DriverView - Free - utility displays the list of all device drivers currently loaded on your system. For each driver in the list, additional useful information is displayed: load address of the driver, description, version, product name, company that created the driver, and more. Control Panel - Device Manager - Display Adapter - write down the make and complete model of your video adapter - double click - Driver's tab - write down the version info.

Always check in Device Manager - Drivers tab to be sure the version you are installing actually shows up. This is because some drivers rollback before the latest is installed sound drivers particularly do this so install a driver - reboot - check to be sure it is installed and repeat as needed. Manually look at manufacturer's sites for drivers - and Device Maker's sites. Hope this helps.
