Nvdia Graphics Drivers needs to Install after every reboot.

[svsourabhvaidya897]

Whenever I reboot my PC it works fine for 2 mins but after that it starts lagging and becomes very slow. I checked CPU and memory usage both are low. Cleared temp files etc.After some efforts I found temporary solution to reinstall my Nvdia graphics drivers.After reinstalling drivers PC works fine, even games run at 100 fps. But after I reboot my PC everything goes back to lagging. I checked in control panel that drivers are not getting uninstalled. Can anyone help please.
