Nvidia Drivers, missing on boot.

Korvanica

Hi All,

I have searched and googled this like mad and cannot find any answers or issues similar to what i'm having. (Maybe I just suck at googling)

For the last week i've been having a massive problem with my Nvidia Drivers.

Every time I boot my computer, it seems that the graphics drivers are either failing to start or just disappearing.
No errors show anywhere i've looked.
Firefox Crashed on startup, chrome will load, but will not open any pages.
Steam fails to start, as does Razer Synapse.(both of these are set to start on boot)

When I open the Nvidia Control Panel (which starts like normal) The Preview box is blank.

If I re-install the drivers, everything works fine again, (above image was post install, usally its just an empty box where the preview is)

Until I reboot my machine. Then its back to square one with nothing working untill i re-install.

I've tried reinstalling as admin & forcing a clean installation, neither of which worked.

Does anyone have any ideas

drivers getting corrupted after a boot could be a sign of a failing hard drive.

schedule a chkdsk on boot for your c drive and tick the check for bad sectors option
