Symptoms:

After installing Windows Vista, an error in Device Manager for the display adapter may appear with the error code 43.

Cause:

This error is caused by miscommunication between the motherboard chipset and the graphics card. This can be caused by using a motherboard that is incompatible or unsupported by Windows Vista. This issue can also be caused if the correct drivers are not installed for the motherboard after an OS upgrade from Windows XP.  

If the system contains an AGP motherboard with an unsupported chipset for Vista, the AGP card will operate in PCI mode only.  AMD's AGP adapters require correctly functioning AGP support from the operating system in order to run the WDDM driver under Vista. This WDDM driver has no way of working around the absence of AGP support.

Resolution:


To resolve this issue, first, ensure that your motherboard and full system are fully Vista compatible. For this you can visit the Microsoft Windows Vista Upgrade Advisor by clicking here.
If the motherboard is Windows Vista compatible, please visit the chipset manufacturer's website to download and install the updated chipset drivers for Windows Vista.
Other users have resolved this issue by updating their chipset drivers from the Device Manager. In the Device Manager, under the "System Devices" section, find the graphics controller (typically AGP to CPU controller or PCI Express Root Port), right click and choose update driver. Choose to connect to the internet or Windows Update to update the driver and continue through the update.

The following ATI chipsets are Windows Vista compatible:

  • ATI CrossFire™ Xpress 3200
  • ATI CrossFire™ Xpress 1600
  • ATI Radeon™ Xpress 1250
  • ATI Radeon™ Xpress 1100
