Monitor won't turn on sometimes?

Question

Iron

Hello. Assembled PC:
Pentium g4600.
Asus h110m-r/c/si
Kingstom 2133 4gb
windows 7.
Monitor new dell 24'. I connect via hdmi to the motherboard. In general, everything works fine, but sometimes when the system asks to reboot, the PC reboots, but the monitor behaves as if the PC has turned off. That is, a message like flashes on the screen after 5 minutes, I’ll just go to sleep. At the same time, the PC is loading further, hdd is working and everything is spinning. How to diagnose a problem? By the way, it helps in this case to turn off the PSU on the system unit and distort the hdmi on the monitor to another socket.
