Your best bet may be to get a different board. I've had issues like this before in my cryptomining days and motherboards can be very temperamental with detecting your card and automatically using it instead of trying to use onboard video. Sometimes it will just randomly work when you're messing with it.
It's total BS that the biostar board;
A. Doesn't detect your i3 and disable onboard video automatically
B. Won't just automatically detect and use PCI-E graphics, and
C. Has no utility to let you access the bios from within windows.
I would return the board to where you got it and get a different one, preferably one made by Asus or MSI. I remember a few years back hearing good things about biostar but as of lately they've really fallen behind compared to other manufacturers.
Also keep in mind that when you power cycle the system a bunch of times, windows may boot to the recovery menu rather than booting straight to your desktop, but you can't see what it's doing so you have no clue. Again, I go with a different board.
I'm sorry you can't get into windows anymore
