Have just upgraded my pc to a asrock pro4m z77 mobo and 2500k CPU. I'm using the onboard graphics only. I Installed win 7 pro 64bit today and having major issues.
I have two monitors, one connected by dvi and one using hdmi to dvi, but the pc only sees one and duplicates the screen with no option to extend.
Tried installing the drivers that come with the mobo and the system crashed, windows refused to load and had to restore to an earlier state. I tried using windows update to install the drivers and the same thing happened.
My windows performance score is 1 for graphics!
Tried looking in the bios and changing graphics from onboard to pice but it makes no difference.
Rest of system is m4 ssd, 8gb ripjaws ram, seasonic x660 psu.
The motherboard does support both dvi and hdmi, I tried unplugging a monitor and it made no difference!
I figured it out. You have to install service pack 1 before the intel graphics drivers. I was using windows update which was installing the driver first. Had to deselect it so it didn't install then install sp1. After that the driver installed with no issues!
