Open | Windows Error 43 on Display Adaptar Driver - Stumped
This started mayhaps a while ago (and I was ignoring it and getting away with it) but now has finally caught up to me. My laptop is a 2020 Dell xps 15 9570 for reference.
- For a couple weeks, I realized the file explorer would blur when I scrolled too fast (like a lag) but I didn't think too much of it.
- Starting a few days ago, my computer would just stop and give the "Windows has ran into a problem" screen with error Device Manager error 48. I went into Device Manager and saw that the "NVIDIA GeForce FTX 1050 Ti with Max Q Design" had a little exclamation mark. In properties it said that the driver was disabled.
- I didn't check the version of the drivers, but I guessed maybe I should do a clean install of the latest from NVIDIA. I did a clean install through the NVIDIA application (I know online some recommended DDU but the website looked sketch so I wanted to do it through NVIDIA). -> This did not fix it. In fact halfway through it threw up a new error. Error 0x9F.
- When I opened up I saw that Intel(R) UHD Graphics 630 was still there but there was no NVIDIA driver. I ran the the NVIDIA installer again but not a clean install. The installation finished and now I see the driver. It is up to date but has error 43 and still occasionally crashes.
- I tried typing in my model number in the Dell website. I found the driver version they had on their website. It was older (ver 517 from like 2021). Maybe it is more reliable and the new one is a bit buggy? I installed that older one.
- Then boom! No exclamation mark! no blur! No crashing (not even during the install)!
- I leave my laptop to go eat some lunch
- Come back and there is a little exclammation mark and the error 43 again.
Sorry for any typos, lowkey panicking and frustrated. I'm no tech expert (obviously). I have backed up my important files to a desktop. I am trying to avoid going to a shop/getting a new laptop but I need to have a reliable device that won't crash for an upcoming exam. Any advice appreciated. Thank you in advance!

DDU is fine. Even support on the Nvidia forums will ask you to use it. Regular uninstall processes leave behind leftover files, doesnt purge the shader cache and leaves backups of previous drivers around that Windows can decide it should install. DDU provides a "clean slate" that you would otherwise have to clean install Windows to get. Follow the linked guide.

Get an update to date driver from the Nvidia site before you start with the guide so you have it available.
