Windows 10: Fresh install win 10 blank screen 1660Ti

I've been having issues with Windows loading up and getting a blank screen when Windows loads. Its been gong on for weeks on my Pc. But it works using the hdmi connection on my motherboard. But not my MSI gaming X 1660ti using the same connection. Everything worked well before the latest build of windows. 20H2. So I performed a wipe of my pc. And everything worked well with it plugged into my Gpu until Windows loaded and the settings started changing as it was installing things automatically. The display dimensions changed as it was running for the first time which I guess was it configuring

Fresh Install of Win 10 without Serial Key?

Looking to reformat a laptops HDD, and then reinstall Win 10 fresh. The problem is it came pre-installed with Win 8 and I did the free upgrade to Win 10. How exactly would I re-format the HDD, reinstall Win 10 and ensure it reactivates properly? I don't see a Win 8 serial key anywhere in the contents of the box.

 

Win 10 blank screen

Win 10 downloaded & converted cleanly. It worked cleanly for 2 days on a Dell laptop - Inspiron 15z (5523, Late 2012). Decided to do a clean install to clear out residual history stuff. Made backup copies of my files. Initiated the creation of the
recovery/restore USB. "When it finished I clicked on file explorer and the screen went blank. Only the cursor remained. Nothing would change the screen but the cursor would respond properly.

Powered off and powered on and got to the sign on page. Enter password and got welcome screen with circling dots. When this process turned control over to desktop the screen goes blank but shows cursor. Tried key combinations (Fn, windows, etc,) and only
the CTL-ALT-Del combo worked which brought up task mgr. All systems were go according to Task mgr. Could start and stop processes. Also enable and disable them. Trying to see the storage location or other function gave me an "not found" error msg.
Could use the network and power buttons properly in task mgr. So the hardware was working and the drivers too. Windows 10 is running but does not display on the screen. Win 10 is running in idle mode.

Tried to use alternate boot up which gives the windows logo and then goes to the blank screen with cursor. Hardware diagnostics are fine and pass the tests. The majority of advice in the "community" require visual access to recovery steps or restore steps.
How to get that done?

Suggestions?

 

Fresh USB Windows 10 Install - Failing

I am trying to install a fresh copy (reformatted the hard disk) of windows 10 using a USB

• Created an installation media on a USB flash drive (Win 10 pro) from this page https://www.microsoft.com/en-us/software-download/windows10
• Changed the boot order on the other PC so that it boots using USB
• Selected custom install
• Installing Windows goes through the following steps successfully: Copying Windows Files, Getting Files ready for installation, Installing features, Installing updates and before the last step (Finishing up), it restarts
• Then it goes back to the start of the installation steps

I am stuck and have read numerous posts but don't know what to do to install a fresh copy of Win 10.
