Windows 10: Problem on Windows 10 Boot-Up.

Ever since switching to Windows 10, I can not boot-up properly.
Whenever i have a cold boot-up, I will get the Windows 10 insignia with loading circle. Then, I will get a black screen, and my screen will completely turn off and not detect my computer whatsoever. If i try to shutdown my computer, whether it be a single press or holding it, it will not do anything. I have to completely unplug my computer. What's weird is that once i try booting up after that, everything is normal (except it is a little bit slow.) I try to change the boot-up in msconfig, but it always resets itself to selective boot-up.
Thanks for the help in advance.

Also, I had Windows 7 before updating and it booted flawlessly.

Windows 10 Boot Up Problems

Start your System, then just after the Manufacturers logo disappears and Windows 10 tries to boot, press and hold the power button down for 5 - 10 seconds to perform a hard shut down

Do this Twice

On the third boot attempt, Windows will boot into the Windows 10 Repair Environment, from there you can access Startup Recovery, Safe Mode, Command Prompt . . . etc.

Go to Troubleshoot - Advanced Options - System Restore, see if you have a recent restore point you can revert to

If you do not have a recent restore point, go to Troubleshoot - Advanced Options - Startup Settings, click restart.

Upon restart press 4 to boot into Safe Mode, if you can get into Safe Mode, backup your data, reboot and see if your system boots normally

If all this fails go to Troubleshoot - Advanced Options - Reset this PC, choose to keep all your files and Apps

This will re-install Windows 10 whilst keeping your data and applications

 

If 're experienced enough with computers, can open up r PC and remove the dedicated graphics card then plug the monitor into r motherboard and try to boot? If don't have dedicated graphics or don't think that it would be a good idea for to mess with r computer, ignore this comment.

 

I have a custom built computer, so I can do that.

 

Connected using VGA directly to the motherboard. Flawless boot-up. It also seemed like the boot-up time was cut in half. I'm a little skeptical since it wasn't a cold boot-up, so I'll make sure to test it again in the morning.
Thank you for help.

 

r welcome! I was thinking that it had to do with the graphics card because there was no signal to the monitor at all.

 

Problem is still persisting. When i booted-up on the VGA connection, the screen was flashing a bunch of colors and then my computer yet again couldn't detect my monitor and i couldn't shut it off by the power button.
