You need to determine which drivers are loaded and the characteristics about them.
Using a graphical user interface
Windows' device driver verification tool will trace the loading and activity of any device driver you choose. This tool is intended for developers and low-level system engineers, but it can tell you which drivers are or have been loaded during Windows operation and help you debug them in case you experience system or device crashes.
Details on the parameters, use, and results of the Driver Verifier Manager can be found in MS KB 244617, "How to Use Driver Verifier to Troubleshoot Windows Drivers."
