Question Dell XPS 15 Graphics Card Problem

[TheMetalGearGucci]

I have owned my Dell XPS 15 9570 for two and a half years now, and it looks like it's nearing the end of its useful life. The battery's condition degraded drastically a few months ago, from its original 8 to 9 hours of charge to around 1.5 to 2 hours. It wasn't a big deal at first as I could simply get a replacement battery, but as the weeks went by, maintaining the laptop seemed to be a far more expensive endeavor. as greater hardware defects than I had anticipated began to surface.

After a night of screening a few episodes on my TV through the HDMI switch on the Dell, the laptop screen suddenly went offline and turned to black after unplugging the connection; but strangely the fan and backlit keyboard remained operational. This had only happened a few times in the previous years when I would wake up the laptop from sleep, and the only solution was to perform a power reset. I followed the same procedure here, but the machine launched into a boot loop instead.

Following several hours of fruitless troubleshooting, I determined that doing a fresh reinstall of Windows 10 on the system was the best course of action. I eventually got the system up and running, and the next step was to configure the NVIDIA graphics card drivers; unfortunately, each attempt to install them terminated in a blue screen of death (BSOD) owed to a failure on "nvlddmkm" (Stop code: PAGE FAULT IN NONPAGED AREA). I performed extensive diagnostic checks using the "Pre-boot diagnostics test" offered by DELL and received the following error codes separately:

• 2000-0511: Fan - The (Video Fan) fan failed to respond correctly.
• 2000-0333: Video - User provided no input for graphics test.

I think It's interesting to note that the HDMI connection between the laptop and an external display had been functioning flawlessly during all this until several days ago when it began periodically flickering to a black screen on the secondary display after my latest BIOS update. While doing some research on Google, it seems these issues could be owed to a dying GPU, however, neither of the diagnostic checks I ran indicated a fault with the GPU card itself - I'll share an image later. I am yet to disassemble the system since I suspect the fans require a thorough cleaning, but if It turns out this isn't the source of the issue, what is the next correct course of action I should take? Thank you for any responses in advance.

Replacement motherboard is usually the next step, though that would probably be very expensive since it was the top chip of its era. Though continuing to use the system with just the iGPU should be fine for most things.

Problem with thin and lights, they are thin and light. Not enough cooling, and if any one thing goes wrong, it is done.
