Troubleshooting a PC That Won’t Start: The Hair Dryer Technique

Many PC users encounter occasional boot issues, but what happens when your computer refuses to power on unless you resort to an unconventional method like heating it with a hair dryer? This intriguing situation has been reported by a user with a specific hardware setup, raising questions about potential underlying issues with PC components.

Hardware Overview

The problem arose with the following specifications:

• CPU: Ryzen 5 2400G
• Motherboard: Asus PRIME B350M-A (latest BIOS installed)
• Memory: 2x HyperX FURY 8GB 2400MHz
• Power Supply: Thermaltake 600W 80 Plus White Smart Series

All components are relatively new, aged between 1.5 to 2 years, and the system has not been overclocked or had any voltage modifications.

The Issue at Hand

The crux of the problem lies in the computer’s refusal to boot after being powered down overnight. As soon as it is turned off, the next attempt to switch it back on is met with silence—until the user applies warmth using a hair dryer, which prompts successful booting. Once operational, the system functions without issues for hours or even days, casting doubt on any major internal faults.

Steps Taken for Diagnosis

In an effort to pinpoint the source of the issue, several troubleshooting steps have been employed:

1. Reassembly: The system was completely disassembled and reassembled.
2. Memory Testing: Attempts were made using a single RAM stick.
3. Minimum Configuration: The system was run with only essential components connected.
4. Stress Testing: Rigorous tests, including a nine-hour run of Prime95 that peaked at 89°C, as well as Memtest86 and OCCT for CPU stress testing, yielded no errors.

Given the high temperatures and humidity levels typical of a tropical climate (ranging from 24°C to 32°C), environmental factors may contribute to hardware stability. Unfortunately, the user does not have spare hardware components to further isolate the issue.

Recent Developments

In a follow-up, the user reported that after once again shutting down the computer, it failed to start and required another session with the hair dryer. This time, they focused on heating specific areas of the case, avoiding direct heat on the power supply, and aimed for the front and mid-top of the case. Remarkably,
