1) From the devices zapped - "SoundBlaster card and dialup and ADSL
modems, some of my USB ports" - how do you conclude that the surge
problem arrived via the power feed?


2) Being "highly suspicious of the RAM and Processor" isn't much
help. I suggest:

a) Replace the motherboard because there is evidence something is
broken.

b) Run the mfr's diagnostic tests on the hard drive(s), just in
case.

c) Run burn-in tests for 48 hours to check the RAM and processor.


3) A UPS is not a device intended to provide protection from power
surges resulting from electrical storms.

- "You *NEED*.....you *MUST* buy a quality UPS..." - Bullshit. Are
you a salesperson in that line of business?

- A reasonable quality anti-surge power strip should be adequate
for the majority of lightning power surges.
