Question Black screen after waking up PC ?

[black97 devil]

Hello

the PC shows black screen after waking it up with mouse --- i noticed that the LED lights of the mouse and keyboard are turned off while this happens- , then its restarts by itself and the black screen happens again .

Note that this problem happens only after long sleep (hours ), sleep and wake immediately works fine.

This problem happened to me before so I changed a lot of settings then it worked , but unfortunately I don't remember which settings.

I tried literally everything:

• change power plan
• turn off fast boot
• hibernation
• sfc /scannow
• power troubleshoot

no luck

i noticed that the problem appear only when external HDD connected (i have 4 of them) ,
