i have done all those things but video driver and touchpad driver isn't installing.

If you're able to see the drivers, right click on each one of them and select update. If anyway possible, please provide an image of device manager with Display adapters and Mice and other pointed devices expanded.

Type device manager onto [Cortana] search box, stroll down to Mice And Other Pointing devices and then expand it. Please check and see if Dell touchpad and PS / 2 Compatible Mouse are listed. Expand Display Adapters (Video) as well. Intel HD Graphics and nVIDIA Graphics driver should be listed.

Lastly,

Please type Windows Mobility Center onto the search box, and check if touchpad is turn on:

In my device manager there is ' microsoft basic display adapter' in display adapter and 'in mice and other pointing devices there is only ' HID -compliant mouse'

in windows mobility center there is no touchpad option found.
