Common industrial machine fault solution of graphics

common industrial machine fault solution of graphics.

a, fault performance:

1, although occasionally boot after normal boot, but no image display industry.

2, occasionally boot screen, enter the desktop disappeared or is normal after launch, using flowers screen after a period of time.

3, frequent intermittent boot after the video card driver is missing, enter the desktop can only display 640 * 480 color pattern, must reinstall video card driver. This kind of failure occurs when the user after the repair most expressed as industrial display flashing, color is not straight or icon.

2, the cause of the problem:

1, mostly bad video card. For the graphics work bad or radiator graphics chips overheating caused damage, bad memory part of the chip damage will produce the fault phenomenon.

2, a few belong to compatibility problems.

3, the individual is caused by the motherboard AGP slot insufficient power supply.

this is primarily a motherboard AGP slot only provide standard electrical current, and power consumption of individual graphics beyond the AGP slot can provide large current value, graphics and does not provide auxiliary power supply interface at the same time, so can produce occasionally boot no display, or is as shown in the working process of the large-scale complex 3 d games when suddenly freezes or black screen.

three, solution:

to just buy the machine if there is a compatibility is bad or the failure of performance, easy to handle, a new can directly. If it is in the use of a few months later there is a problem, but in the test and can't find out, only strongly demanded in the new computer company or change other brand products.

a: common faults on no display

this kind of failure in general because of poor contact or motherboard slot graphics card and mainboard has a problem. If for some integrated graphics motherboard, memory Shared main memory, attention should be given to the location of the memory chips, generally on a memory stick slot should be inserted with memory chips. Because of the graphics card boot no display failure, boot after tend to let out a long two short hum.

common fault 2: color display is not normal, this kind of failure generally has the following several reasons:

1, industrial display their own fault;

2, graphics card damage;

3, display card and industrial display poor contact line;

4, color is not normal in some software runtime, generally found in the old machine, has a check color options in the BIOS, the open;

5, industrial monitors magnetized, can this kind of phenomenon is usually due to magnetic objects too close to be caused by, after magnetization may also cause display appear the phenomenon of deflection.

three common faults: video card driver is missing

video card driver is loaded, run after a period of time lost driver automatically, such failure is due to the poor quality of the graphics card or graphics do not compatible with the mainboard, the graphics card temperature is too high, which can lead to system instability or a crash, only replace the video card.

common fault 4: screen abnormal noise point or design

this kind of failure is usually due to the graphics card memory problems or graphics card and motherboard caused by poor contact. Need to clean graphics gold finger parts or replace the video card.
