If so, what makes you think that it is the video driver? Have you worked through the other options first?
If you want to update the video driver, go to click here - just follow the download links, and you will get the right driver.
It is equally possible (in terms of suspect drivers) that you might need updated drivers for the motherboard - they should be available from the manufacturer's web site.
For now, try booting into Safe Mode and looking in Device Manager for any error messages - that should give you a good clue with regard to missing or faulty drivers.
As a general point, trying to troubleshoot by making 'inspired guesses' is always the longest, hardest method. Starting at one end of the problem, and eliminating possible faults in a logical sequence, is always the quickest and most effective way.
I will take your advice, but I will save all this advice and wait until this evening when the "expert" arrives. I have no hardware device conflicts in Device manager, and I've downloaded a 13MB file from Nvidia. My partner will no doubt know what to do, and two minds are better than one.
I reckon this site is quite useful.
