Troubleshooting Random PC Shutdowns: A Step-by-Step Guide

Experiencing unexplained shutdowns can be frustrating and disruptive. If your computer was functioning normally but suddenly begins shutting down randomly within minutes, it’s essential to systematically identify the root cause. This article will walk you through common troubleshooting steps, including hardware checks and diagnostics, to help restore your PC’s stability.

Understanding the Issue

Recently, you observed that your PC was running smoothly but started shutting down unexpectedly within approximately 10 minutes of operation. Notably, the shutdowns occurred even when the system was in the BIOS environment. Such behavior indicates that the issue might not be solely software-related but could involve hardware components.

Initial Troubleshooting Steps

1. Check Hardware Temperatures

Monitoring component temperatures can reveal overheating issues that may cause automatic shutdowns to protect hardware:

• GPU Temperature: 35°C
• CPU Temperature at Shutdown: 48°C

These temperatures are within acceptable ranges, indicating that overheating is unlikely the cause at this point.

1. Reseating RAM Modules

You tested your RAM modules by:

• Removing and reinserting the RAM sticks.
• Using different RAM slots.

Since the problem persisted, it’s unlikely that faulty RAM seating is the primary cause, but it’s always good to verify each module individually if possible.

1. Power Supply Unit (PSU) Checks

The power supply is critical for system stability. You used ChatGPT’s guidance to measure the 12V rail voltages, which ranged between 12.040V and 12.070V. These values are within the acceptable tolerance range for most systems, suggesting that the PSU may be functioning correctly in terms of voltage output.

Recommendations for Further Diagnostics

Although initial checks didn’t indicate obvious faults, persistent shutdowns warrant a deeper investigation:

• Test with a Known Good Power Supply:
  Swap your current PSU with a reliable, known-good unit to rule out power issues.

• Examine System Logs:
  Check Windows Event Viewer or system logs for any errors or warnings leading up to shutdowns.

• Monitor Temperatures and Voltages Under Load:
  Use tools like HWMonitor, HWInfo, or SpeedFan to observe real-time data during system operation.

• Conduct Stress Tests:
  Run stress testing software (e.g., Prime95 for CPU, FurMark for GPU) to see if the system maintain stability under load.

• **Update Drivers and BIOS
