I think I already posted in a similar thread that you were also a part of, but I'll go ahead and pass on a few thoughts just in case it might help

1) Not sure if the 1030 needs the extra power cables or not, but if those aren't connected or have a loose connection on either end (the end that attaches to the card, or the end that attaches to the power distribution board), then it could be highly unstable or not even work at all, so that might be worth checking.
2) Might make sure the power distribution board is good if you have a way to test it. I saw somebody say that there was a problem with the older versions of the distribution board, so that might be worth checking.
3) i would think if you can't get into the bios, then your problem probably isn't with windows 10 directly, since I wouldn't think windows would have anything to do with things until *after* the f2 message disappears. So maybe something to do with power or bios related issues causing problems before that point.
4) if you have a way to test that video card in another machine to verify you didn't get a defective one, that might be a good idea.
5) it might be worth running a ram check. don't know why it'd be different with the card as opposed to without, but memory issues can be weird, so who knows?
6) with as tightly as things get packed into this case, you may want to verify that no wires are getting pushed into a place where they could block any of the fans. either on the card, or the power distribution board or front port (i assume all those are present). i don't know if it'd happen on an x51, but some boards will shut down right away if they sense a fan failure, and some systems might cause an overheat-shutdown before even getting past posting if some of the fans aren't cooling.
And on that note, you might want to make sure the video card's fan is actually spinning. stranger things have happened

That's about all i can think of for now. other that if you go to update the bios, do it with the working card in the system, cause lord knows you don't want a hiccup in the middle of a bios update;P
Anywho, take care and good luck!
