At Badcaps.net, I've read that some brands of caps often fail without
bulging. OTOH when I replaced about a dozen 1,000uF, 6.3v Ltec caps
on an Asrock mobo, only the three that bulged were bad, according to
ESR readings.

I haven't done much checking, but the $50 mobos I've seen had at least
some low quality brand caps on them, and boards with only good caps
start at around $75.

actually I got some decent deals from NewEgg.

One of the boards was very good quality...it was an "open box" special.

The other was also pretty hi-quality board...but just slightly old
inventory.

I really do not need state of the art equipment here as I give all the
hard work to my GF <G>

Depending on board design, if too many in the same
subcircuit fail it can exposed the ICs to high ripple which
could damage them. Other times the board just had a
different fault altoghether and you notice the caps bulging
because the other fault prompted an investigation with the
cover off the system.

Depends on the age of the board, role of the system, if it's
your system, etc. Sometimes people will bring me a board
that had caps fail but they can't or won't spend much
money, and I happen to keep a stock of spare caps suitable
for most boards though not so much the solid caps many use
today but they fail far less often.

Replacing caps also cuts down on system downtime and time
spent reinstalling or reconfiguring the OS if/when the
replacement board isn't the same model... seems I often buy
boards when I see good deals on them but to try and replace
with the same board later it seldom seems to be worth paying
more to get the same thing again instead of an upgrade of
some sort IF buying a new board seemed otherwise the best or
necessary option.

What I often do is buy a board to match I cpu I already have.

Last year I got a couple of eMachines in here with bad motherboards...
but they had perfectly good dual core cpus's I did not want to waste.

So thanks to some deals at NewEgg, I was able to build a few machines
for next to nothing...I literally have boxes of spare parts in my workshop

Me too, then eventually I need to clear out space and end up
throwing away some stuff because there's always 2/3rds of a
system built... if only I bought another X, Y, or Z part to
finish one. Right now I'm staring at a 1.1GHz Tualatin
system with a motherboard that I replaced the caps in about
5 years ago, it used to be mainly for internet and office,
but all the flash video and ads on the internet today it
can't handle very well so it gets demoted to a lesser job.

Oh

NO

don't throw anything away


Seriously! next time you have stuff to toss Ping me

or gmail philo565

I will buy it from you (not anything too heavy to reasonably ship) I
need to support a Non-profit org.


I especially need obsolete mobo's of the P-III vintage

.... but then what will our garbage man do for spare parts?
It's funny sometimes watching him root through our garbage,
sometimes he just takes the whole bag or box and puts it on
the seat next to him, not even realizing he took the wrong
bag, lol.

I suppose I just get into the habit of tracing faults and
trying to fix them... even if the hardware never gets used
again. Earlier today I picked up a couple LCD monitors,
both had bad caps on the output of their internal power
supply. CapXon capacitors apparently aren't fit for use in
these circuit placements.

I don't toss any computer stuff in the garbage...
I drop it off at the recycler

I don't usually bother to repair stuff on the component level...
unless it's something highly critical
