I am using Windows 10 operating system, and when I select shutdown, sleep or hibernate, the screen turns off but the PC is still in remains on and then it has to be manually powered off by pressing the power button for some time. I have even performed the System Maintenance troubleshooter, performed System and Security/Power troubleshooter, testing shutdown/sleep/hibernate in safe mode, no errors were reported. But in Safe mode reports an "unknown hard error". Kindly help me in fixing this problem!!!!
Thanks in advance.
