Machine no longer boots

[sheepdot]

Hi all,

This is probably a bit out there for a FreeNAS forum, but I'm hoping that since I bought recommended hardware some of you may have had similar experience with the same components.
My motherboard is a Supermicro MBD X9SCL-F-O. My PSU is a Seasonic SSP-450RT. I bought these all almost four years ago, and they have been running great. I have changed nothing in the past couple of months. In the middle of streaming a TV show tonight, the system cut out. I was able to connect using IPMI, but the system would not post. I checked the physical device, and the IPMI light is blinking on the motherboard, but hitting the power switch doesn't start any of the fans.
I disconnected the PSU and jumped the power on the PSU with a paperclip, which started it up, and tested all the lines with a voltmeter; it appears to be fine. I've gone ahead and ordered a new PSU (hope springs eternal), but I was wondering if you all had any additional troubleshooting I might try. I would ordinarily hook up my PCI motherboard tester card... but this board only has PCI-E.

Any suggestions?

Try removing all but 1 stick of RAM.

Thanks for the suggestion; I tried it, but no change.

While the PSU is disconnected, hold the power button or jump the pins for 60 seconds.

So disconnect the PSU from the motherboard and then hold the power button on the case or jump the motherboard power switch pins for 60 seconds?

 

[Sakuru]

Correct.

What does that do?

 

[Sakuru]

It drains all power from the motherboard. It probably won't help, but it's one of those things you do as a last ditch effort.

 

[sheepdot]

Nope, no change.

Well, thanks for the help!

It turns out the PSU was, in fact, the culprit. Unfortunately, I have a new motherboard en route... hopefully I can return without a restocking fee.
