DZ77GA-70K won't boot 2-4-4-2 beeps

[VConi]

I'm trying to troubleshoot a DZ77GA-70K board. I have an i5 CPU (listed as compatible) and get a port 80h (on board LED) code of E6, and 2-4-4-2 beep code. I've changed video, memory, reset the BIOS jumper, hit the Reset button, but always get the same result. I can't find this beep code in the Intel documentation, and the E6 code is 'loading drivers.' Any ideas would be appreciated.

I suggest testing the motherboard with minimum components (one memory stick, no graphics or add-on cards, no drives) out of the case, on a non-conductive surface.

Remove power and CMOS battery for twenty minutes. Try another power supply if possible. Do you get three beeps with no RAM installed?

Thanks for the suggestions. It took me a day to locate a suitable power supply to try, but no dice. Same problem: E6 and 2-4-4-2 beeps. I'm really confused by the beep codes as 2-4-4-2 sounds like a Phoenix code, not an Intel code.

To answer your questions, I am trying with nothing connected (no USB nor video headers used), no cards (except video) and yes, I do get 3 beeps with no RAM installed. I'm coming around to the board being bad, but I wanted it to work and felt I should try everything. Any other ideas, or I'll just toss this one on the recycle pile and get on with other things. Thanks again.

You may try a BIOS recovery. http://www.intel.com/support/motherboards/desktop/sb/CS-023360.htm Desktop Boards — Instructions for Recovery BIOS Update

Otherwise, see if the board was purchased within the last three years for warranty replacement. http://www.intel.com/p/en_US/support/contactsupport Contact Support
