I have a DZ87KLT-75K board that was working fine. I went to bring it out of sleep, and now it won't go past code 00 12, I've try just about everything I can think of, any help on figuring this out would be great!
Try to clear the CMOS battery, see here for the instructions; http://www.intel.com/content/www/us/en/support/boards-and-kits/desktop-boards/000006488.html CMOS Battery on Desktop Boards
Let me know how that goes.
You had the system completely disconnected from A/C power during the CMOS clear process, right?
Seeing POST code 0x12 indicates that the BIOS started the initialization of the processor. Seeing it stay at POST code 0x12 indicates that the BIOS never completes this initialization. This could be an indication that something in the processor, board, memory or peripherals (including power supply) has failed - but let's not get ahead of ourselves. Please try to collect a little more information. What is the sequence of POST code values that you see before it halts at 0x12?
Hhmmm, I am not sure what to suggest. You could try a different PSU. You could try using a different DIMM. You could try with a different graphics card installed. You could also try doing a BIOS Recovery (documented here: http://www.intel.com/content/www/us/en/support/boards-and-kits/000005630.html?wapkw=bios+recovery Intel Desktop Boards Recovery BIOS Update Instructions; my extra input, if you try this, is to use a USB 2.0 (not 3.0!) flash disk, freshly (re-)format it using FAT32 file system, place only the one .BIO file on it (nothing else!) and use a (black) USB 2.0 port on the back panel of board (not front panel!)).
Hope this helps,
Ooooo, that's a really bad sign. POST code 0x31 is a Crisis Recovery phase and is initiated as a result of the detection of corrupted firmware. Hanging there means it could not complete the recovery (i.e. retries remained corrupted). In an aged board, this is usually an indication that the Flash component has (at least partially) failed.
Sorry, you may have to replace the board,
Al_Hill and N.Scott.Pearson thank you for your inputs.
/thread/109940 Sandmanin as mentioned before there is not much that can be done, at this stage I would recommend taking the motherboard to a computer shop to swap parts. If this does not work I am afraid that the only thing would be replacing the motherboard.
I apologize for any inconvenience.
