.

Artifacts are various defects: noise, lines, twitching of the screen. If this happens in the process of working on a computer, it is most likely the case in the video card. The first step is to check the device for operability, but not the fact that it will be possible to do it yourself. Sometimes, the problem can lie so deep that it can not be detected even in the service center (SC). Unfortunately, such cases are not uncommon.

Sound.

Computer hanging can be caused by almost any of its components, however, if the sound loops, this is a plus for the solution, but a minus for the video device. The fact is that if sound defects continue to be heard from the speakers / headphones, then the video card is working poorly and does not cope with its tasks in graphic display.

Any other signs.

All kinds of errors, computer hang-ups and other problems can be associated with any computer component. However, the video card is a device that is always in operation, hence, the probability of its failure is statistically higher. That directly affects the quality of the device.

Remember: when it comes to the computer, everything is relative. Even if the performance of the video card is not ideal, there are problems, this does not guarantee that its replacement will correct the general malfunction. It is not uncommon for a broken processor in a computer to last another year and even two, and the key difficulty was created by an old cooler.
If there are substantial grounds to suspect a video card of a failure, it is necessary to check it for errors and breakdowns.

Viewing a video card

The first step is to inspect the device. It is possible that you will find some malfunctions on the physical level without going into the software one. Pay attention to:

Swell condensers.

Condensers carry the functions of smoothing the electrical voltage. They absorb the charge when the energy jumps and release it during periods of idle time, when there is not enough energy. That is, they constantly overtake a certain tension through themselves. Their malfunction is only the tip of the iceberg of the reasons why the graphics card can work worse.

We are not in vain digressed into physical malfunctions, since they directly affect the performance of the graphics processor. Even one threaded device can seriously reduce the performance of the video card due to its malfunction.
If the apartment is badly wired or the electricity is often turned off / on, and there are energy jumps, check the capacitors for swelling:

Condensers for swelling
These are standard capacitors. Most often they are located on the motherboard, in the same place and come into disrepair (the motherboard interacts most with voltage, since it feeds all other devices).

But on video cards they are also present and can be called tantalum. A slightly different shape, but a bloat in the event of a breakdown will be obvious.
Another thing is solid-state and fully enclosed capacitors. Outwardly they are indistinguishable, but inside – who knows? To verify the functionality, you can use the device with a multimeter or take the video card to a service center. You should ask to check the devices for leakage or swelling.

Be aware that a comprehensive test of a video card will fly into a pretty penny, or entail a laziness of the masters: rarely will anyone want to check every millimeter of the device. Therefore, you need to contact the trusted SC with a good reputation.
Scratches.

When they are detected on the surface of the device, you must also refer the video card for verification. If an important component is damaged, it will affect its performance, and the reason may be hidden in these same scratches.

Other breakages.

There is no point in further testing the performance of the video card, if it is found cracked, cracked, etc. First you need to eliminate physical damage, but it will be much more expensive than just buying a new device.

All the actions considered must be done in order to analyze the video card. This is the first stage of verification. If there is no damage, then the device will work well (at the physical level).
