What is seen on your monitor is not necessarily what is happening in the PC. To try another monitor seems a reasonable idea to me. Indeed I would try the monitor in another PC if you can get access. It's got to be worth a try. At least it would eliminate the monitor.

@mitchell65 Results of replacement tests are inconclusive due to the unpredictable nature of the problem. I've done that. I will do that again. At the moment, I want to focus on the onboard graphics card. Is there any way I can check the health of my onboard graphics card?

I had similar problems with my desktop PC and my Iiyama monitor 3 years ago. I first thought it was my GeForce GT 730 graphics card:

- removed the 730, blew out the tiny amount of dust, refitted and switched to onboard graphics:

- same problem. Then I bought a DVI cable and used that instead, it worked. Tried the VGA cable in another PC on another monitor:

- produced similar problems on that PC. Tried another, known good, VGA cable on my monitor and my PC:

- same problems.

CONCLUSION: my monitor has a shafted VGA socket. Still working fine with a DVI cable connection today.

Are you saying that when you plug in a different monitor and a different cable the same problem exists?
THe only way I know to check the onboard graphics is to fit a second graphics card in the PC. Plug the monitor into that card and it will automatrically bypass the onboard graphics!

@Bertison That is not an option for me.

Understood Manojit. You have no DVI input on your monitor. Apologies: sorry, I have no further ideas.

Hi,
Personally I stopped dual booting on the same drive as another os it is just too problematic or at least for me
I use one of these to swap out different os's it has made life so much more straight forward especially when win-10 and linux is involved

If a monitor goes into sleep mode it senses no activity as you probably already know
What is causing it there is no telling :/

Have you tried safe mode with networking ?
