Nvidia driver not detect

[Adityarizku]

I have lenovo b490 laptop. This laptop has nvidia 610m 1GB vram. But since i often switching my storage between ssd and hdd my  nvidia driver is not detected almost everytime i turn on my laptop. I dont know how to fix it. This problem started around 3months ago. I have tried many tutorials on google but it couldnt fix my problem. I brought my laptop to the best laptop service in my city but they cant handle it too.. Please someone help me...

 

sorry for my bad english. Im from indonesia

Have you tried installing the driver from nvidia's site? Going to the control panel and uninstalling the one that's on now and installing fresh? Checking the task manager to verify that it isn't running?
