Graphic card not detected or unplugged on Pavilion Gaming 15

[Ali1_0]

Hello,

I installed more RAM on my HP Pavilion gaming 15 yesterday but when I saw the task manager, my Nvidia RTX 3050 did not appear. I tried to launch a game but only the integrated graphics of my Ryzen 5 5600H is on. I opened the pc again but there is nothing looking wrong or cables unplug. 

(And my ram is detected, there was before 2 sticks of 4gigs and I removed one and installed a 16 gigs Crucial stick instead that working fine. So there are 20gigs of ram detected on the task manager)

Is this normal if I install RAM, or it can be repaired by switching something in the BIOS. Or I maybe unplugged something for the graphics card, and if it is, which cable is for the graphics card and how it should be because I see nothing unplugged.

UPDATE:
I went to the Device Manager and saw that my RTX 3050 is detected, so there's no connection problem. But when I see the graphics card properties, I see this message:

I've tried to update the drivers, but I get a message saying that they're already updated, but that I can still install new ones.

Do I have to install new drivers and if so, on the HP or Nvidia website? Or should I do something else to reactivate my GPU?

UPDATE 2 :

I've installed the drivers on the Nvidia website and the Device Manager tells me that the graphics card is working properly.

But it still doesn't show up on the task manager. I've tried uninstalling and reinstalling it and restarting the PC, but it still doesn't work.

What should I do?

UPDATE 3:
I restarted the PC and error 43 came back on the Device Manager.

I reinstalled the drivers but each time I restarted the error came back. I've tried installing old Nvidia drivers, installing out-of-date HP drivers and updating Windows, but the error persists as soon as I restart the computer. The Nvidia control panel doesn't light up and the graphics card isn't displayed on the Task Manager. The Nvidia application keeps asking me to install the drivers over and over again.
I've tried replacing the old RAM strip, but nothing has changed
What should I do?
