Look at your system crash reports for your CC 2014 crashes see if they point to where CC 2014 is crashing. The problems may be in your environment like a system device driver. You need to investigate the crashes.
Before reloading, I would try deleting the preferences. It may not help in this case, but it is worth a try.
In case you need help with that:
1) Close the program and press Ctrl+Alt+Shift/Cmd+Option+Shift during startup (not reversible)
2) Move the Folder. See:
Where would I find the crash reports?
The preferences thing that you suggest asks me about the scratch disk setup, and I don't know enough to start messing around with the scratch disks.
The second option you have linked to seems to be for resolving issues with illustrator, and I have tried to follow it but for photoshop and it's not the same; there aren't the same options.
Thanks for trying to help.
What Platform are you using?
It's a PC running Windows 7.
You did not manage to press and hold all three keys in time Shift+Alt+Ctrl Photoshop only caught the Ctrl+ALT so it asked about scratch disk instead of Preferences. Photoshop has three start up optional prompts invoked by the keyboard;
Shift - Dialog - Skip Loading Third Patty Plug-ins? Yes/No ?
Ctrl+Alt - Dialog that allows you to change your scratch disk settings.
Shift+Ctrl+Alt - Dialog - Delete the Adobe Photoshop Setting file ? Yes/No
I cannot find these so called "recovered files" to try and delete them to rectify the problem.
They should be on the drive assigned as your scratch disk in a folder called PSAutoRecover
Depends on on Platform and perhaps OS version. On a Windows 7 Pro system I find mine are in "C:\Users\User ID\AppData\Roaming\Adobe\Adobe Photoshop CC(for each version)\AutoRecover"
