Why there are problems with the video card

Although all manufacturers of computer components tend to make their products as reliable as possible in order to gain a foothold in the market in the conditions of fierce competition, this is not always possible in full. The cause of intermittent faults can be internal defects of microcircuits, poor-quality element base, shortcomings of logic circuits, etc.

Perhaps, every computer owner knows the problems with the video card. If you analyze the percentage of calls to the service centers, it becomes obvious that this type of malfunction is almost a third. The problem with the video card can manifest itself in completely different ways. For example, an error in the operation of the GPU leads to the impossibility of running 3D applications, and the damage of memory cells to the bands on the screen. Of course, to accurately determine the cause of the problem with the video card should be considered comprehensively.

Alas, the owners of laptops are also in a "risk group". Problems with the video card of the laptop are found as often as in full-fledged personal computers. In addition, laptops add a negative additional factor - the effect of high temperature.

The malfunction arises as follows (one of the frequent cases). After the next turn on the computer, on the screen, in addition to the usual picture, strips or dots are displayed. They are present both in the BIOS windows, so in the operating system - everywhere. Look at the photo - on it we provide an explanatory screenshot.

Problems with the video card - this is not a reason for panic. Sometimes the cause of their occurrence is banal. So, if foreign strips are displayed on the screen, you should turn off the computer power, open the computer system cover and find the video card. This is a large board in which the wire from the monitor is connected. It is necessary to carefully inspect the corresponding connector of the motherboard and sliding contacts of the video adapter. If the video card is loosely fixed in the connector, which is typical for a boltless connection (in some cases), then it is enough to move the case slightly enough that the hard wire "monitor-video" partially pulls the card out of the connector, violating the electrical contact. We return the card to the place and fix it. Usually, the working capacity is restored.

Also, problems with the video card may occur due to insufficient cooling

Performance graphics processor. In this case, the bands appear after a while. It is required to remove the cooling system of the video adapter, clean it and replace the thermal paste.

The reason for the abnormal work can be the blade of the chip (low-quality BGA-soldering). Especially this "made famous" some video cards produced by NVidia. It is worth mentioning the infamous 9600GT. In this case, the so-called roasting can restore the working capacity.

In addition, a low-power power supply that does not produce the required current can also lead to strips on the screen. It is useful to carefully inspect the electronic elements that are soldered on the video card. An inflated condenser may very well lead to malfunctions.
