I just had the exact thing happen with the same laptop... Except that PCIe controller says it can't start due to incomplete or damaged registry. Updating it did nothing and I couldn't see a way to repair it. I'm currently in the process of a full Windows reset. I just lost all my hard work setting this thing up the last month. If I could throw a rock through someone's window at Microsoft, I would.
*Update, the windows reset fixed it.
Today when i returned from work i restared my pc and i saw that bios was updateing i left it.... but after reboot i cannot see my NVIDIA RTX 2070 on my
The update i got it from windows update now my bios is 306
When i open Geforce experience its says that there is no nvidia card in the laptop its funny even...
Any help will be good thank you
Update 1 : i tryed with rolling back the 304 but still does not show the graphic card.
Update 2 : there is no problem with the bios update
Update 3 : I found out where is the problem : after the bios update you will get damaged PCI Express Root Complex in Device Manager something like that repair it or update the driver, then automaticly the geforce expirience will start working then start it update the geforce expirience then update the nvidia driver to the latest 441.12 by doing clean install on the latest driver then reboot the laptop and everything will start working without any kind of problem
