Power failed due to the storm. What signs indicate a damaged PC?
My computer was connected when it got windy and power went out before I could check. If it turns on and appears fine, is everything okay? Could damage be more subtle? I use a surge protector, but I've heard those can fail sometimes. I'm anxious and don't want to waste the week pretending everything's normal when there might be something wrong (like slightly lower FPS, longer boot times, or minor stuttering).
there aren't any spikes when power comes back on initially. I was worried they might cause harm. I'm not sure what to watch for if something goes wrong.
Not really a specific test for the PC beyond simply using it.
If your surge suppressor has a test mode or indicator light showing it’s functioning, you’re in good shape. If not, it’s time for a replacement.
Power fluctuations can occur when mains electricity returns after storms or due to physical damage or lightning strikes. Even nearby lightning can affect wiring in your home or utility lines. Computer power supplies are reasonably effective at handling these issues, thanks to MOVs and bulk capacitors that protect internal parts.
The surge suppressor’s role is to stop any high voltage surges from reaching the system.
Will it clearly show issues after electrical damage? Might it stop working or become nearly non-functional?
Computers usually function as either working or not working. When they don't operate properly yet an OS is running, it's typically a software problem. Sometimes memory problems can lead to system behavior issues, such as crashes or visual artifacts on the screen.
Some parts may malfunction. Network adapters can be affected by electrical surges. Older telephone modems were also prone to damage. This often required replacing the modem or NIC, which is why surge protectors are frequently included with telephone and Ethernet ports.
Hard drives, tape drives, and floppy drives can fail after storms, but all other main system parts usually remain intact. It depends on how well each hardware component is protected.
Surge protectors can indeed fail, and they are tested for the amount of energy they can handle (in joules) before they stop working—meaning protection ends.

Another useful approach is to tune into Reliability History/Monitor. It’s very user-friendly, and the timeline view might help spot trends.
Just keep an eye on any error codes, warnings, or messages that appear for the first time. These can act as early alerts.
Note that some entries will always be logged by the system, so all records are captured.

Don’t forget to back up critical data at least twice, storing it in separate locations away from your computer. Make sure these backups are both recoverable and readable. You should already be handling this.
If there were any problems from the mains affecting the computer, the symptoms would become evident almost right away. Over time, determining the exact cause becomes more difficult. The situation might simply involve a faulty hardware unit, malfunctioning software, or an unintentional static discharge.
If the computer seems to function properly now, don't be concerned. However, if you're concerned about data loss, it's wise to have backup plans in place.
