Replacing bad caps

My Epox 8RDA+ just died presumably due to the bad caps (they are bulging,
leaking). After months of taking 2 or 3 tries to boot (good a "no video
signal" error message and never saw a boot screen), it finally would not
boot at all. I put in a spare 8KHA+ and am up and running again. Wondering
if anyone has successfully replaced the bad caps and got a dead mobo working
again? I don't really need it except as a spare.

Easy to do. Better off ripping the cans off and soldering onto the legs
that are left than trying to desolder on a multilayer PCB.

If you want to spend a little money to repair it, check out this site.
They do repairs and have been around for years, so I would assume
they're reputable.
http://www.badcaps.net/

Check the left side near the top for "Repair Services".

I like doing things myself, but replacing these caps, as mentioned, on a
multilayer motherboard, is very difficult (unless you're really good at
it ;-) ).

Thanks for the suggestion but I don't think I will spend $60 on this mobo.
I could probably find one on Ebay for half that (knowing that it might have
failing caps also.)

Heartily agreed after my failed attempt to desolder and resolder caps to
yet another bad gigabyte board...

The cap kits can be expensive, it takes work, and you are not assured
success. I would set up an ebay search for a new-old-stock (NOS) mobo
of a different make or model. When you find one, use google to see if
that board gets capacitor or other problems. If not, buy the board and
do a repair install (assuming XP).
 
I replaced the bad caps on an Abit MoBo and the thing works fine.Someone here
recommended a company from Hongkong.They advertise on Ebay. I bought a bag of 30
1500 µF 6.3V nichicon 105° caps from China on
Ebay. The caps were $10.99 and shipping to Canada $5.99. BTW they do mix and
match 1500/2200/1000 micro F.

Here is one such auction:

I'd be wary of buying Nichicon or Rubycon caps on eBay. These two
brands are often counterfeited.

Check the dimensions against a Nichicon datasheet.

Recently I found "Rubycon" caps in the PSU of a $29 DVD player. The
dimensions for the 25V and 16V caps were identical. Comparing them
with the Rubycon datasheet confirmed that at least one was fake. An
identical PSU in another supermarket player had off-brand caps which
had either swelled or exploded.

I tried it once.

I took good caps off of some scrap boards I had and replaced all the leaky
caps on a board I was
trying to repair. However, it was still flakey...so I assume there were a
few bad caps that just had not started to
leak yet...so don't waste your time.

To go out and buy news caps is moderatly expensive...
an entire new mobo's don't usually cost that much anyway.

To send the board out to have some shop repair it
would almost certainly exceed the price of a new board/

I have repaired a number of boards Lee. Tedious but
successful. I replaced every cap since they were all destined
for failure. All were Abit boards.

I have some left over that I would consider selling at cost if
you are in the USA.
