Windows 10 commonly boots to a black screen with no cursor?

Yeah, just registered with Ten Forums and all that good stuff, and so here's my first of possibly many issues I shall bring to you. xD I upgraded my preview build of Windows 10 (10130) to the pro final version because the preview wasn't able to find additional builds and kept crapping out on standard updates. All went smoothly, but the first thing I noticed is that the next time I booted cold, Windows 10 would get past the "starting windows" screen and play the startup sound. However, the logon interface never appeared, or the cursor. All that was displayed was a solid black screen. I hard reset by holding down the power button and tried it again, which gave me the same thing. Again, hard reset. This still commonly happens, along with my CMOS date/time settings apparently being wiped after such reset. Sometimes the cursor appears, but mostly it doesn't. Usually after trying enough times it'll pull through or by starting it after selecting a recovery option from F8. "Enable low resolution video" I know worked before, but it didn't give me low res display. (Not that I'm complaining) It could likely be because I installed over the preview, and in-place installations typically have issues. I'm also running a program to provide titlebars with aero styled glass transparency, and my graphics driver is up to date. Any thoughts...?

I had installed the Technical Preview on a partition that was separate from Windows 7. I had started with build 9926. In that case I could boot either 7 or 10 TP in a dual boot.

My build was activated. Unless that's not what's you're talking about.

Pretty much as soon as a new build released, (I set myself to fast ring) I waited a few days and then updated to it. But when was 10130 supposed to expire? I don't think it was then, because I wasn't getting shut down every so many hours or features reduced. I upgraded to RTM this August, 8/8 to be exact. (Thank you systeminfo CMD command) I tried the reset PC option (in order to function with my new motherboard) and it still occurred. The only others are to use an image or system restore, which if it's been going on since I went to RTM, that wouldn't help either. The preview didn't have this issue. If I went into safe mode, what would you want me to try? Or just see if it boots without a black screen?

I had kept the preview after replacing the board, (from Intel to AMD chipset) but then upgraded it to RTM. that's when I noticed the the black screen and CMOS issue. I reinstalled 7 on top of itself so I wouldn't keep getting blue screens. (Frustratingly, a mobo driver is the only one that isn't easily replaced) ^^;
