Fixed windows 8 for me had all same issue.
For Windows Vista/7/8
a) Open an elevated command prompt as follows
For Vista/7 go to Start > All Programs > Accessories > right click on Command Prompt and choose Run as Administrator
For Windows 8 hover the mouse to the bottom left corner until you are seeing the Start pictogram > right click on it and choose Command Prompt (Admin)
b) In the command prompt window type the command below and press Enter
winmgmt /verifyrepository
c) You will get either one of these results:
WMI repository is consistent -no problems detected >> go to step f)
WMI repository is inconsistent -problems detected >> go to step d)
d) To rebuild the repository type the command below and hit Enter
winmgmt /salvagerepository
e) You will receive one of the results below
WMI repository is consistent -no problems detected >> go to step f)
WMIrepository salvage failed -failed to rebuild WMI repository. Try repeating step d) again.
WMIrepository has been salvaged - WMI repository has been successfully rebuilt. >> go to step g)
f) Reset the repository to its initial state using the command below and hit Enter
winmgmt /resetrepository
g) Now reboot the PC and check if the issue reoccurs
Hope it helps
