Go here detect the correct CHIPSET you have and then try to upgrade the DISPLAY driver..
Then run the automatice detect drivers and if any update available - install it...and see if the YELLOW triangle under DEVICE Manager for Intel Interface goes or not?
In the device manager, the system device "Intel(R) Management Engine Interface" is marked yellow with the message "The device could not be started. (Code 10)"
A third symptom is, that the hardware monitor in the Intel Desktop Utilities (V3.1) only shows data about the harddrives, nothing else. Before it showed the processor and motherboard temperatures, fan speeds.
I realise this post is from nearly a year ago so you may have sorted things out by now but both of these problems arise when the Intel ME driver is not installed. For the 4 Series motherboards (specifically the DG45ID), the latest Intel ME: Management Engine driver is here: http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=16081&lang=eng if this is downloaded and installed see what difference you get and post back. You should also clear all the error logs in your BIOS as that'll be taking up valuable memory. Test things with no cards plugged into the motherboard and see if you still get the BIOS error log entry.
