Signs of a Bad Video or Graphics Card
Pixellation
One of the first indications that you may have a bad graphics card is pixellation. This is a term referring to a screen that looks like it has a very low resolution-the pixels are so large that you can see each individual one on the screen. If your screen was previously displaying at a high resolution and suddenly looks pixelated, even when you check your display settings, that could mean that your video or graphics card is on the fritz.
Lines
If you notice any lines running horizontally or vertically through your screen display, that could be a sign of a bad graphics card. The lines appear either in the same or different places each time you load up your computer. These lines could be the first indication that your graphics card is melting down and will need replacement soon.
3D Images Look One Dimensional
If you know that one of your images is supposed to be in 3D, but it looks one dimensional (flat) or distorted, then you may have a problem with a bad graphics card. The graphics card holds the elements of 3D images together to form the effect of an item that's "popping" off the screen. If the graphics card is not sending commands to combine those elements properly it could be malfunctioning.
Images Blurred
Another way that you can determine that you have a bad graphics card is if the images and text on the screen look blurred and almost indiscernible. A good video or graphics card shows a crisp, clear image-all of the objects have clearly defined boundaries.
