've read your other post, watched your videos, and scanned the 'list' you were given to check - man, that
some list! I'm pretty well flumoxed - can't think of much that's been omitted? Thought about it for a while, and came up with just a couple niggling, tiny fragments of ideas:
1 - you mention you 'travelled with it'; but you never mentioned where? Not just being nosy - in the northern hemisphere, it's summer, and for all but a few
really arid spots, the humidity levels are high enough to discourage muchstatic electricity... However, in the southern latitudes, being early-to-mid winter, the air is likely bone dry - making
big sparks! I realize you said you had it padded and anti-statted, but if you
were in a dry clime when you unpacked/reassembled it - I'd have a few more questions for you. I've spent the past 25 years doing industrial systems, have bounced around the globe a lot, and am trying to think back to episodes of 'travel damage' to recall 'causes & effects' - and will keep thinking... (One time, took $50,000 worth of industrial system parts to a country which shall remain nameless; smuggled them in, in
plain view, in a clear plastic box, with an inventory list attached, and $5,000 cash bribe money - at three of four border crossings, my money belt got 'lighter, - but, the parts arrived
with me (not three months later - 'through channels'), and were running the next day! [:bilbat:5] )
2 - if you've done the 'paper clip trick' to test the power supply, it might be worth doing again: be sure to check the status of pin eight, grey wire, 'Pwr_OK'... I recently had a failure like this, and it showed those exact same symptoms -
but - unfortunately, I can
not recall if I was getting the 'POST beep' each time... Here's the deal: when you power up, a timer starts; there's a comparator that 'looks' at each rail, watching voltage on the rail to 'arrive'; the seperate comarators are 'anded' together, and if the result is not 'true' by the time the timer expires, the power OK signal never 'happens' and the CPU does a reset. Was the devil's own time finding it - all the rails were good - I even load tested them a little bit (the little bit limited by my handfull of 20W resistors [:isamuelson:8] ), and only as an afterthought did I check the pin 8 signal (should be a t²l 'true' - at
least 3.3V, more likely 5V)...
3 - did you have to pull the HSF to 'pack' it? Couple of times here, people have described to me what I was
sure were immediate thermal shutdowns, and said they were
positive the HSF install was good - and, upon closer inspection, both turned out to have cracked locking pins - barely visible to the naked eye. The usual characteristic of these reboots is that they get slightly closer together as they progress (usually); couple I've heard of gave the POST beep at first, but after about the fifth or sixth reset, came close enough together that they quit finishing the POST, and failed to beep, before the thermal shutdown happened and reset...
I'll keep thinking - the one good thing is that it
is POSTing - that's always a good thing!
