Hi everyone,
Just looking for an outside thought as to what might be wrong with a motherboard I have.
So basically got a Supermicro X8DT3-F a while ago (dual socketed 1366 board btw) and it tested fine using an Xeon E5520 and 3x 4GB DIMMs. Since then it has been sat in a chassis waiting for some new processors to arrive.
So yesterday, the new processors rolled in. As the board had an older BIOS on it, I thought to update the BIOS before installing the new processors. However, when I plugged the PSU back in to power the unit up there is no sign of life at all.
The Heartbeat BMC LED lights up and starts blinking (which denotes that it is active and functioning) which means the board is getting standby power to it. Although when the power button is pressed nothing happens, the onboard power LED does not light up nor do any of the fans spin up.
I've tried a different PSU, CPU and RAM, just to be safe and checked the board was not shorting against the chassis (which it wasn't).
If anyone has any bright ideas of how to resurrect this board, please do tell. Although I am thinking that there was an underlying problem to begin with.
Thanks to any fresh ideas

Can you still get to the ipmi? Often it is the case that ipmi and bios mist handshake. On cold boot many boards will not post until the ipmi has indicated a ready state.
If there is a disable ipmi jumper try that.
Also make liberal use of the reset bios jumpers and pop the battery.
Well the IPMI had not been configured as of yet. But the LAN port for it indicates that it is functioning.
There is no jumper to disable the IPMI, but one to disable the BMC. Although disabling this does not have any effect either.
I also forgot to mention in the original post that I had been using the reset bios jumper quite liberally.
Leave the system on for 5 to 10 mins. Perhaps its taking a long time to initialize.
You may be able to get into the ipmi with a default IP to diagnose further or even reflash the bios
Within the IPMI (that thankfully assigned an IP via DHCP) I try to power on the board within their and it fails to do so.
Unfortunately to flash the BIOS on this series of boards requires that you boot into DOS and flash it from there.
However looking at the Event Log, there is a major issue with voltage...
Looks as through your power supply is having trouble supplying clean power. Try another power supply, drop down to one CPU if applicable (but if the mobo has dual 12v 8 pin, or 8 pin + 4 pin, make sure both are connected even with just one CPU)
I was already only testing with one CPU, although this is also what I suspected and I have tried a different PSU. But alas it still won't boot.
I shall test with yet another PSU tomorrow just in case.
Thanks for all your help so far.
But as a side note, upon trying to power the board on, not even the PSU fan spins up.
After taking the hit of powering down another supermicro server I have with a known good PSU and connecting to this board, I get the same output as above into the event log.
With both the PSUs I tested before running perfectly fine on the other board.
Looks awfully like the voltage regulators on the board itself are dead.
