Question New PC won’t POST with 3070 Ti GPU installed, but same GPU works on other computers ?

[Ellllias]

I built a new pc today, the only parts that remained the same from my old computer are my GPU, SSD, and Hard Drive. For some reason whenever my gpu is plugged in the computer cant move past the VGA stage of post. The computer can however boot from the IGpu if the gpu isn't plugged in.

Here are things I have tried:

• Disabling and enabling EXPO
• Disabling and enabling Fast Boot'
• Disabling and enabling Secure Boot
• Disabling and enabling Native ASPM
• Switching gpu to the other PCIE slot
• Trying to post without any drives in and just one stick of ram
• Removing the CMOS battery for 5 minutes
• Tested that gpu posted in another system (it did)
• Bought a new PSU
• Switch default graphics device in BIOS to the IGpu (this made the yellow boot light turn on, but never actually posts)
• Set the PCIE slot to PCIE 3 in BIOS (Same yellow light issue)

BIOS Version 3067 x64 (have not tried other versions - I dont have a USB drive to install it onto and this is the latest stable build)

Old specs:
I5 10600k, Asus Prime B550M Motherboard, 750W Seasonic FOCUS PSU, 24Gb of Corsair vengeance ram, and a gigabyte 3070ti GAMING OC

New specs:
Ryzen 7 9700x, Asus TUF Gaming B650-E, and 32Gb of Kingston Fury 6000Mhz DDR5 Ram, Thermaltake Toughpower 850W Psu, gigabyte 3070ti GAMING OC

According to ASUS support they can’t help because the GPU isn’t on the officially supported list for their motherboard, but it’s 2024, and I don’t believe that’s the problem.

Is there any other steps I can take to troubleshoot myself?

I just want to Thankyou for all your help today, it’s been hours and I know you don’t get anything out of it, but I super appreciate it.

no problem its a hobby of mine and i build pcs so any pcs i can fix threw diagnosis is a win. honestly i suspect its the motherboard at this point. which doesnt shock me as im seeing alot of issues with am5 boards from asus not playing nice with nvidia.

If the problem is a possible compatibility issue if it would make sense I’d be willing to sell the card and switch to a 7700xt or a 7800xt, because the store I bought the pieces from is quoting $110-$150CAD to diagnose, and if it could be solved by just buying an AMD card it would be a similar cost. Does that make sense or should I just pay them to diagnose it then RMA if needed/switch card after if needed?

I personally would just switch out the motherboard for a gigabyte version. I find there more reliable.

Ok. I’m thinking I’ll pickup a Gigabyte B650 Aorus Elite AX because it’s $30 off and does officially support my memory. Ill just have to try to sell the ASUS board and bite the loss.
