I really don't know where to post this, because you will see it
applies to all mobos that use Taiwan caps, capacitors for short.
I have a Gigabyte GA-7VAXP Rev. 1 mobo, I usually do an inspection and
a 'dust down' at various intervals, this time I noticed one cap has a
swollen top, these are the weak point of the casing for if there were
no 'vent's the darn thing would explode like a firecraker, leaving
silver foil all over the mobo which could cause short circuiting and
complete damage, the gunge they leave behind is very corrosive and
will 'rot' the copper tracks on the mobo in no time.
Should I leave it or change it, well, I decided to change it - just to
be on the safe side and to save possibility of further damage, you do
really need good soldering practice and a little knowledge to do this
operation, the mobo was working fine but this time I felt "if it ain't
broke I had to fix it" or damage could easily have resulted at any
time.
The are two identical caps near the yellow socket, only one was
affected, they are green and are 1200uF 6.3 Vdc, whatever you do
computers must use capacitors with low ESR and 105 deg C temperature
rating or greater, standard components could literally explode at
'switch on'.
The type I used are Panasonic 1200uF 10V dc, these are low ESR and
rated at 105 deg C. Part # EEU-FCA122, if you can get better ones use
them.
Now I diverse:
I did say this applies to all mobos...indeed it does as you will se if
you follow the links given, all capacitors made in Taiwan are suspect
and this applies to all mobos, apparently the worst ones reading the
Web are Abit which appears to stick out like a sore thumb.
They type in question with the Gigabyte are the GSC green ones, note
this is not saying all GSC types are bad, in this board the two to
look for are the two green ones near the yellow socket and the two
near the ram chips and CPU, this is the version 1 mobo I refer to
here.
The reason for these Taiwan bad caps is purely company Espoinage..!

Enjoy reading.... If you want more do a Google, for motherboard and
bad capacitors.
