nVidia Driver Crash

Can you install the latest Driver and check if it will still crash?

look also in event viewer fo errors; they may show you what's wrong

Make sure all your Windows updates are done as well as video driver. Update BIOS and Chipset as well.

Is the machine restarting? or is the screen going black and coming back?  I had the latter issue several months back. The error was infrequent (every other month) and has gone away as updates have been done. The machine never crashed and I never lost anything.

screen goes black then comes back ,


?

Yes I have seen that. How often does this happen?  

For me it was infrequent and has gone away with updates.

Try reinstalling or repairing the Video driver (as suggested above) but be sure to get BIOS and Chipset updates first.

Did you try my solution?

any errors in event viewer?

I noticed this happens sometimes when Outlook is opened , and also saw this on the bottom right :
Windows Kernel Mode Driver
.........???
