Windows 10: win 10 Pro never starts first time, like something is asleep?

I really did not know what to put as a title because this issue is weird, to me anyway.
PC Specs are listed. The PC seems to be on, power light is lit steady, at first the monitor power light blinks like you would expect but then the screen just turns off? I shutdown (or use reset button) and this time all is well. Nearly everytime now.
I have searched the web. I did have my GTX 1060 6GB GPU in the 3rd pci e slot. Some mentioned it needs to be in one. So I moved it and reseated the power plug also. No change. I checked device manager for any signs (like with usb devices) was something telling display or GPU to turn off. Nothing.

I am stumped and pretty upset because this is a new build. I spent some bucks on this thing.
All ram tests are excellent. All benchmarks are fantastic,
Now I have never used HDMI for a display before because I never had a display that could take advantage of it, dispaly is a NEW Samsung 28" 3840 X 2160 UHD display..
Any ideas?
PSU is a NEW Antec Edge 750. I will add that I have had the edge 750 for about 2 years sitting in it's original box on a shelf in air conditioned BR. Was waiting for a new build to use it.
I also have the power for GPU plugged into the PSU in the suggested GPU rail according to Antec edge 750 docs.
Thanks and so sorry for the somewhat confusing info. But I am confused.

Windows 10 Won't Stay Asleep

Looks like there's an incompatibility with the drivers and the Creators update that you're using right now. May we suggest going back to your previous system build for now as it the only workaround we have for the issue right now. To do this, follow the
steps below:

• Open Settings window.
• Click Update and Security, Recovery.
• Select Get Started, under Go back.

No start screen in Windows 10 Pro

Although my machine seems to be using Windows 10 and was showing a Start Screen after download, I have now no start screen, no functionality with the search box, and my taskbar seldom auto-hides. I have tried the solutions suggested by community members,
but with no success. For example, I had no access to the AppXPackage.

I am using a Lenovo ThinkPad W510, Core i7, and upgraded from Win 7 Pro.

Can anyone suggest further steps I might take?

Thanks,

Rob
