What to Do When Your PC Refuses to Start After a Lightning Strike

Experiencing a power surge during a storm can be a harrowing event, especially if your computer is plugged in and actively being used at the time. One user faced exactly that scenario when their PC sparked and shut down abruptly due to a nearby lightning strike. If you’ve ever had a similar experience, or if you just want to be prepared for the unexpected, read on.

The Incident

While using the computer during a thunderstorm, a lightning strike caused a significant surge that resulted in sparks emanating from the inside of the machine. After the initial shock, the user attempted to power it back on; however, nothing worked—no lights illuminated, no fans whirred, and it seemed as if the system was completely lifeless.

Determined to diagnose the issue, the user opened up the case and attempted to reset the CMOS, but to no avail. Suspecting the power supply unit (PSU) might be to blame, they inspected it and discovered traces of melting inside, leading to a decision to hand over the hardware to a professional for repairs.

Professional Help and Diagnosis

The technician replaced the old PSU with a new unit, but the PC still refused to boot. At this point, the user grew increasingly anxious, fearing that their entire setup could be compromised. They posted their specifications online in search of advice and reassurance. Here is what they shared:

• Processor: Intel Core i3-3220
• Memory: 8 GB RAM
• Power Supply: Litepower 650W Thermaltake
• Graphics Card: GTX 980

Additionally, they mentioned their Ethernet connection and that the router had also failed during the electrical event. Thankfully, there was no noticeable burning smell from any components within the case.

The Outcome

In an unexpected twist, the technician managed to repair the computer, confirming that the motherboard was the primary component that had failed. Fortunately, the rest of the setup was intact.

Conclusion

If you find yourself in a situation where your PC doesn’t power on after a storm, it’s crucial to take the necessary precautions before troubleshooting. Always consider seeking professional help, especially when dealing with electrical components, as they can be sensitive to surges.

For peace of mind, ensure that your hardware setup includes surge protection to shield against future incidents. By being proactive, you can safeguard your equipment and help prevent costly repairs
