Unable to see file names and some windows won't open.

Hello, my vista has been acting funny for quite some time now, and I'm coming

here for help.

Firstly, my desktop icons, folders, and files don't show their corresponding

names anymore, but only the date modified. I no longer have the option to

show the name of the file in the document settings. Also whenever I open the

personalize window from desktop it opens for a second and closes right away,

which is the second problem. There are a lot of windows that will open for a

second and close right away including personalize, games, search, windows

updater, etc.

Any help would be appreciated. Thanks.
