Gigabyte GA-K8VM800M recap worked but now dead?

Hm should work fine for a motherboard, check that they are all soldered properly including polar direction and the actual solder joints.

Some of Gigabytes motherboards require much lower ESR values than HM series. Especially the VRM outputs. Also we do not know exactly what he replaced the original caps with. Real or fakes? Also some socket 754 boards a finicky about the DDR choices. A lot yet to be confirmed.

Sometimes Nichicon HM is not quite low enough ESR replacements. Try resoldering/ reheating the caps just incase of a cold or incomplete joint exists somewhere. It is easy to see the solder on the bottom of the board but not on the top being covered up by the caps bung.

Hi,
Thought I'd try out a 64 bit motherboard
It's very tidy with no scratched traces

I recapped this motherboard's input and output VRM caps (previously had bloated output caps) with new HM's.
And after a few days of it running nicely, just when i had nearly finished with sorting out a dual boot, it packed a sad.
What happens now is this:
When the wall socket switch is turned on, the computer starts immediately.
Then it makes a long high pitched beep followed by (a few seconds later) a long low pitched beep then nothing more (not repeating).
Using the computer power button, the machine can be powered down (and also restarted after pushing it again).

I have removed the board from the case, disconnected all periphial devices and IDE cables - same result as above
Tried another CPU - same result as above

No video display from either the onboard video or the AGP video card (when inserted)

Tried another PSU - no difference

Tried different RAM/slots - same result
Removed all RAM - get correct repeating beep code for missing RAM

Seems that the Award BIOS is at least partly OK

Any idea what to look for next?
