Accidentally uninstalled Nvidia driver and Nvidia installer wont even find the hardware

[david.zero789]

I go a blue screen of death with the message nvlddkm.sys. I wanted to investigate the issue and started following a guide on how to update/reinstall the driver. (The guide: https://www.drivereasy.com/knowledge/nvlddmkm-sys-video_tdr_failure-blue-screen-error-solved-on-windows-10/ ). Since i'm really inexperienced with this kind of stuff, I tried my best to follow the guide step by step. I deleted the driver as the guide showed but I can't find nvlddmkm.sys in C:\Windows\System32\Drivers. I tried skipping the step, but the problem is the neither Nvdia driver, nor windows sees my GPU anymore hence I can't install the driver. I tried to do steps 5-9 but I get this message when trying to use cmd :
Windows PowerShell

PS C:\Windows\system32> expand.exe nvlddmkm.sy_ nvlddkm.sys
Microsoft (R) File Expansion Utility

Can't open input file: nvlddmkm.sy_.

I really don't know what to do and I'm terrified that i did something irreversible.

Download DDU, go to safe mode if you are using windows 7(Force restart PC and safe mode with networking), if windows 10 Shift+restart method,

After you get into safe mode, unpack DDU, run as admin, and clean+restart.
After that download latest (not automatic) select your windows, your GPU...

If it still doesnt wanna install, there is another way,
type device manager in start, select > arrow on Display adapters, it should show microsoft or basic, Right click it, Update, then Browse, then again browse and find the folder with unpacked Nvidia Drivers installer (when you unpacked it), and after that include subfolders and click next, and now it should start installing, after its complete restart system, if it still doesnt wanna ill try to help you further.
