Sorry if there’s a better community to put this in.

Basically title, I have a 9070xt and whenever I turn my PC on, the GPU turns on (RGB and fans), but I don’t get any post or display to either of my two monitors. I only know the rest of the PC is working because I can ssh in. According to fastfetch my GPU is “mesa llvmpipe”. After taking the 9070 out and putting my old 6700xt in, everything seemed to work fine.

I brought it to a PC shop just to see if everything still worked. The 9070 worked in their machine, and it also worked when they put it back into mine. I didn’t touch anything, brought it back home, and now it’s back to it’s previous behavior.

I already have a new psu on the way (550w made sense when I first put the system together) but I’m not actually sure it’s causing my current problem because it worked at the PC shop.

Any help or insight would be appreciated and I can update with more information if required

    Just to be sure, all power cables are plugged into the GPU right?

    Some work without all of them, some work with none of them. But most GPUs need all pcie power cables to be plugged in. Some GPUs have lights to indicate if there’s a power cable missing/not fully plugged in.

        Do you have a modular power supply? Might be worth swapping the PSU PCI cables with different ones if so, also changing the ports they’re plugged into on the PSU side to really make sure it’s not the PSU. I’m surprised that the shop you took it to didn’t do something like swapping only the power supply, for example.
