A graphics designer reports that while executing GPU-intensive 3D rendering tasks, their desktop workstation monitor exhibits random colored pixels scattered across the screen (digital artifacts) and screen tearing. During peak rendering loads, the display signal suddenly cuts out completely, putting the monitor into power-saving mode while the host PC remains powered on and operational. Which of the following are the MOST likely root causes for these combined symptoms? (Select TWO.)
- Overheating GPU VRAM or defective video memory chips failing under high graphics processing loadsCevap
- Insufficient power supply unit (PSU) wattage or failing +12V PCIe power delivery during peak GPU drawCevap
- CA damaged fluorescent backlight inverter board within the external high-resolution display panel
- DCorrupted monitor firmware drivers causing physical video signal attenuation over the DisplayPort cable
Cevap
The most likely root causes are overheating or failing GPU VRAM modules and an inadequate or failing power supply unit (+12V PCIe rail) under peak processing load.
Visual artifacts such as random colored pixels, checkerboard patterns, or screen tearing during intensive 3D rendering indicate overheating or failing VRAM on the graphics adapter. Meanwhile, a sudden loss of display signal putting the monitor into power-saving mode specifically when GPU rendering load spikes indicates that the power supply unit (PSU) cannot deliver sufficient wattage or stable +12V power to the graphics card, causing the card to trip its safety shutoff.
