While all manufacturers of computer accessories committed to making its products the most reliable that in the fierce competition to gain a foothold in the market in full is not always possible.The cause of recurrent faults can be internal defects chips of poor quality electronic components, logic flaws and so forth.
Perhaps every computer owner aware of the problems with the video card.If we analyze the percentage of calls to service centers, it becomes obvious that such failure constitute almost a third.The problem with the video card can be manifested in very different ways.For example, an error in the GPU makes it impossible to start the three-dimensional applications, and damage of memory cells - to the fringes on the screen.Of course, to determine the exact cause of the problem with the video card should be considered comprehensively.
Alas, owners of portable computers are also in the "risk group".Problems with the graphics card laptop meet as often as in the full-fledged PCs.In addition, laptops adds an additional negative factor - exposure to high temperatures.
fault occurs in the following way (one of the most frequent cases).After the next turn on the computer screen pictures are displayed in addition to the usual foreign bands or points.They are present in the BIOS windows, so the operating system - everywhere.Look at the picture - it we give explanatory screen shot.
problems with the card - that's no reason to panic.Sometimes the cause of their occurrence is commonplace.So, if the screen displays the foreign bands, then power off the computer, open the system unit, and find the card.It is a large board, which is connected by a wire screen.It is necessary to carefully examine the appropriate connector of the motherboard and graphics card sliding contacts.If the video card is fixed tightly in the slot, which is typical for bezboltovogo connection (in some cases), it is sufficient to move the body a little accident to hard wire "video monitor" partially pulled a card out of the slot, breaking electrical contact.Return the card in place and fix it.Typically, performance is restored.
also problems with the video card can occur due to insufficient cooling
GPU performance.In this case, bands appear after some time.Cooling system is required to remove the video adapter, clean it and replace the thermal paste.
reason for abnormal operation may be a heap of chip (poor quality BGA-soldering).Especially these "famous" some video production NVidia.It is worth mentioning the infamous 9600GT.Recover in this case may be the so-called prozharka.
In addition, a low-power power supply, do not issue the necessary current can also cause lines on the screen.It is useful to carefully inspect elktronnye components soldered on the video card.Swollen capacitor may cause a malfunction.
