Question Trying to upgrade GPU on a pre-built

[Chuck7461]

I have a pre-built Asus G15 ROG Strix Desktop 8-Core i7-11700F 32GB RAM 512GB SSD I bought it in2021 without a GPU and I put in an older EVGA GeForce GT 740 4GB.

So i am trying to do a i minor GPU upgrade with a New ASRock intel ARC A380. (Its called a Challenger ITX) My problem is when ever I install the new GPU , My PC will not boot, it just sits there dead in the water and never even gets to the BIOS. I have made certain that I have installed the GPU so that it is totally seated in the slot.

Curious if anyone can assist with this one. I have loaded my old GPU and everything comes right up. I will test the new GPU on another pc later and report back. Thanks in Advance for any assistance.

What are the specs on that power supply.

Thanks for asking... I see the writing on the power supply
Great Wall 80 plus Gold E750

750w should be enough? I think?

PSU is good quality, and overkill for any GPU of this realm.

When the system doesn't 'boot' - what happens when you press the power button? Does it immediately shut off? Or do you need to hold the button down to shut it ofF?

Just checking - but you *are* connected to the GPU's output (HDMI or DP) and not the motherboard?

Did you remove the old Nvidia drivers prior to installing the Intel GPU?
