I've got a Gigabyte motherboard from the same
period with the issue ...
three caps on the board are bulging or split on top. I bought three of
the same model boards at the same time and only one of them have had
that happen.
The cap failure is due to a formulation error. The formua was stolen
from a competeing cap mfr, and they got it just a
little bit wrong. There
was a big write up about this when it was first
discovered.
