Alienware M15 R7 video_scheduler_internal_error, Video_TDR_Failure, Error 43 in device menager
I used my laptop as normal when one day it starter doing the BSOD, it would start lagging very hard and sound wound like get weird and after a couple seconds of it "crashing out" it would give me a BSOD with either Video_scheduler_internal_error or Video_TDR_Failure. After looking for a while I found that my dGPU coused the problem.
If I put any kind of preasure (like opening a game or even having a video playing) on the card (Nvidia geforce rtx 3070 ti) It would start to get weird and then crash my laptop. Sometimes when I turn it on after a crash it would seem like its ok but then if I look into device menager the dGPU shows as an ERROR 43 and doesnt turn on, also it has a code problem of 00000002B.
I did all of diagnostic check from bios and the dell support assist and they say my device is ok and "healthy"
I tried updating drivers and even uninstalling them and installing back with DDU tool on safe mode but that did nothing, even now when I go into nvidia app it shows I have available updates for gpu but then if I try to update it does one of two things. Crashes my laptop after a while of trying to update or updates but then still shows that same update is available
I have premium support and warranty so I contacted dell support but all they did is made me do a ton of fixes that did totaly nothing, also Im 90% sure im talking to an AI.
Support is telling me to do a OSRI recovery but Im certain that it wont do anything and I dont want to risk loosing my files since I dont really know or have a way right now to do a backup of my whole device
Pls help if you know a way to fix this or how to get support to do anything helpfull

Insist Dell send tech to replace GPU/motherboard under warranty—this is hardware failure, not software.

GameMode = ON
- Define each program to High-Performance GPU
HAGS = OFF
VBS = OFF
I suggest you then load MSI After-Burner, create this profile, and let it autoload. This is what I run on my (real desktop version) RTX-4080 and also my wife's RTX-3080 .
MSI-Afterburner for RTX-4080. Core-voltage +0 mV, Core +0mhz & Memory +0mkz (so basically, Stock-Clocks), 90% Power-Limit, 83c Temp-Limit, Auto-Fans with Sync
83c should be like 10c below TJMax of 93c. You really don't wanna burn-out or rough-up your GPU as that and everything else is soldered-into the motherboard and it will be expensive to replace (especially later).

@FlintCove I tried contacting support for the past 3 weeks or so but all the time I get AI replies telling me to format my pc even tho I told it its not possible couse my device isnt letting me (says there is no harddrive to install windows)
Now after a week my device isnt turning on anymore and just giving me the
BSOD with MACHINE_CHECK_EXCEPTION
So it looks like support was delaying the issue till my device is gone

@Mr.Rick ,
1. Sounds like it is "Turning On" aka Powering-On.
AFAICT, it's just not Booting-Up into Windows.
Trying tapping F12 around initial BIOS-Post (Dell Logo displaying). Run ePSA Diagnostics.
2. I don't care for AI-responses either, but AI or not ...
... sometimes the recommended steps are just the steps you (or someone) needs to follow to diagnose and/or repair the laptop.
