Understanding PC Damage from Cyber Storms: What to Do After a Lightning Strike

Experiencing a thunderstorm while using your computer isn’t just a minor inconvenience—it can lead to serious hardware issues. Recently, I encountered this alarming situation myself. As I was working, a lightning strike caused sparks to fly from my PC before it powered down completely. This unexpected interruption sparked a wave of anxiety, leaving me uncertain about the condition of my setup.

Upon attempting to restart the computer, I was met with silence—no lights illuminating the case, fans refusing to spin, and no signs of life whatsoever. This situation prompted me to investigate further. After opening the case, I reset the CMOS (Complementary Metal-Oxide-Semiconductor) in hopes of reviving the system, but to no avail.

Diagnosing the Problem

Having assessed the situation, it seemed highly likely that the power supply unit (PSU) was compromised. A visual inspection revealed some alarming signs: trails of melted components inside the PSU. Realizing that this was beyond my expertise, I opted to consult a professional technician. After explaining the issue, the technician replaced my old PSU—a LitePower 650W by Thermaltake—with a brand-new unit.

However, even after the replacement, my computer still remained inoperative. At this point, I felt a wave of dread—was my entire setup doomed? Would I need to replace just the motherboard, or was there something more sinister at play?

Insights and Reassurance

Fortunately, I have some good news to report: the technician successfully diagnosed the issue. The root of the problem was indeed a fried motherboard, rather than a complete system failure. This outcome reassured me that in the face of such adversities, professional help can make a significant difference.

Conclusion

For anyone who finds themselves in a similar predicament, it’s crucial to assess both visible and hidden damage to your computer after a storm. Key components like the PSU and motherboard are often the most vulnerable to surges caused by lightning. If you’re uncertain, don’t hesitate to reach out to professionals who can accurately diagnose the issues and save your beloved rig.

As for my own setup, I’m relieved to report that it’s on the mend, and with a new motherboard and PSU, I am looking forward to getting back to my usual computing routines. Remember, take precautionary measures during storms, such as using surge protectors or unplugging your equipment, to mitigate these risks in
