Question Display driver not detected - Nvidia

[STACKS ON DECK]

I have gtx660 on my windows 10 system, all of the sudden my display driver stopped working, in dxdiag, it shows “graphics device driver error code 43”. I have tried upgrading and downgrading the drivers but no use, it sometimes detect the driver but most of the time is doesn't. VRAM also showing 0 mb.
