HP Probook 430 G1 - Intel HD Graphics 4400 - Code 43


New Member

I have just upgraded my laptop from Windows 8.0 to Microsoft Windows 8.1 Professional Edition (build 9600), 64-bit. However when I look in the device manager it says the following error next to the graphics device, "Windows has stopped this device because it has reported problems. (Code 43)". I can still continue to use my laptop, however cannot use the monitor and HDMI ports. I have tried the latest and beta drivers from the Intel site and I have also used the driver given on the HP support site for this laptop, but still no joy.

The current graphics driver version I have installed is

If I use the basic Microsoft driver the device just reboots after a random amount of 2-3 minutes.

Any suggestions? Could it be a driver conflict or hardware incompatibility?

Are there any logs I can provide or run any diagnostic utilities?

Thanks in advance.

Also I can see the dump files are gnerating the following

Bug check description: This indicates that a system thread generated an exception which the error handler did not catch.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: igdkmd64.sys (Intel Graphics Kernel Mode Driver, Intel Corporation).

I have managed to find a fix for this issue. I upgraded to Windows 10 (I am not sure I had to do this) but I tried this to see if this would fix the driver issue. However this still did not work. I then got a USB2UGA adaptor and downloaded and installed the drivers. I restarted the Laptop and both my HDMI and VGA ports started working. I also removed the USB2VGA adaptor and both ports are working. Hope this helps others. Would be good to know if someone can try this on Windows 8.1.
