The videocard does not work: what to do?
|The videocard is one of the most important components of the modern computer. The videocard is responsible for creation of the image which the user during the work with the computer sees on the monitor. And if the videocard for any reasons breaks, it leads to a paralysis of operation of all computer. |
All breakages of videocards can be classified as program or hardware. Program breakages are the malfunctions in operation of the videocard caused by actions any ON, the wrong installation of drivers, etc.
It is possible to find and correct program malfunctions of the videocard as follows. If mistakes arise during the work any ON, for example, difficult three-dimensional game, it is necessary to remove it ON and to try to establish it repeatedly. It is possible to try to remove completely installed videocard drivers then to establish the new. For example, new drivers can be found on the sites of producers of videocards. Also it is necessary to establish the freshest version of a set of DirectX interfaces. Sometimes mistakes in older versions of drivers also cause problems with the videocard.
If the taken measures do not help, it is possible to try to reinstall an operating system. Thus after the OS installation it is necessary to install first of all motherboard drivers, then – videocard drivers, in the last turn – a set of DirectX interfaces. Posl of it it is necessary to install that application which caused failures in operation of the videocard and again to start it. If failures do not appear any more – the problem is solved.
If the above described actions did not help to fix a problem, most likely, breakage of the videocard has hardware character. Hardware breakages include technical malfunctions of the videocard: the "blown-up" condensers, refusal of work of a cooler, faulty contacts and other.
How to learn, what the videocard broke? As a rule, "symptoms" of breakage of the videocard look so:
About problems with the videocard the special speaker (the sound loudspeaker) of BIOS signals. Depending on the BIOS version, signals can be various. For example, AWARD BIOS gives out 1 long and 2 short sound signal if there is an error of the videocard or connection of the monitor. AMI BIOS at an error of the videocard gives out 8 short sound signals.
PHOENIX BIOS notifies on malfunctions in operation of the videocard as sound signals on the scheme 3-3-4: three signals, pause, three signals, pause, four signals. In this case the system cannot find the videocard. Also signals 3-4-1 and 3-4-2 testify to videocard errors in PHOENIX BIOS.
Its replacement on obviously serviceable, reinstallation of the videocard in other socket can become the solution of hardware problems with the faulty videocard. It is also necessary to make sure that the problem videocard does not overheat that on it the necessary feeding tension moves. Special utilities, such as Everest, RivaTuner will help to find out it.
These utilities allow to trace constantly a condition of the videocard (and not only), to receive data on the current temperature of the adapter, tension. If these parameters are beyond norm is a reason for concern.
It is possible to use similar utilities only in case the computer turns on and the signal on the monitor is given (let and distorted). In other cases it is necessary to check all necessary parameters manually.
Tension can be measured by the special device – the voltmeter or a multimeter. Temperature is taken by means of the thermal sensor. Experienced users to the touch define a videocard overheat: too hot or too quickly heating up surface often testifies to problems.
Happens that not the videocard, but her some "neighbors" is guilty of problems. So, problems with operation of the videocard can be caused by malfunctions of the power unit, motherboard. In more detail about that how to find and solve similar problems – in the subsequent materials of the Country of councils.
