Hey all I've been asked by one of our neighbours to have a look at a new to him pc he's recently built. He noted when he first built it he couldn't get any video out of the system but it seemed like it was booting into windows as he was able to use the caps lock light and ctrl+alt+delete wouldn't reboot the pc like it should if your stuck in a boot loop. Also the board he has all the post lights would go through their usual cycle and eventually turn off. He swapped the graphics card and still same issue so he asked us to have a look at it.
I hooked it up and at first couldn't fault it. Then all of a sudden it started doing the same thing. Boots, seems like it's in windows but you would never get video from the card. No bios splash screen. Np windows loading splash screen. No windows Lock Screen. Just black, the monitors backlight is on and it picks up a signal but no picture. I removed the graphics card and the pc booted fine several times. I put the GPU back in and again same issue black screen. I then put the GPU in our test system and it worked fine until loading superposition which immediately crashed then windows BSOD.
I Put the card back in the original system and it ran fine for several days, couldn't get it to fault again. Until last Friday. I was doing some research on this as I had the exact same issue on my watercooled 2080ti except reseating the hdmi cable would resolve the issue so o never looked further into it. I found a few guides and videos mentioning these symptoms and are usually memory corruption, but with those you should see the lights on the card turn off but with this one all the lights stay on permanently. I downloaded and ran mods anyway hoping it would find something but nope all that passed fine.
So long story short what else could be causing this? Just seems extremely weird how intermittent it is. Especially when the system boots perfectly without the GPU, so you would think it's a faulty GPU but our test system doesn't seem to like it. And we've tried both PCIE slots on the original board so it can't be a damaged PCIE slot either.
Is it worth trying to update the cards BIOS? It's a asus turbo 1080ti. I'm suspecting that may be the issue as when it was working last after booting into windows and just leaving it on the desktop doing nothing for a good 20 minutes or so the fan would suddenly go to 100% despite temps being low and the card being under zero load and this was the only consistent thing I could get the card to do so I'm thinking the bios maybe partially corrupted.
Thanks for the assistance.

I bought some stuff to try to repair it and learn as many things as possible about computer repairs but nothing worked so far. When the black screen appeared, my legion 5 pro was connected to my external monitor...
