I've got a serious Lightroom problem at the moment that's really stressing me out as I've got a lot of work to get on with and I can't get it to run for more than 10 minutes at a time without crashing. It does it either flicking between images on the timeline or changing from Library to Develop.
I've tried completely re-installing, resetting preferences, signing out and back in etc. I've also tried turning off Graphics Acceleration BUT it crashes when I de-tick it so it won't turn off.
I've got deadlines to meet and this is really doing my head in - can anyone help?

I'm on the latest drivers, I think I'm going to have to wipe them and reinstall older versions one at a time to see if it makes any difference. The very fact that it crashes when I try to disable graphic acceleration is really p***ing me off though!
You can turn off 'Use Graphics Processor by editing the Preferences file in Notepad or other text editor with LR closed:
I see no benefit with my Nvidia Quadro 600 GPU and have it turned off in LR CC 2015.1 with no performance issues on my modest system (i7-860, 12 GB RAM, 256GB SSD, 2TB WD Black).
