New PC build for brand new (7800x3d,4090) with no HDMI output on first start-up
I recently assembled a brand new 7800x3d,4090 pc build. All components were installed correctly and I double-checked everything. The system started up normally, fans were running, and both motherboard and GPU lights lit up. The TV displayed "checking the device connected to HDMI 1" which disappeared after about ten seconds, returning to its previous state without a signal.
I tested various setups: HDMI connected to the 4090 GPU, using the integrated MBOO graphics HDMI, a different TV, another HDMI cable, and even rebooted multiple times. I disconnected and reconnected all cables, ensured everything was properly seated, and checked the components again.
I also tried connecting the keyboard and pressing F2, then using the DEL key, but no display appeared. My guess is it needs to enter BIOS for proper display, though I’m not sure. Anyone have any suggestions? Thanks for your help.
i'm not clear on your request, are you asking how to create a completely new bio from scratch?
With the CMOS button located on the back of the motherboard, you can access the BIOS. Have you verified your motherboard's BIOS settings? It seems you might need an update if it doesn't support 3.10 BIOS. '1. Updated to AMD AGESA PI 1.2.0.2a for next gen Ryzen X3D CPU performance optimized.'
