Hi,

First of all, well done for creating such a forum! Great job! It's my first post, so excuse my newbie talk.

I've bought an Tyan S7050 and 2x Xeon E5-2660.
The board seems to be temperamental as it booted well for a few times and then after reset it, stop working. It start all the fans, CPU's inclusive, but doesn't post. Either using a PCI Graphics card or integrated. Sometimes it "looses the power and restarts"

I've tried the following parts:
Boot just with 1 CPU power connector on both power supply connectors,
Remove the PCI graphics card
Remove the audio card from PCI
Reset BIOS

I didn't update bios or did any change in the system. It was just a normal reboot from Windows 10.

I've tried to check the user manual but no reference to this amber LED (LED_2). Heart beat LED is Green

Any suggestion?

Thank you very much!
