White screen

[Nicole]

Hi Brian. :-)

My husband’s laptop has a white screen after start up. Apparently he did an update last night.  It will start up okay and ask for the password to log in then nothing but a white screen .  Any advice?

Thanks

Don’t worry, I think I’ve fixed it. 

I googled like a mad woman, fumbled my way through a whole heap of crap. Somehow I ended up in the the disk Utility screen and hit first aid on everything and restarted. 

I got lucky and I know it! Lol

Botched up video driver. You did what I would do. Glad it's sorted out. Now, when was your last Time Machine backup done?
