It doesn't matter how you have installed the windows, it could be also from USB but that's not the case!!!

Go to run and enter msinfo32, in the BIOS mode check if it is Legacy or UEFI, in order to work all GPUs as far as I know it should be UEFI, but in case it isn't I'm afraid of that you need to reinstall the windows, please check in youtube how to install in UEFI mode.

here in this threat there are some configuration settings - on page 7 here i wrote how to install windows in UEFI after you changed in BIOS to "UEFI only" (as you have to wipe the disk and convert to GPT first)

Dude you rock!!!!  That worked great!  Got 5 up and running.  Ran out of Sata ports on my psu so I can't plug the riser in and the last card. But that's ok, I'll use it on my next rig.

Thanks so much!
