In addition to the standby power indicator, the board contains two LEDs that indicate the following:
- The Processor LED indicates an elevated temperature on the processor that could effect performance (RED)
- The Voltage Regulator LED indicates an elevated temperature in the processor voltage regulator circuit that could effect performance (RED)
I would recommend you to check the power supply and make sure it is working fine, else it could damage the board or the processor if there are fluctuations. Also, you may check that the memory that you are using is1.6V and not more.
Hope this will be helpful.
This is the 2nd mobo and 2nd i7 920 that this has happened to. I exchanged both for the current mobo and cpu. The p/s is a 500 watt and appears to be functioning correctly. All the fans seem to be working. I do notice that I am not getting any video.The memory is DDR3 1333 Corsair the version that Intel suggested. I did remove the memory but still no beeps. Any other ideas?

Okay, it does seem strange though.
However, can you check the revision of the board - should be something ending with either -501 or 502. Also check if the have the D0 Stepping of the i7-920 processor, by checking if the SL number is SLBEJ. If this is the case, then there is a great probability that it will not work as they are not compatible yet, unless you update the bios with a C0 stepping of the processor.
If this is the case, then it has already been discussed in some previous posts: http://communities.intel.com/message/23221#23221
This is the only way this combination of cpu and motherboard may not always boot or give any video or beeps. Another simple test would be to test the motherboard out-of the pc case just to make sure there are not short-circuit.
That's all I can suggest so far. Hope this is helpful.
Here is the mobo rev. It is 503 and the cpu is SLBCH. I also noticed that the onboard power switch does not do anything. I am beginning to suspect that this board is defective. What say you?
