   hi , just got me a H470M-HVS motherboard , got it all set up windows 10 works fine , all drivers ect setup , i have no audio but most of all i have no option in bio advanced settings to disable onboard graphics , i used a gt710 nvidia and a gtx 1050ti both will not function right , main output is set to use the pci but both cards will either not show up or if i install drivers will show the error code 43 and say it stopped the drivers . any ideas on how to get me my gpu to work , the gt710 worked fine on my old mobo asrock and that was like an old ddr3 lol

	Fix Checklist Update BIOS to latest from ASRock site. Clear CMOS, then set BIOS: Primary GPU: PCIe Enable CSM (Legacy Mode) Use DDU to uninstall all NVIDIA drivers in Safe Mode. Reboot and install latest NVIDIA drivers. Check PSU (make sure it?�s at least 300??00W and has PCIe power if needed). If still Code 43: Test GPU in another PC. Try disabling onboard GPU in Device Manager (Windows). Audio: In BIOS, ensure Onboard HD Audio = Enabled. Install Realtek audio drivers from ASRock.
