Issue with sleep mode switching

pascal -  
Hello,

When I turn on my PC, it displays the message:
"Warning: Sleep mode switching" and then the screen goes black
and I can't do anything.

Thank you for your help

Configuration: Windows 7 / Internet Explorer 9.0

    Yes, it has happened to me at least three times too!!!

    I read online that it could be an overheating of the tower, but right now
    it's not too warm in my room
    there's not even heating and we're in October.

    Thank you in advance for your help!!!! ^^

    Have a nice day

      Hello.

      There must be a faulty device, unplug everything except the keyboard and

      the mouse, then restart to see, or try safe mode.
