Windows 10: “No signal” on monitor every time I restart my PC?

So i’m currently in the beginning stages of an online Comptia A+ course which is cool, but I’m struggling because every time I shut off my pc and start it up the next day, I get absolutely no image at all and my monitor displays “no signal” and then shuts off after a couple seconds.

I’ve tried replacing the HDMI, I’ve taken apart and put back together pretty much everything inside the case and still nothing. Sometimes I can get it to work after unplugging everything, turning off mains power and then starting fresh, but this time it’s still not working?

If anyone has any ideas I’d be very grateful. I’d love to be able to fix it myself but I can’t even get far enough in my course to get the knowledge to fix it myself. It’s all kind of ironic and extremely infuriating, because this issue is preventing me from learning the stuff that would help me fix it.

thanks in advance to anyone who takes the time to help!

ps. apologies for bad formatting etc. I don’t really ever make reddit posts, and obviously i’m on mobile for above reasons haha

Monitor not receiving signal from pc after using hdmi passthrough

Hi,

Thank you for writing to Microsoft Community Forums.

HDMI Pass-Through does not work with all devices. Before attempting to set up an HDMI Pass-Through connection, you should make sure the source of the signal such as a Blu-ray player or Set Top Box, supports HDMI Pass-Through.

In order to get clarity on this issue and assist you with appropriate troubleshooting steps, please reply with the answers to the questions below.

1. Did you try a different HDMI cable to connect your PC to the monitor?
2. When you say "my pc will not display to my monitor", are you able to see any error message on it? For example: 'No signal'.

Meanwhile, try the below suggestions and check if this helps.

• If your monitor has an option in the Menu Button to switch the
  Input Source to HDMI Port, I would suggest you to try it.
• Try completely disconnecting your Xbox from the computer and just connect your computer to the monitor and check if you are able to see the display on the monitor.
• Make sure your display is plugged in and turned on.
• Unplug the video cable from both your display and PC, and then reconnect them firmly. After you reconnect the video cable, try moving your mouse on your display.
• Try connecting to different video outputs on your PC. Sometimes a change in driver can cause the video to be sent to a different display adapter or output.
• If you have your own display adapter installed and connected to your display,
  try connecting your display to the built-in video on the motherboard.
• Check for damaged HDMI cable, loose connections, or faulty adapters.

Hope it helps.

We're looking forward to your response.

Monitor not working - HDMI has no signal

Yesterday, my ASUS monitor was working fine connected to my HP spectrum using Windows 10. Today, the monitor delivers a no HDMI signal message. I have restarted both laptop and monitor, replaced the HDMI cable, updated display driver and still no luck.
Suggestions welcome.
