I have a computer who's sole purpose is to stress test different graphics card for resale. Sometimes, when it comes to certain older graphics cards, the mainboards 5 long beeps, pause a few seconds, then a short "good POST" beep, but the screen remains black. The HDD light flashes a lot so it's reading something, then the screen turns on when at desktop.
So far that I remember, I get this on 2 identical EVGA GeForce GTX 470 1.25GB graphics cards. I haven't gotten around to the EVGA GeForce GTX 580 1.5GB but I think it will have the same problem.
Does the Asrock Z370 absolutely require a GOP driver within the VBIOS to get a screen during POST?

Have you tried using a Vid card that does work, then go into BIOS and enable CSM compatibilty before trying one of those older Geforce cards. You can find it on the BOOT page. You may have to enable "addon rom display" (but unlikely as that is typically for add-on RAID cards with their own Boot BIOS but one never knows ;p).

Forgot to mention that under CSM compat. you probably will have to change the Video Oprom option to Legacy.
