Hi, if you know the name of your chipset then you can get the correct drtivers from here: Drivers - Download NVIDIA Drivers

Microsoft also has an update/Hotfix for Intel M/Bs you can get it here :
Microsoft Download Center

Did you try and un-install the driver before you tried the new one? If so and your still getting problems, why not try a driver cleaner. You can download one for free here: Guru3D - Driver Sweeper

You could also try going into Device manager, right-click on the object and click properties. Here you can choose to either update or roll back the driver.

I hope that this is some help to you, please let me know if you need more help..
