Roland, would you please take the board out of the chassis and test it using minimum configuration (motherboard, processor, power supply)?
If you get 3 beeps, please insert one memory stick on DIMM #1 and turn on the system.
In the other hand, if there are not beeps at all, you would need to test the processor on another motherboard, or test a different power supply?
Would you please provide me the model number of the power supply you are using?
Remember that the motherboard is still under warranty, so you can get in touch with our Warranty Department so they can help you to replace the unit: http://www.intel.com/p/en_US/support/contactsupport
I tried it with 2 power supplies, no differences :
be quiet! Pure PowerTM L7 350W be quiet! Silent PSU & Cooling for your PC
be quiet! Straight PowerTM E9 400W be quiet! Silent PSU & Cooling for your PC
The board does not beep with or without memory.
It only beeps when I hold the power on button and switch on the power supply.
The question now is is it the Board or the Processor, both are under warranty.
