Hey everyone,
I bought an
STGAubron prebuilt gaming PC
that was advertised as having a
GeForce RTX 3050 Ti M 8GB
and an
Intel Core i7 CPU
. It worked fine out of the box — games like
CS2, Elden Ring, F1 25, Valorant,
and
Overwatch
all ran smoothly on high settings.
But since day one, every time I tried to
update the NVIDIA driver
, it said:
"NVIDIA hardware not detected"
Recently I used
DDU (Display Driver Uninstaller)
to clean out old drivers before updating, and after that, the GPU disappeared completely. Now:
“NVIDIA hardware not detected.”
Device Manager only shows
Intel HD Graphics 4600
.
Task Manager has
no GPU section
at all.
NVIDIA driver installers say
“No compatible hardware found”
or
“Driver not compatible with your device.”
Reinstalling Windows (clean install, local reset) didn’t help.
BIOS shows something like “NVIDIA EFP5” but nothing else GPU-related.
I reseated the card physically and checked connections — fans spin, but it still isn’t recognized.
Hardware ID that was detected before:
PCI\VEN_10DE&DEV_25A0&SUBSYS_000010DE&REV_A1
That corresponds to a
GeForce RTX 3050 Ti Mobile
, but this is a desktop tower, not a laptop.
Specs listed online:
STGAubron Gaming PC
GeForce RTX 3050 Ti M 8GB
Intel Core i7-4770 @ 3.4 GHz
16 GB RAM
1 TB SSD
Windows 11 Home (clean reinstalled)
At this point, I’m not sure if:
The GPU is dead,
It was a fake/repurposed “mobile” GPU, or
It never actually had a real RTX card and was just using Intel integrated graphics.
What I’ve tried:
DDU in Safe Mode (multiple times)
Manual NVIDIA driver install (desktop and notebook versions)
INF install via Device Manager (no .inf files listed)
NVSlimmer to repackage driver
Full Windows reinstall (clean local reset)
Checked BIOS and reseated GPU
Verified power connectors and PCIe slot
Still only shows Intel HD 4600.
Current symptoms:
No GPU section in Task Manager
Device Manager only lists “Intel HD Graphics 4600”
NVIDIA drivers refuse to install
Games still
run
but clearly on integrated graphics now
What I’m asking:
How can I confirm 100% whether a real discrete GPU is installed or not?
Could this be a fake or nonfunctional RTX 3050 Ti?
Is there any way to restore GPU detection or flash firmware if it’s real?

If what little I'm finding online is true, the system came with a custom PCB with a repurposed 3050 ti mobile GPU, which is usually done when laptops are either torn apart to repurpose parts, or there was too much stock left of the 3050 ti mobile GPU.
I'm not really sure if you can just install the 3050 TI mobile driver and it will work, but you could try that. you may need a custom driver for that card, and I'm looking to see if it has one.
