CompTIA A+ Core 2 (220-1202)Software TroubleshootingMedium
A client reports that their Windows 11 laptop, which has an SSD, has become very slow to boot and applications often freeze. The technician opens Task Manager and observes that the disk utilization is consistently at 100%, even when no applications are actively running. What is the MOST likely cause of this issue?
- AThe system has insufficient RAM.
- BThe SSD requires defragmentation.
- CA background process is excessively using disk I/O.
- DThe GPU drivers are outdated.
Show answer & explanationAnswer & explanation
Correct answer: C. A background process is excessively using disk I/O.
Consistent 100% disk utilization on an SSD, especially with slow performance and freezing, points to a process constantly accessing the disk. This is a common symptom of a runaway background process or malware.
Why the other options are wrong
- A. Insufficient RAM typically leads to high CPU usage or page file usage, not consistently 100% disk utilization, unless the system is constantly swapping memory to disk.
- B. SSDs do not require defragmentation; doing so can reduce their lifespan. This would not cause 100% disk utilization.
- D. Outdated GPU drivers primarily affect graphical performance or display issues, not disk utilization.
High Disk Utilization Troubleshooting
High disk utilization, often seen as 100% in Task Manager, indicates that the storage device is constantly active, leading to severe system slowdowns and unresponsiveness.
- Common causes include runaway background processes, malware, or failing hardware.
- Troubleshooting involves identifying the process consuming disk resources.
- SSDs should not be defragmented; this is for HDDs.
Memory trick: Identify the hungry process eating your disk.
