Does turning off »Use Graphics Processor« in the Performance Preferences (Photoshop > Preferences > Performance > Graphic Processor Settings) and restarting Photoshop have any bearing on the issue?
What have you done for trouble-shooting so far apart from reinstalling (and did you use the Cleaner Tool before doing that)?
Restoring Preferences after making sure all customized presets like Actions, Patterns, Brushes etc. have been saved might be a good starting point:
Oh yes ...
It works when I stop using graphics processor. But do I always need to turn off my graphics process for photoshop ??? It's not good for me because sometimes I need to do some have projects with lots of effects and filters. Then what to do?

My display driver is up to date
Did you check that directly from the graphics card manufacturer's site?
Don't rely on Windows to tell you if the driver is up to date. Windows is often wrong.
You can also try downloading a previous driver version.
