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

llvmpipe means software rendering iirc
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.
Yes all pcie power connectors are 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.
Not modular. New one should be here by tomorrow
I’d try another cable, maybe dp instead of hdmi if that’s what you’re using. And make sure it’s plugged into the GPU itself. Maybe try different ports on the GPU as well. Good luck
Try limiting your PCIe speed to 3.0 (just for now) in the BIOS.
It’s a longshot for you, but I had similar issues when I tried to run PCIe too fast over a riser. It’s theoretically possible your motherboard is borked and can’t support the higher PCIe speed of the 9070.
ALSO, update your mobo BIOS!
Can’t emphasize this enough. If you’re having some weird hardware issue, try updating it.
According to fastfetch my GPU is “mesa llvmpipe”.
Assuming that this is Linux, I’d check
lspci, to cut software out of the question. If that can’t see it, then the kernel isn’t talking to the card.In general,
lshwis a good command to know. It’s not the most-efficient thing, but it’ll dump pretty much everything about your system to text that you can search through, without you needing to learn where the kernel puts information under /sys or the specific utilities that dump information about a subsystem.Do you have a Linux ISO or something you could boot into? I’m wondering if something in your display config is messed up seeing as you can SSH in
I could create one but I’d be trying to navigate the boot menu blindly. I don’t get my mobo splash screen or bios display when booting
I don’t get my mobo splash screen or bios display when booting
That already basically eliminates all possible software issues, so there’s no point in booting into a different OS.
550W is woefully inadequate for a 9070XT (and even your old 6700XT), though I doubt that’s the source of this problem as power consumption shouldn’t be all that high during boot / basic desktop use.
Does your 6700XT work consistently and reliably in this system? If so, the 9070XT is likely to be the issue.
Unfortunately, problems with computer components can often be intermittent.
In terms of symptoms, “no display” can manifest in a few different ways and a key differentiator is whether or not the monitor gets a signal. Some might display an OSD message that they aren’t receiving a signal. Some have a status indicator light that changes states depending on the presence of a signal. An LCD monitor staying on (main power / signal light on, backlight staying on) but on a blank black screen is often indicative of a defect in the graphics card (usually memory)
Others have offered speculation that there is something going on on with your software environment, I would expect you to at least see the motherboard manufacturer’s logo if that were the case.

I think people generally overestimate how much PSU they actually need, though.
Since I’m running a 3090 and a 32-core Threadripper, among other things, I picked a 1000W power supply. Reasonable enough.
But I also have it plugged into a UPS that shows current power usage, and the total input power of the PC is ~250W at idle, ~650W at full load, and I’ve never seen it go above 700W at all, ever. And that’s including accessories that aren’t going through the PSU at all. An 800W power supply would (in theory at least) be more than enough for even my ridiculously overbuilt and power-hungry system.
Maybe there’s something to be said for having an under-stressed PSU with significantly more capacity than you’ll ever use? It won’t have as much heat stress. Maybe it will run more efficiently at a lower percentage of its maximum load. If it for some reason loses some of its capacity over time, you’ll still have some wiggle room left. And, of course, it’s always nice to have a bigger PSU if you’re doing upgrades later, making it less likely that you’ll need to replace your PSU to do those upgrades. But still, I think a lot of home-built PCs out there are using a much bigger PSU than they actually need.
Plenty of folks do have their systems overbuilt - in fact, I see far more builds come through my shop with excessive power supplies rather than the opposite.
Power efficiency is a factor that varies based on model, rating, and load:
In this case, though, we’re talking about using a 550W power supply with a card that will readily use a little over 300W at load with occasional spikes that might reach as high as 400W. OP Probably has a fairly efficient CPU or maybe doesn’t have their card at 100%, but it is cutting things close and I’d expect this power supply to suffer excessive wear over time.
The 6700 was reliable back when I daily drove it worked fine when I tested it a few days ago.
The monitors seem like they’re trying to get a display (orange light turns white) but ultimately don’t get anything
I get the feeling that you have a failing 9070XT and that the symptoms are only presenting themselves intermittently.
When the card displayed at the shop, did they run any kind of 3D graphics workload / stress test?
They did not
Possibly your GPU is borked?
Did you buy it recently? Can you still return it?
I’ve been using it without issue since September-ish of last year, and it worked fine when taken to a pc shop
When did it stop working? Had you changed anything just before then?
Stopped working on Monday. Zero changes to anything since getting the GPU itself.
I was testing Minecraft with the new hardware ray tracing mod. It worked for a minute before the computer froze and for a split second I saw 100% GPU utilization in mangohud before it rebooted with no display
Hm… Yeah, unfortunately, that’s sounding more and more like a hardware failure.
Damn I had hope because it worked at the shop
Still, you’ll want to try all other possibilities before writing it off as a hardware failure. Because hardware failures are expensive, and other fixes are cheap or free.
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
