Failures Most Common on Video Card

A video card, also called graphics card (among other names) is responsible for the processing of the data coming from the main processor (CPU or UCP) and convert them into information that can be represented in devices such as monitors and TVs. It is worth mentioning that this component can have a wide variety of architectures, although they are commonly called in the same way, even if it speaks of a chip video integrated on a plate mother (motherboard) in the latter case, it is more correct to say GPU (graphic processing unit)

Since its inception, the graphics cards have included various features and functions, such as the ability to tune the TV or capture video from an external device. It is important to note that it is not a component found exclusively in current computers, but they have been around for more than four decades and today also are an indispensable part of the gaming consoles, laptops and the home. Its creation dates back to the end of the Decade of 60, time in which the use of a printer is left behind to visualize the activity of computers and began to use monitors. At first, the resolutions were negligible in comparison to the already well-known by all high definition; t was thanks to the work of research and development of Motorola chips features became more complex and its products gave rise to it uses the name of video cards.

Frequent

Confuse the GPU with the graphics card. Although very important, not all GPUS 

and graphics adapters will be on card or are the sole determinant of its quality and

 performance. I.e. the GPU if determine the maximum performance of 
the card, but its performance can be castrated by having other elements that are not at their height, for example a small bandwidth.

Consider the term as proprietary PC video card and compatible. These cards are used on nonPC computers and even without Intel or AMD 

processor and their chips in video game consoles. Confused to the manufacturer of the GPU with the brand of the card. Currently the largest manufacturers of chip graphic PC on the market are NVIDIA and AMD (formerly ATi Tecnologies). This is because you are only, responsible of designing the chip(GPU) graphics. Then, companies such as TSMC and Global Fundities manufacturedthe GPU and later are assembled in PCBs with memories by ASUS, POV, XFX, Gigabyte, Sapphire and other assemblers for sale to the public.

Leaving the circle of PCs, for other devices such as Smartphones, most of the GPU are integrated in "System on Chip" along with the processor and the memory controller.

Check the video card.

• Strip - UPS connected and powered on.

• Leads that are connected, exchanging AC (power) cable with the monitor CPU (to rule out that this damaged).

• Test the source, make it light without which is connected to the motherboard andverify voltages, or connect this source in another PC.

• If it is presumed that the BIOS has been manipulated erase all settings with the "Clear CMOS" jumper.

• Manually connect the "Power Switch", the power switch pins could be physically 

defective.

• Remove all less processor, memory, video and source. If the machine comes on one of the devices disconnected is causing problems. Connect one on one and 

try.

• Exchange: memory, processor and card mother with another PC, the fault will be

 located in any of the previous three.

There is no video:

Check the most obvious monitor.

• Check your connection, strip - UPS connected and powered on.

• The majority of monitors has a led that lights up even when not is connected to the PC.

• Adjustments brightness - contrast.

• When connecting the monitor can be folded some DB15-PIN.

• Try another monitor.

• Use card of POST Diagnostics if available.

• If it is presumed that the BIOS has been manipulated erase all settings with the "Clear CMOS" jumper.
