if its still not working, then it will be a bunch of repetive questions about the following .
the chipset drivers for the motherboard need to the latest .
bios on the mobo also needs to be the latest.
same for the card if applicable.
latest version of win 10 preferably 1903 .
check with apollo and it runs in security l1
probably going to need and go ahead and place the relevant specs in the thread . (os version bios version card type and driver version and card bios version chipset version etc…)
also be sure that the bios has the pci slots running in 3.0 mode. and not 2.0
and of course make sure its hooked up right if applicable
