Hello Maninholj,
These are some recommendations for this issue:
- Remove the CMOS battery and leave the system without it for about an hour. Then put it back on and restart the system.

- Test the system out of the chassis with minimal configuration please. (Motherboard, processor, power supply, 1 memory stick on DIMM #1)
-If you continue having the same behavior, and if the motherboard is still under warranty, please 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
