If there is not display, then how will you install Video driver? It is not possible. As you mentioned, the login sound can be heard, then it might be the problem with LCD screen. Connect an external monitor if you have (press Fn+F4 to get the display on external monitor) and check if you are getting display. If display works on external, then the LCD is gone bad.
If no display on external too, then perform the following steps.
1. Disconnect the AC Adapter.
2. Remove the Battery.
3. Hold the Power button down for 30 seconds to 1 minute.
4. Reconnect the AC adapter and do NOT connect the battery now.
5. Turn on the Notebook power.
If the issue still same, contact the manufacturer.
