Explorer and regedit crash!

[MR_MU53NDO]

i turned on my computer today, and i found that the first message i got was "Windows Explorer.exe has crashed" so i restarted explorer.exe and the same happened again. so i went and typed "regedit" into search, and when i clicked on the icon i got a message saying " the extended attributes are inconsistent". What do i do? please help
