We had this issue a few months ago. If you press 'reset' the system will come up with a BIOS error as per the above post. Intel could not reproduce the problem. So you can either just sit and wait for the display to arrive - because sometimes it never does, or you can press 'reset' and go through the BIOS error then press 'n' and system will boot fine.
Sorry, but the customer has the system now so we are unable to do further testing. Also, because the customer has the system, I can't even give you the revision number on the board. We found though that the video didn't come up on VGA or DVI either, not just HDMI, and we tried multiple different monitors - including old fashioned 4:3 monitors too.
Pwertz, could you please check the information given by the user Aleksandr on the following thread https://communities.intel.com/thread/47507
" Hello worked fine. Only enabled Legacy Mode and UEFI mode on. Now show Intel Logo. You do not have to enable intergrated graohics, only enable Legacy Mode"
Please let me know if you could follow those steps and then provide me the results.
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.
CaptainIND, have you tried all the troubleshooting giving on this thread?
Which the current BIOS version of the motherboard is?
Regarding the error you are getting, could you please try to access the BIOS and under the “Performance tab” please disable “Failsafe Watchdog”, then reboot.
Let me know the results
Thanks for your quick response. Hope you understood my pathetic situation.
I have updated the BIOS version and its now -
BIOS Version/Date Intel Corp. MCH8710H.86A.0154.2014.0123.1542, 1/23/2014
The processor is -
Processor Intel(R) Core(TM) i3-4130 CPU @ 3.40GHz, 3400 Mhz, 2 Core(s), 4 Logical Processor(s)
Ram : Adata 4 GB. Model No: U-DIMM DDR3 1600 4GB.
SSD: Samsung MZ-7TE250BW
iBall Wireless Mouse, Logitech wired Keyboard and Samsung OCTOedge DVD writer.
I have disabled FAIL SAFE Watch dog as well, but no use.
Please help me.
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.
CaptainIND, I’m sorry to hear that you are still having problems with this motherboard.
Which operating system are you using?
According to the processor information you gave us, it comes with HD Graphics 4400. I could recommend you uninstall the current graphics drivers and install them again. These drivers are for Windows 7, 8 and 8.1 operating systems.
Have you tried using the DVI-I port just for testing?
Have you tried another HDMI cable?
You could also try to reinstall the latest BIOS.
