Nvidia has released a bug fix for its new software RTX 4090 And the RTX 4080 graphics cards Experience a black (or blank) screen on startup in some unfortunate cases.
This isn’t quite as bad as it seems at first, as the OS will still load fine and display your desktop on your screen as normal, in the end – you just get the blank screen on boot. However, this means that you cannot access the BIOS for example, or see anything at all on the screen, until you get to the operating system environment. And the inability to enter the BIOS can be a big problem in itself.
