| We solved a similar problem. Lightning struck an AC wire far down the street. Damage is always on a path from lightning to earth. Incoming on AC mains. Incoming to the computer and all-in-one printer. (Both on a surge protector that did what the Earthlink tech also said it does - only protect from surges too small to cause electronics damage). |
If the surge only has an incoming path, then no damage can happen. But an outgoing path from the printer was via the phone line. And to earth via the FIOS box (FIOS box also damaged). Damage is only on a path from lightning to earth. Fixing damage means both the incoming and outgoing path (through printer and computer) are identified.
BSOD has numbers that are critical. Without those numbers and the associated text, then every reply can only be wild speculation.
Printers are harder to fix. In that above example, an incoming path was via the printers USB port. The outgoing path was via a fax phone line. I replaced the phone line surge protector that failed. That completely restored fax service. The USB port connected to an IC I could not replace. So the printer now runs just fine as an ethernet device.
Appreciate the concept. Having identified the incoming and outgoing path, then the printer now works just fine (except for a failed USB port). That surge went through the printer. But only damaged specific parts. All surge damage is that simple. Hardest part is identifying a surge current path.
What was the incoming and outgoing path through your computer? Numbers from a BSOD are an excellent place to start. Do not make the problem more complex by swapping parts. First identify critically important facts. Changing parts comes later.
