Acer TC-875 i5-10400 refurb, adding GPU, issues with Windows Activation

This was a total bear to get a GTX 650 1GB GDDR5 128-bit EVGA model card going with. I used a SATA to PCI-E power adapter, and a mini-HDMI to HDMI adapter, but I just couldn't seem to get POST or BIOS to appear using the GPU. (I would hear POST beep, and DEL would go into BIOS, F10 and ENTER would save and exit, but it wouldn't do much.)

Had to setup Win10 without the card, (left the 6-pin unplugged). Windows Update did load an Nvidia driver, and then I plugged in the 6-pin and restarted, and Windows 10 Lock Screen came up, eventually. But no POST or BIOS. I'm trying with a DVI to HDMI adapter from computers-hq, and I've got a 4K UHD display, but again, no BIOS or POST. There didn't appear to be any way to access the BIOS even using the onboard video, once card was installed and 6-pin connected, even plugged into one or the other HDMI outputs from the mobo.

I chalked it up to an anemic BIOS implementation, which was stuck on UEFI-only. (I did disable Secure Boot in my testing, to no avail.)

And I just discovered that Windows didn't Activate yet, even after being online for several hours and doing Windows Updates until "finished".

It's showing an actual key string, but saying that no key was present or something.

Hmm, I did flash the BIOS, using the BIOS downloaded from Acer, maybe the BIOS I downloaded doesn't agree with the Windows install pre-loaded on this unit? (Differences with refurb key?)

Whatever, it's certainly an annoyance if I want to sell the PC. I bought it from Acer Direct on ebay, so it's certainly a legit PC.
