Shutdown from start menu does not work

[Violenn]

When i press shutdown at the start menu my pc does nothing. Even if i press it multiple times still nothing. The only way i can shut it down if my pressing the power button for some seconds or from the psu itself.

Which version of Windows do you have?

Run command prompt as an administrator and type in sfc /scannow

It will search for corrupt system files and then replace them. Should work
