I have the following motherboard:
Intel Desktop Board D865GBF/D865PERC
It also has E210882 Silkscreened on the board.
There is a bar coded label which reads: ABBF41428624 AA C25843-407 (I assume that C25843-407 is the serial & revision)
The board was given to me as not working and its history is unknown.
The problem with this board is that it does not boot up. The fan just turns on power up and then nothing.
PICTURES (NOT mine but SIMILAR)
While the picture below is not of my motherboard, it is nearly identical in looks.

The following picture is clearer. However it is different in that the BIOS chip is in a socket. Also the yellow capacitors in line with the CPU socket are different. Mine are metaalic with blue markings on top as in the previous picture.

The board has the following capacitors (hopefully the above pictures will aid understanding my text):
1. 1x nichicon 2200uF 10V capacitor near the SATA-1 connector. This was bulging so I replaced it with a Rubycon 2200uF 6.3v. Is it ok to do that? The capacitor value is the same but the voltage is lower.
2. 4x nichicon 1200uF 16v capacitors (also marked HD(M)) between the CPU and the back panel connectors.
3. 5x Rubycon 820uF 6.3v, 3 of them by the cpu socket, the other 2 are at each end of the DIM socket nearest the CPU
4. Then there are numerous other small nichicon capacitors peppered about the board.
Other than the nichicon 2200uF 10V, in item 1 above, all other capacitors look OK. No bulging or leaking.
Replacing the nichicon 2200uF 10V with the Rubycon 2200uF 6.3v has had no effect.
My questions
Does anyone know whether my problem is related to bad caps? If yes what capacitors are the likely culprits?
Can this motherboard be saved? Or will other components have been damaged?
I have some more Rubycon 2200uF 6.3v in my spares, can I replace the 4x nichicon 1200uF 16v with these?
What is the rule for replacing capacitors in terms of their values and voltages? I have a number of capacitors available but not the same values/voltages.
I hope someone knowledgeable with this board can help.
