Display drivers error upon update

[aotten1986]

I have a Sony Vaio VGN FZ340E running Windows Vista.

Several weeks ago, I had an error occur with my display drivers. My laptop screen flickered black and would come back on. After turning the computer off and powering back up, I recieved an infamous blue screen that reported an error with nvlddmkm.sys. I booted in safe mode, uninstalled the drivers and rebooted with standard VGA display drivers. I have attempted to download and reinstall the drivers from Sony's website but every time I do, I still get the blue screen.

Long story short, I have been attempted to run a virus scan, Windows Defender and  Malwarebytes Anti-malware scan. All of those reported no issues. I did do a DriverSweeper scan of the NVidia drivers which found many errors. It was able to fix all but 3 files which it can't repair.

Does anyone have any ideas?

Well I tried those steps listed but when I went to delete the three files listed in that 4th post, only the first one was there. nvvsvc and nvlddmkm were not even in the drivers folder. Is there a reason that those two files were not even installed after just installing the drivers?

Did you go here - http://esupport.sony.com/US/perl/model-home.pl?mdl=VGNFZ340E&template_id=1&region_id=1&tab=download#/downloadTab and download/install all video driver updates?

Yes. I did all of those updates!

Can you try disabling Windows defender when installing the Nvidia drivers? You can install Microsoft Security Essentials which is more of the antivirus and antispyware protection for Microsoft.
