BIOS fails to recognize the new GPU setup (ASRock AB350M-HDV with RTX 3060 Ti).
BIOS fails to recognize the new GPU setup (ASRock AB350M-HDV with RTX 3060 Ti).
I noticed unusual activity with the new GPU I acquired. It seems possible it might be connected to the motherboard as well. After initial use, I performed a CMOS reset just to confirm. The system started through CSM/Legacy and I followed the usual steps—restarting, adjusting BIOS settings, enabling PCI options (above 4G decoding), and turning off CSM/Legacy. Upon rebooting, the screen remained blank, not showing any post-boot content. After entering BIOS, the display appeared normally, but Windows failed to load. I reset CMOS again, then tried disabling only CSM to test. The issue persisted: no display during boot or in BIOS, and it only appears after Windows fully loads. I’m trying to determine if the problem stems from the GPU or the motherboard. For context, my previous GTX 1060 worked well with UEFI, while this motherboard (AB350M-HDV BIOS v7.30) shows similar behavior. CPU: Ryzen 5 5600; GPU: MSI RTX 3060 Ti; Monitor: HDMI; OS: Windows 10.
I'm confused about your question. Are you trying to explain why you want to use a legacy BIOS while booting with UEFI and also enable 4G? It seems like you're comparing performance between different storage types during the boot process. The post-screen issue is due to UEFI's faster boot times compared to older BIOS setups. Modern systems often combine UEFI with BIOS functionality through a compatibility module, but they still refer to it as BIOS for consistency. Your PC now launches much quicker than it did 20 years ago.
I really can't access the UEFI anymore after turning off the CSM—it just doesn’t show anything. When the CSM is off, there’s no display at all. I can only see it when the CSM is active. If I disable it, I have to use F2 to enter the UEFI, but even then it remains completely hidden. The only solution seems to be resetting the CMOS because the system defaults to that setting.
I understand how to start in UEFI without CSM enabled, worked on my GTX 1060, but with RTX 3060 Ti the screen doesn't show up and Windows isn't loading. The display remains empty.
