Errors that occur due to video cards are known as visual artifacts. Most of the time, such artifacts are caused due to some hardware or software problem. So, one should keep updating their system hardware after certain period of time in order to avoid video card related problems.
Make sure that all the fans are working and especially the fan above video card is effective as overheating of video card may be the very first reason of such fault. Rise and fall of the temperature of video card depends upon the kind of program you are running. Running 2D program will keep the temperature of video card cool while running 3D program will definitely raise its temperature.There is one silicon chip present on the video card that runs slow due to increase in temperature. You can check this problem by using your system with CPU cabinet open and if by doing so artifacts go away, it means overheating of video card was the main reason. In order to lower the temperature of video card, you can under lock the video card. This will reduce clock rates of video card resulting in lowering the temperature.
Problem in video card can occur due to three sources. First is the Video RAM present in the video card, second is GPU which is a chip on the video and the last one is bus interface whose main work is to transfer data between video card and motherboard.If you want to play high graphics game on your computer, you have to start upgrading the system by upgrading the video card. There are some issues that may come while installing video card. It may happen that you find difficulty in replacing built-in video card with PCI express video card. In such case, check out the manufacturer details whether it is allowing replacement of original video card or not. You can also disable on-board video card from BIOS. Also check whether your motherboard has a jumper or not. Jumper helps in switching between built in and add-on video cards.
One may find difficulty in changing colour depth and resolution of video card. Solution for this problem is quite simple. You have to check whether your video card is being identified in Windows or not. If it is identified then you can update your video card from the manufacturer’s website. Sometime it may happen that your display works only in DOS or at booting time but not in windows. Such problem occurs only when your video drivers are either corrupted or expired. To fix this issue, enter into safe mode by pressing F8 and install proper driver. Overclocking video card may increase the speed of video card. To fix this issue, go in Safe Mode and use tools to restore the normal default speed of video card. If you are unable to change OpenGL or Direct 3D settings of video card then try to install video card vendor drivers as they comes with 3D and other advance options that will improve the video quality for sure.
Most of the computer operation requires video card in some proportion and any kind of problem will affect your computer system directly. So it’s better to troubleshoot video card related problem as soon as possible.
