When diagnosing a system experiencing intermittent video artifacts and graphical glitches, which of the following hardware components, beyond the GPU itself, is most likely to be a root cause, assuming the GPU has already been tested and is functioning correctly in a known good system?
The power supply unit (PSU), failing to deliver stable voltage to the PCIe slot.
The CPU's integrated memory controller.
The RAM modules, specifically due to timing mismatches or voltage instability.
The motherboard's Northbridge chipset, responsible for PCIe lane management.
Q2Domain Verified
specifies it's been ruled out. Intermittent video artifacts can arise from unstable or corrupted data being fed to the GPU. RAM issues, such as incorrect timings, voltage fluctuations, or faulty modules, can lead to data corruption that manifests as graphical glitches. The CPU's integrated memory controller (
Degradation of the individual NVMe SSDs due to excessive wear.
A firmware corruption issue within the RAID controller itself.
A faulty CPU, specifically its PCIe lanes, impacting all NVMe communication.
is involved in RAM access, but direct RAM module instability is a more common and direct cause of such artifacts. The Northbridge chipset (C) manages PCIe, but its failure typically results in more severe connectivity issues or system instability rather than nuanced graphical artifacts. A failing PSU (D) can cause a wide range of problems, including instability, but voltage fluctuations specific to the PCIe slot causing *intermittent graphical artifacts* when the GPU itself is known good is less direct than faulty RAM. Question: A user reports that their high-end workstation, equipped with multiple NVMe SSDs in a RAID 0 configuration, experiences sudden, unrecoverable data corruption on all drives simultaneously. The system boots but applications crash frequently. What is the most probable hardware failure contributing to this catastrophic data loss scenario? A) A failing SATA controller on the motherboard.
Q3Domain Verified
You are troubleshooting a server that intermittently fails to POST, displaying no diagnostic codes and exhibiting no fan spin on startup, but occasionally powers on and functions normally for extended periods. After ruling out a faulty power button and a loose power cable, what is the most likely hardware culprit that explains this erratic behavior?
A defective CMOS battery, causing intermittent BIOS corruption.
A defective RAM module, preventing the system from completing the Power-On Self-Test.
A faulty motherboard, specifically a compromised VRM (Voltage Regulator Module) for the CPU or chipset.
A failing CPU, exhibiting unstable power delivery to critical boot components.
