Troubleshooting PC Boot Issues: Why a Hair Dryer May Be Your Best Friend
Are you struggling with a PC that refuses to power on without a little unconventional assistance? If you’re finding yourself reliant on a hair dryer to coax your machine back to life, you’re certainly not alone. Let’s dive into a case study and explore potential remedies for this perplexing situation.
The Setup
System Specifications:
- CPU: Ryzen 5 2400G
- Motherboard: Asus PRIME B350M-A (latest BIOS installed)
- RAM: 2x HyperX FURY 8GB 2400MHz
- Power Supply Unit (PSU): Thermaltake 600W 80 Plus White Smart Series
This particular setup is relatively new, with components aged between 1.5 to 2 years. Importantly, there have been no attempts at overclocking, and all settings remain at their factory defaults.
The Problem
The primary issue is straightforward: the PC fails to turn on after being powered down for the night. The only workaround? Heating the computer case with a hair dryer. Strangely enough, once the initial struggle is overcome, the system performs admirably for extended periods—often working flawlessly for hours or days afterward.
Initial Troubleshooting Efforts
The first steps taken included reassembling the system, attempting to boot with a single stick of RAM, and minimizing connected components to eliminate potential culprits. Comprehensive stress tests, including Prime95 and Memtest86, returned no errors, even under heated conditions where the CPU reached a notable 89°C.
The climate may play a role here, as living in a tropical area with temperatures ranging from 24°C to 32°C and high humidity levels might affect the hardware’s performance.
Current Insights and Updates
Despite rigorous testing, isolating the problem proved futile, especially without spare parts like a PSU or motherboard on hand for comparative diagnostics. An interesting twist was observed in the system’s clock, which lagged behind even with automatic updates enabled. This discrepancy—where the clock manually synced at 11:39 but fell to 12:19 instead of ticking forward—adds an unusual angle to the troubleshooting conundrum.
In the most recent attempt, the hair dryer was applied cautiously, avoiding the PSU region entirely and focusing on heating the front and sides of the case. After about 4 to 5 minutes of warmth, the system powered on

Thank you for sharing the detailed troubleshooting steps and your system specifications. Your issue of the PC not powering on without external heat suggests possible hardware-related problems, often associated with thermal or contact issues.
Given that the system starts after applying heat, one common cause could be loose or faulty connections, especially related to power delivery components, such as the motherboard’s power connectors or capacitors. Ensuring that all power cables are securely connected and inspecting the motherboard for any bulging or leaking capacitors could be beneficial.
Another area to consider is the motherboard’s power circuitry. Sometimes, cold joints or degraded capacitors can cause intermittent power issues that respond to heat. If possible, visually inspecting the motherboard or testing it with a different power supply might help isolate the cause.
Regarding the system clock lagging, this can sometimes be due to CMOS battery failure or motherboard BIOS issues. Replacing the CMOS battery and updating the BIOS to the latest version (available from Asus’s support pages for your PRIME B350M-A) may improve system stability and clock accuracy.
Since the problem appears to be temperature-dependent, you might also consider monitoring the motherboard and CPU temperatures during startup. Using hardware monitoring tools in Windows or during BIOS post could provide clues about any unusual temperature readings or hardware behavior.
Ultimately, if the issue persists after these checks
