Good day, while playing earlier but PC got very unresponsive and I wait for minutes still not responding to my ALT CRTL DEL nor right clicks to refresh. I decided to reset it using the button but after the Windows Logo instead of going to Desktop it just went Black screen with cursor.

I tried pressing Shift key and ALT CTRL DEL but nothing. Also into Safe mode and start with CMD. Thanks

Specs: i5 4460

GPU: HD Radeon 6900 Series (But not inserted because some technician told me that my PSU cant supply it with enough power)
