Solved Monitor no signal from CPU and power button keep Flashing no display

There is no signal to the monitor and all lights and fans work fine and Only black screen with the blinking or flashing power button.
Still doesn’t work?


Can you try to:
1. Boot into the BIOS by continuously tapping F1 on startup
2. In the BIOS, navigate to the Power Tab set the following settings:
ACPI Standby Mode – S3(STR)
After Power Loss – Last State
3. Press F10 to save and exit BIOS
Adjust the sleep timer to 1min and test the new settings.
in Windows, can you try to hold the shift key and click Shutdown then try to boot into the BIOS  by pressing F1. If that doesn’t work, try to disable hybrid shutdown then try again.
