An indicator of graphic or video card trouble is a system crash or your laptop/ computer randomly reboots or will freeze when attempting to play a HD movie a 3D game. This can indicate a failed graphics processing unit GPU or IGP, as a worst case.
On Windows 7 or Windows Vista, your computer may indicate a GPU failure by repeatedly reverting back to the Basic interface, instead of using Aero. A stuttering frame rate in a game could mean a graphics card that is having heat issues. You can differentiate from slow performance, because it happens intermittently. Heat problems are almost always caused by a bad video card but sometimes other components such as a CPU. This is definitely fixable however, if left unchecked, it usually ends with complete graphics card failure.
Other sign of bad graphics card can be very low frame rates. The system video card may still function, but a part of it is starting to fail. This is common on modern programmable GPUs, because they have multiple rendering units. Even if some of them fail, the card can still function, just at reduced performance. It is also indicative of bad memory on the card.
Another possible symptom of graphics card failure. Visual artifacts can be of any number of problems, and not all of them are hardware problems. Bugs in a game or in the video card driver software can cause visual artifacts without being indicative of a hardware failure. However, this symptom combined with any of the the above symptoms is a strong sign that a hardware failure is happening.
Signs of a dying video card is overheating; over time, hardware stops running as efficiently as it once did. Ensure proper airflow by cleaning dust and other buildup from the laptop's interior. If the card is still running very hot (and you're not overclocking), it may be reaching the end of its life.
If your system randomly freezes or crashes during operation, especially when performing video-intensive tasks it may be the fault of the video card. If you get a blue screen of death (BSoD), the driver at fault is commonly listed; if it's the video driver, it may indicate a dying card.
If games or movies that performed fine in the past now run sluggishly or not at all, your video card may be dying.
The most obvious sign of a video card being dead or dying is the video not working at all. When you boot your computer and see nothing on the screen, or if your operating system can no longer detect your specific video card may indeed be dying.
