Windows 10: Why won't my computer open any programs after i close a game?

I have recently been having problems with my pc not opening anything and freezing after I close any Games. I am not sure what is causing it but i recently had an AIO fail on me and my PC was at 105 Celsius for an unknown amount of time but so far it starts up and runs fine with chrome and other applications. But after I close any games my rig just poops out.

Windows 10 won´t start any program as Administrator

Hello. I´m having this issue since installed one of the latest Windows 10 system updates.

When I try to open any program that requires Administrator confirmation (that screen with the Yes/No question), this dialog won´t appear anymore. The screen background stays darkened and nothing happens.

1. Using Windows 10 Home (x64)
2. My microsoft user account is properly checked
3. I´m the administrator of the PC
4. Already tried do create another administrator user account - same problem, no success
5. Cannot start any program/service that requires administrator authorization (not even regedit)

Please help!
