I've recently upgraded my setup with a 5070 TI OC Vanguard GPU, but I'm facing a frustrating issue where it won't post through my ASUS Maximus XII Formula motherboard. I've checked a few troubleshooting steps: the PSU seems to provide adequate power, and I'm not seeing any connection issues with the motherboard. I even went through the RMA process for the GPU, and it came back confirmed to be working. This leads me to think the problem lies with the BIOS not properly communicating with the hardware. I'm trying to get it to recognize the GPU so I can install the necessary drivers, but I can't even access integrated graphics to attempt that either! I'm at a loss here—what else can I try to get my system to post?

Have you tried booting up your system without the 5070 TI installed? This can help confirm if the motherboard is functioning correctly. Sometimes, things work fine with an older GPU, which can narrow down the issue to the new one.
I faced a similar problem with a different GPU combo. I was able to get things working by booting with integrated graphics. From there, I updated the BIOS directly from USB. After updating, I disabled integrated graphics in the BIOS and forced it to use my new GPU. Turns out, the previous BIOS version was the culprit for the communication issue.
That sounds like something I might try! But I can't even get my integrated graphics to show up. I've checked and supposedly have the latest BIOS version. Is there a way to find an updated version if there's a newer one available?

Yes, I tested it with my old 2080, and it posts just fine without the 5070 TI.
