My ever terrible experience with this computer continues...

Due to some unfortunate circumstances, and one unnamed UK based PC part supplier, I have a new MoBo in my machine. Everything is working beautifully, but when I turn the machine on, I see the ASRock logo and the post screen, and the starting windows logo, but after that the screen goes blank and my monitor shows no signal? The computer boots through as I can hear log on noises, and can still use keyboard shortcuts to do things, just with no signal or output to the monitor. If I shut the machine down via the power button and switch on again, it will work then.

Would just like it to boot through cleanly on the first press of the button!

Can't think of what this could be and a google search isn't helping, so I thought I would ask you kind people for some advice! If you need any more info please let me know!

MoBo: ASRock Extreme Z77
GPU: MSI NVidia GTX 750 1GB GDDR5
Monitor: BenQ GL2450

I had the exact same thing happen to me and I would see the system post and I could get into the bios but after the windows boot logo the screen would go black. This happened after updating windows 10 to the latest build. If you shut the system down a couple times and then on the 3rd time it will boot into the windows repair diagnosing menu. Go into the advanced menu and select to restart in safe mode. For me it ended up being that windows would no longer display at 60hertz refresh rate in 4k. If I changed the refresh rate to 30 hertz it would show video in windows 10. I could use other resolutions and 60 hertz but not 4k for some reason. This only happened after updating windows 10 to the latest build.
