Welcome to Motherboards.org!
The driver set must be intended for the specific feature model. If a driver disk came with the mobo, use the driver set from that. The driver set is critical so that the OS knows what each feature is, and how to work with it.
Not only video, but bus interaction and power resources.. plus other devices.
If you had no driver disk for the mobo, then get a diagnostics program such as Everest Ultimate Diagnostics from www.lavalys.com/
which is not expensive. There is a free trial version, but some features are locked out. Another program is PC Wizard from http://pc-wizard-2008.en.softonic.com/
which is freeware, but the authors would appreciate a donation to keep it so.
Either program will display all the "secrets" of your system.. and provide BIOS data and also links to drivers for hardware.
When first powering up the system, note the lower left-hand corner of the screen.. there will be a long string of characters there. This is the BIOS string, a positive ID of the mobo. Copy that string, and Google it for links to drivers/manuals.
F@H.. to solve mankind's maladies.. in our lifetimes!
