I had a lightning strike near my house, probably a tree. It did not
strike the power/phone lines but was close enough for an EM pulse. I
lost a PC that was disconnected at the time, some of the flash memory
was wiped and the CRT TV was gaussed.
As for diagnosing, I'd start with power supply. Disconnect and test
with a volt meter.
