Windows 10: Monitor cannot wake up from sleep but PC can

I just built a new system with Asus H370-F mobo, Gigabyte GTX1060 display, an old Dell monitor connected with DVI and newly installed windows 10. All mobo drivers are from Asus and the display driver is from Nvidia, all the latest. Power setting of all hardware and windows are default, except hibernation is disabled. The problem is after the system goes to sleep due to inactivity or explicitly click Sleep, moving the mouse or a key stroke will wake up the system (DVD drive blinking, HDD turning, power LED long on), but not the monitor. The only method to get the screen back is to press reset button. After this, it starts as if it is a reboot: i.e. POST screen (where I can enter BIOS), then windows loading screen, then logon screen. But then after logon, instead of a fresh windows logon session (as I can expected from a reboot), it resume the session before it sleep, i.e. all software that was running reappear. Hope somebody can tell me what is wrong.

Sleep / Wake Function, malfunctions after waking

Hi,

Issues that arise after waking up the PC from sleep mode might have been caused by a software conflict or system file corruption. For us to clarify the issue, we would like to ask these questions:

• What is the exact issue that you are experiencing?
• Did you notice any recent system changes prior to this issue?
• Have you encountered any error message?
• What troubleshooting steps have you done so far?

If you are having issues waking your PC from sleep, we suggest running the
Power troubleshooter as an initial troubleshooting. Kindly follow these steps:

• Click on Start.
• Type Troubleshoot, and then press Enter.
• Under Find and fix other problems, click on Power.
• Click on Run the troubleshooter button.
• Follow the onscreen guide.

We will wait for your response.

 

Using laptop as desktop - can't wake it from sleep with wireless mouse or keyboard.

• 4. Test waking from Sleep with the monitor connected to the laptop.
• 5. Disconnect the monitor from the laptop, reboot, then test waking from Sleep without an external monitor.

No luck with monitor connected. Disconnected the monitor, rebooted, then tested wake-from-sleep with no external monitor - no luck.

 

Monitor Not Waking Up After Sleep


I am experiencing a critical issue - when my computer goes into sleep mode, or if I manually place it in sleep mode, the monitor will not wake. The PC is running; I can hear the fan and the light on the front of the monitor is on, but the monitor itself will not wake. The only way I can get the computer back on is to do a hard reset by holding in the power button, turning it off, then back on. I've tried all the obvious fixes; windows updates, graphic card driver updates, unplugging, turning off sleep mode, turning off Link State Power Management ,making sure the keyboard or the mouse are able to wake the computer in settings, etc. Nothing so far has worked. Any suggestions on how to fix or what the problem may be?
An additional problem is that I cannot even save some new settings in my motherboard. Somehow the settings return to the default settings and the problem remains. The PC purchased brand new almost 4 months ago.

CPU Intel Core i5 8600k 3.60GHz
Graphic Card (integrated): Intel ® UHD Graphics 630
Motherboard: Gigabyte Z370 HD3
OS: WINDOWS 64 BIT

Could you please provide any suggestion?

I look forward to hearing from you.

Kind regards,
