Troubleshooting Log
Real-world troubleshooting tickets documenting my hands-on
problem-solving process. Each entry follows a systematic approach:
gather information, reproduce issue, test solutions, document outcome.
Micro SD Card "Need Formatting" - Hardware Damage
Problem: Micro SD card displays a "Need formatting"
error and fails to mount.
Environment: Windows 11, SanDisk 64GB Micro SD,
INSIGNIA USB adapter.
Steps Taken: 8 troubleshooting actions (Verified
connectivity across multiple workstations and adapters, cleaned
physical contacts, updated drivers, and checked status in Device
Manager).
Root Cause: Physical damage to the contact pins
caused by removing the card with tweezers after incorrect insertion.

Old TV Display "Cut Off" (Overscan Issue)
Problem: Desktop edges, corners, and taskbar are
cut off when connected to an older office TV.
Environment: Windows Workstation, 2015 LED TV,
HDMI/DisplayPort
Steps Taken: 10 troubleshooting actions (Verified
cable/adapter integrity, performed hard reset on display, tested
multiple Windows resolutions and scaling percentages, and performed
manual aspect ratio calibration via GPU software).
Root Cause: Overscan: hardware limitation where the
legacy TV display does not automatically sync with modern OS
scaling.
✓ Outcome: Resolved - Applied custom scaling (92%
Horizontal/Vertical) via Intel Graphics Command Center to fit the
display area.

Peripheral Disconnection & System Overheating
Problem: External keyboard and mouse disconnect
during heavy workloads; system exhibits sluggish performance and
excessive fan noise.
Environment: Dell Latitude 5410, Windows, Logitech
K120/M100.
Steps Taken: 12 troubleshooting actions (Verified
battery health via BIOS and powercfg reports, isolated faulty power
supply, conducted full hardware teardown, cleared significant
internal dust buildup, and reapplied Arctic MX-6 thermal paste).
Root Cause: Simultaneous failure of the AC adapter
and thermal throttling due to dust buildup; the power draw from the
maxed-out fan triggered "USB Selective Suspend," shutting off
peripherals to save energy.
✓ Outcome: Resolved - Issued a replacement AC adapter, performed an
internal deep clean, and reapplied high-performance thermal paste to
restore system stability and cooling.

Outlook Search Indexing Failure
Problem: Outlook search returns "No results found"
for all recent emails (current and previous week), despite emails
being visible when scrolling.
Environment: Windows (Accessed via Remote
Desktop).
Steps Taken: 4 troubleshooting actions (Confirmed
email availability via manual scroll, inspected Indexing Options
status, and initiated a manual index rebuild).
Root Cause: The Windows Search Index stalled with
over 7,400 items pending, preventing recent data from being

Microsoft Teams Microphone Failure (Input Device Conflict)
Problem: User's voice is not transmitted during
Microsoft Teams calls despite the microphone not being muted.
Environment: Windows Laptop, Microsoft Teams,
Bluetooth Headset.
Steps Taken: 3 troubleshooting actions (Reproduced
issue via remote test call, verified hardware mute status, and
inspected Windows Sound input configurations).
Root Cause: The system was defaulting to a
connected Bluetooth headset for audio input instead of the internal
laptop microphone.
✓ Outcome: Resolved - Manually switched the input device to the
internal microphone and configured it as the permanent default
device in Windows Sound settings.

Microsoft Word Frequent Crashes (Add-in Conflict)
Problem: Application freezes and displays
"Microsoft Word is not responding" after approximately 10 minutes of
use.
Environment: Microsoft Word.
Steps Taken: 5 troubleshooting actions (Verified
application instability, performed system reboot, isolated and
disabled conflicting COM and Word Add-ins, and verified stability
post-reconfiguration).
Root Cause: Conflicting third-party Add-ins causing
application instability and resource freezing.
✓ Outcome: Resolved - Disabled all third-party Add-ins; Word
application is now stable.

[URGENT] CSV Files Opening in Notepad Instead of Excel
Problem: User's monthly sales reports are opening
as raw text in Notepad instead of organized spreadsheets in
Excel.
Environment: Windows, Microsoft Excel, .csv file
format.
Steps Taken: 5 troubleshooting actions (Provided
immediate workaround via "Open With" context menu, identified
incorrect file association, navigated to Windows Default App
settings, and reconfigured .csv extension to prioritize Excel).
Root Cause: Incorrect "File Association" where
Windows was defaulting to Notepad for comma-separated values (.csv)
files.
✓ Outcome: Resolved - Restored Excel as the default application for
.csv files; verified automatic opening functionality.

Problem: Websites fail to load or experience
significant latency; issue is intermittent.
Environment: Windows Workstation.
Steps Taken: 6 troubleshooting actions (Verified
real-time bandwidth in Task Manager, conducted network route testing
via tracert to verify hop latency, cleared browser cache, and
performed a DNS flush).
Root Cause: Likely intermittent network congestion
or a background system update; connection verified as stable and
performing at optimal speeds during technical audit.
✓ Outcome: Resolved - Performed system optimization and verified
network stability.

Sudden System Shutdown & Data Loss Recovery
Problem: Laptop powered off abruptly during a
4-hour document session; user had not saved the file, and no cloud
backups were configured.
Environment: WWindows Laptop, Legal Documentation
Software.
Steps Taken: 6 troubleshooting actions (Audited
Windows Event logs for Event ID 41, performed battery health and
telemetry analysis via powercfg, verified physical hardware
integrity of the charging system, searched local temporary
directories for auto-recovery fragments, and reconfigured Advanced
Power Options).
Root Cause: Emergency system shutdown caused by 0%
battery state (device was not connected to power); data was lost
from volatile memory (RAM) because it had not been committed to the
non-volatile disk.
✗ Outcome: Unresolved - Local file recovery unsuccessful; ticket
escalated to Tier 2 for forensic data review.
