SHC, I'm sorry to hear that you are having issues with this board. However, I would need to get additional information on this behavior.
-Do you remember which the current BIOS version of your motherboard is?
-Are you getting any beeps from the motherboard?
-Could you please take the board out of the chassis and test it using minimal configuration (motherboard, processor, power supply)
- Test the system without memory and check if you are getting 3 beeps.
- You could try to clear the CMOS again.
-Then, include 1 memory stick and try to access the BIOS screen pressing the F2 key. Run default settings.
Let me know the results.
