I am sorry for this issue.
Unfortunately, I was not able to replicate it. I may suggest testing with a different power supply; we have a list of tested components in the link below.
You may also want to post your system configuration in case the issue persists so we can further assist you.
Thanks Joe. We will try a different power supply to see what happens.
Full system specs are:-
Core i5-4670 3.4GHz
1 x Kingston KVR16N1/8 but also tried 2 x Kingston KVR13N9S8/4
2 x Western Digital WD1002FAEX (also tried with just one)
LiteOn IHAS120-OEM dvd burner
Acbel G550 power
Gainward GT640-2G - we've also tried without the graphics card
Whenever power is removed from mainboard and system fails to POST - there is a longish beep that according to technical specs advises that BIOS is available to accept keyboard input - but there is no video to indicate the same.
We've done further testing this morning and found that the system boots to the BIOS after cold start if we actually disconnect all hard drives. Woud UEFI have anything to do with this problem? There doesn't appear to be any problem with the drive as under warm boot situation it has been running perfectly.
We think we finally have an answer to this problem. It is the WD black caviar drives. We loaded a Seagate Barracuda Green 2Tb (ST2000DL003) and it cold boots just fine. As we don't stock Seagate any more because of Seagate's pitiful 12 month warranty, we only stock and sell Western Digital Black Caviar drives which have a 5 yr warranty. Can Intel please test the WD black caviar drives with the DH87MC board?
sorry for delayed reply. customer had taken computer because he needed it and we had to ask for him to return it for a weekend to try some other things. We found that by moving the drive from Sata port 0 to sata port 3, the problem went away. Not sure if we just have a 2nd faulty board, or if there is an issue with these boards combined with wd1002FAEX, UEFI and Cold boot. By the way BIOS settings are default. Also, when you are testing cold boot, the system needs to be powered off for a few minutes, not just a few seconds.
We are having the same issues and more here - I have 4 DH87MC's that are have post boot problems and Blue screens- all fresh loads..
I was just told by phone support to move my hard drive to port 1 and CD to port 2 - I also only use WD drives-
He also wanted me to change the video driver to a driver not listed on the board's WEB page but is a HD4600 Graphics driver..
RAM 4x4G sticks of Crucial BLS4G3D1609DS1S00

Hi Bob, Did you ever find the answer to the DH87MC boot problem? I gave up. The latest BIOS did nothing to fix the issue and now others are finally reporting the same issue. Re: DH87MC
If you found an answer, we'd love to hear it.
I got my newly configured PC on last Saturday(04/26) since then am experiencing a lot of problem with the DH87MC Mother Board because its NO HDMI Video while BOOTING after complete system power shutdown.
When I starts PC even after 1 hour from complete power shutown, the mobo starts with a beep(i guess its no video detected warning) and thereafter no visuals in my Samsung S23B370 screen. But the CPU fans everything seems to running. When I restarted PC by pressing CPU power button for about 10 seconds and switching it again - the mobo shoes an error message "BIOS HAD DETECTED AN UNSUCCESFUL POST ATTEMPT(S). Press 'Y' to enter setup or 'N' to continue normal.
I have a seen a lot of threads here asking similar kind of helps - without any successful answers.
Please help me to solve this issue.
Hi CaptainIND, I recommend you following up in the other threads where you have also posted since Sylvia_Intel is already helping you:
I have tried every possible way to nail down this issue. Gone through every thread describing about mob boot issue.
Also, I have switched on my audio device and am not getting "intel inside audio" and i noticed that there is no signals on keyboard as well. Usually after a successful BIOS load i can hear the intel inside audio and a LED glowing in Keyboard(the num lock LED will be glowing in case of success). But during the issue time, am not getting any audio nor keyboard LED notification.
Everyday am getting once or twice this problem.
I have updated the latest BIOS and Intel HD drivers.
