I've recently purchased this product in factory condition and it is unable to get past the POST codes. First I started troubleshooting and made a little progress. I had an error code E2 which was caused by wrong RAM placement, but now the system automatically restarts when it gets to POST code 92, which is supposedly keyboard precense detection. There is no error code on screen or any beeps, it just silently reboots and the same thing happens once again.
I have tried the following things which didn't work:
I am not currently using any PCI devices - only the bare essentials are in use. Now I am out of ideas of what to do, and google searches have not helped me any further than solving the wrong RAM placement issue (Code E2). Got any suggestions for further troubleshooting?

You could try with a BIOS recovery, see here for the instructions http://www.intel.com/content/www/us/en/support/boards-and-kits/000005630.html Recovery BIOS Update Instructions for Intel® Desktop Boards, and here for the download https://downloadcenter.intel.com/product/63244/Intel-Desktop-Board-DZ77GA-70K Drivers & Software, I would recommend doing the recovery to the same BIOS version you have installed.
