DH87MC boot problem with new monitor

Jump to solution

System: DH87MC motherboard - BIOS version 0047 - Win 7 / 64bit

Just bought a new monitor DELL P2851Q connected it via DisplayPort while the Win 7 was up and running

- installed everything including newest drivers - first in parallel to my previous PnP Monitor and it seemed to work fine.

When trying to boot with the new monitor switched on (both monitors or only the new one switched on)

the system stops during some BIOS check and I get a blinking cursor.

Only when connecting my old monitor switched on and the new one switched off

I get the message "BIOS has detected unsuccessful POST attemp... ....

or recent hardware changes ... Press 'Y' to enter Setup or 'N' to cancel and

attempt to boot with previous settings.

Entering 'N' since the new monitor is switche off anyway,

I can then boot with my old monitor and only after the BIOS has handed over to Windows

then its possible to power on the new monitor.

The new monitor will then be correctly identified by Win 7.

It may be an issue of my "old" BIOS 0047.

Reading the "Release Notes.pdf" of the latest BIOS

and the FAQ pages there was no indication of any problem like this

and I don't want to go for a trial an error approach installing a new BIOS.

Could you please comment whether there is a fix for this issue?

Fgmartin, this could be a BIOS issue since the current version is very old. This specific board has 7 newer BIOS, therefore I suggest you to update the BIOS but it will be better if you could install at least 3 versions before installing the latest one available.

Technically going straight to the latest BIOS version shouldn't be a problem, however based on experience, there is always a chance.

Please install the following versions

V152 https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=23454 https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=23454

V154 https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=23596 https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=23596

V155 https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=23821 https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=23821

Please let me know the model number of the processor you are using in order to provide you the latest graphics driver.

Thanks,

I will try the BIOS update to V152

The processor is an i5 4570 running at 3.2 GHz.

Just wanted to get this message out prior to the update.

The BIOS update to V152 solved the problem. The Dell P2815Q on DisplayPort is now recognized by the BIOS during the BOOT process!

Thanks for the adivice!

I just noticed one small bug even with the new BIOS V152: During BOOT procedure the hint for F2 to enter the BIOS (F7....etc) and the icon for the INTEL board does not display any more. I tried hitting F2 during the boot process but this did not provide the screen of the visual Bios only until I switched on my old monitor (still connected via the digital DVI port) I got the visual Bios screen. This is not a big issue for the time being sinde I can still connect another monitor if I want to change Bios settings but possibly this has already been addressed.

Thanks again

You may want to try installing the other BIOS in order to check if that solves this behavior.

Sorry to bother you again with a problem that might be related to the BIOS update (V154 is installed):

On the USB 3.0 I have been using a seagate backup drive. Switching on the Backup drive lately I got the message from Windows that I should format this drive. Since I got the same message for another USB 3.0 drive I tried it with the most recent USB driver (3.0.0.24) for the USB. Unfortunately this did not change anything. All USB 3.0 devices may only be operated using the USB 2.0 ports for the time being.

There are some newer BIOS versions that you can try. I suggest you to try may be version 155 first https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=23821 Intel® Download Center and if the issue persisted, please try 156 https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=23878 Intel® Download Center

Now the BIOS V156 is installed together with the USB extended Hub driver 3.0.2.54 (not the one listed for the DH87MC board being version 2. something).

The behaviour is somewhat better compared to V154

  • Win 7 detects the USB3.0 device for about 5-10 seconds
  • but then it breaks the connection again for about 5-10 seconds

This behaviour is cycling! The USB3.0 port cannot be used for those external Hard Drives for the time being.

As mentioned above for USB2.0 there is no such issue for me its clearly the 3.0 port behaviour.

Using the USB extended Hub driver 3.0.2.54 both Bios V157 and V158 behave quite the same:

  • Win 7 detects the USB3.0 device for about 5-10 seconds
  • but then it breaks the connection again for about 5-10 seconds

Again this is a cyclic behaviour and Windows suggests several times to format the external Hard Drive.

Using the USB Hub driver 2.1.5.28 which is the one suggested to be the latest for the DH87MC the behaviour changes a little bit:

  • Win 7 detects the USB3.0 device for about 5-10 seconds
  • but then it breaks the connection again for about 5-10 seconds

The behaviour is cyclic without any suggestion to format the drive. After about 10 cycles the drive is labelled as "Unknown Device" and Windows suggests to try to reconnect it. This unfortunately is not successful either.

Switching back to USB 2.0 the drive is identified immediately and Windows suggests to connect it to a USB 3.0 since the drive supports those higher data rates.
