Answer 1

Fair enough.  Something's changed on your system, then.
Things that can cause Photoshop to fail:
Newly installed 3rd party plug-in, but which is incompatible or has a problem.
Newly installed font.
Newly installed driver (e.g., for the display, by Windows Update).
Corrupted preferences.
You should know if you installed a plug-in or font, and if a driver update caused the problem you can usually get a better driver from the web site of the maker of your display adapter (video card).
To reset Photoshop's preferences to defaults, you can press and hold Control-Shift-Alt immediately after starting Photoshop from its menu entry or shortcut.  You have to be quick.  Keep in mind you'll have to reconfigure a lot of things again if you've changed them from defaults.
