It is about 7.3 years old. It has a two digit LED display on it. When the motherboard worked correctly, the display would quickly increment until it reached FF. Now it gets to C1 and stops.

I cannot find the paper manual for the board. I think I have a digital copy on one of the hard drives in the system which I cannot access now. I went on the Epox web site and it requires a user name and password to download the manual.

Does anyone know what the C1 on the LED display means? Does anyone know where I can download a manual for this motherboard?

One more thing. Look closely on the motherboard, if any capacitors look like this: http://www.rom.by/images/wiki/f/f9/ECAP_PUHL2.jpg or this: http://www.rom.by/images/wiki/1/19/Bad1.JPG, then it is time to go for parts and soldering iron.

PS. No, I haven't found the manual. I found the information on some forums and confirmed this in the manual for my "port-80" tool.
