Switched gpu’s now black screen?

[Noob1992]

Hey all, so I have a pc with a ryzen 7 5800x, tuff 570 mobo. And a gigabyte 3080 gpu. I bought and switched a zotac Trinity 3090oc into it. Nothing. Doesn’t even turn the monitor on. I’ve checked cables, monitor, and swapped back to 3080 and does just fine still. Shouldn’t need to download any drivers right? 3080-3090 swap should be fine I’d think. But maybe not? Especially since different brands? I’ve no clue. But I’m out a solid chunk of change if this gpu turns out to be faulty. Thank you for any advice or help! It’s worth noting that after I switched ports, several times, and powered the pc off and on several times, it did power up once and come on, I played a game on the 3090 for 2+ hours, before I went to bed and shut it off as normal. Next day, back to nothing.

1. Need PSU make and model.
2. When changing the GPU yes have to uninstall the old card driver first then install the new card drivers.

Can you access the system in safe mode?

Use DDU to remove the old drivers and then you can use the install media to install the new drivers.

It is 850w power supply. And if the screen stays black the entire time, how would I go about installing new drivers with the gpu inserted? Sorry to sound stupid, but I sort of am lol

And how would I get it to come on after messing with it, and play for hours, then go back to nothing? That’s what has me the most confused that it did work once for awhile.

1. Need PSU make and model.

I requested the make and model.

It is 850w power supply.

this is not a make and model. The information will be found on the PSU.

Would also suggest that you reseat the card and power.

Does the system produce any beep codes you may need to purchase a motherboard speaker since they no longer are attached.

Tye a different monitor, if more than one only one and or different ports on the card.

You state that

and swapped back to 3080 and does just fine still.

Is that still the case?

If so, use this card to uninstall the drivers install the new card and see if that helps having the driver ready to install.
