Recently, my laptop faced a black screen issue and shut down unexpectedly. When I turned it back on, it wouldn't connect to any monitors, even though those monitors work perfectly with other devices. Since then, I've been seeing Error 43 related to my GPU, and it's really affecting my gaming performance, especially in Marvel Rivals, even though my laptop specs should handle it just fine.
Here are my specs: AORUS Master 18 BYH, Intel(R) Core(TM) Ultra 9 275HX (24 CPUS), NVIDIA GeForce RTX 5080 Laptop GPU.

Error 43 usually indicates a hardware problem with the GPU, or it might be that it's not properly using the drivers. A clean install of Windows might help. Just make sure to delete the system partition when you do it—don't settle for a reset or refresh. After reinstalling Windows, let it set up the older default Nvidia drivers first before updating.
Error 43 can be triggered by either driver or hardware issues, including the GPU or, in some rare cases, the CPU. Since the easiest thing to change is the software, I suggest using DDU (Display Driver Uninstaller) to completely remove your current drivers and then doing a fresh install of the newest drivers afterward. If you’d like, I can guide you through the DDU process!
I followed a DDU guide and reinstalled my drivers, but I'm still getting Error 43 on my GPU.
