A technician is trying to diagnose a laptop that is experiencing heavy artifact corruption and random loss of video during operation. Which of the following are MOST likely causes of this problem?…
The correct answer is A. Integrated system video chip is failing and/or near death. C. Incompatible or untested video drivers have been installed. Artifact corruption and random video loss on a laptop are most commonly caused by a failing hardware video chip or by incompatible drivers that cannot communicate correctly with the display hardware.
Question
A technician is trying to diagnose a laptop that is experiencing heavy artifact corruption and random loss of video during operation. Which of the following are MOST likely causes of this problem? (Select TWO).
Options
- AIntegrated system video chip is failing and/or near death.
- BVideo drivers were not installed directly from Microsoft update.
- CIncompatible or untested video drivers have been installed.
- DThe BIOS is not set for the proper operation temperature of the video chipset.
- EThe BIOS is underclocking the video card's operating speed.

Why each option
Artifact corruption and random video loss on a laptop are most commonly caused by a failing hardware video chip or by incompatible drivers that cannot communicate correctly with the display hardware.
A degrading integrated GPU can produce graphical artifacts, screen tearing, and sudden video dropout as its transistors, memory, or solder connections fail under thermal and electrical stress.
The source of a driver download (Microsoft Update vs. manufacturer website) does not determine compatibility - what matters is whether the driver version matches the hardware, not where it was obtained.
Incompatible or untested video drivers may send incorrect commands to the GPU or fail to properly manage its memory and rendering pipeline, resulting in visual corruption and intermittent display loss.
BIOS does not contain a setting for video chipset operating temperature; thermal management is handled by the OS, drivers, and firmware independently.
BIOS underclocking of the video chip would reduce performance but would not produce artifact corruption or sudden video signal loss.
