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
Don't worry I intend to. I'm probably gonna take it back it to that shop and see if it miraculously still works there, and if it does, stress test it this time. The fact that the RGB and fans turn on is still a good sign at least
You should insist that they try different components in your own PC, one at a time, to find the cause. If they just power it on, it won't do you any good. A stress test would help, but still may not narrow it down to which component is faulty. It could be your PSU, motherboard, or GPU.
