Windows 10: No signal to monitor

About two weeks ago my computer wouldn’t wake up. The monitor remained blank. The keyboard did not light up. The desktop pc is on. I rebooted. Nothing. I unplugged overnight, restarted. Nothing. Checked all the connections. All good. Replaced the DP connection. Nothing. Replaced the graphics card with new. Nothing. Removed the ram and reinstalled. Nothing. Replaced the cmos battery. Nothing. Went through all the settings on the monitor. Nothing. Tried a hdmi cable. Nothing. Tried another monitor. Nothing. PC is about 2 years old. Hardware failure doesn’t seem to be the problem. Software seems

Windows 10 Update Installed & Now No Signal to Monitor

Hi,

For us to isolate your concern with your monitor's signal, we would like to know the following:

• When you say "signal", are you referring to the Internet?
• Are you getting any error messages? If yes, what is the exact error message?
• To make sure that we have not missed on anything, what troubleshooting steps have you done so far?

We look forward to your response.

 

Bizarre "No Signal" message on Monitor. Help would be appreciated.

Interesting. My mouse is Roccat Kova and yet when clicked device manager as you suggested above the "allow device to wake up computer" square is greyed out. But if I do it through HID Compliant Mouse it's already ticked. Both under keyboards (not sure why there are two) are ticked to allow waking PC from sleep. Other thing I noticed under DM is the monitor. Listed not as Acer but Generic PnP monitor and it's location is on NVIDIA GeForce. Is that right?

 

Monitor - No Input Signal

So you are suggesting that in the event this cable goes for a six, I try out the HDMI port? Seems quite a tenable suggestion - I never thought of that!
