Question Asus TUF A15 dGPU suddenly vanished

[imhariiguess]

I am using a 2021 Asus TUF gaming A15 (FA506ICB) laptop with Ryzen 7 4800H and Nvidia RTX 3050 mobile platform. Windows 11 pro OS.

My issue began some two weeks ago, while playing CS2 (the only game I've been playing recently), either the game would crash or the entire laptop would restart. Sometimes I would see a BSOD with the VIDEO_SCHEDULER_INTERNAL_ERROR message.

To fix this, I tried rolling back to an earlier driver (from around June 2024 I believe) which I knew worked well. It didn't work. Then, I used the DDU tool and performed a clean reinstall of the driver, which fixed the crashing problem for about a week. Yesterday I encountered yet another blue screen, following which the game became completely unplayable (it would basically get stuck at the part where the title screen fades into the game menu). I then tried booting up PUBG and found out that it was really laggy as well.

Today I checked the task manager to see if the dGPU was activated at all and there wasn't one in the list. Just the AMD Radeon one (which showed high usage so I believe the iGPU was running the games).

What I've tried so far:-

• Searched the device manager. Would not show even after enabling the show hidden devices option. However, under the other devices section, there was a 'display' device, in the properties section it said that there were no drivers installed for the device. Location PCI bus 1, device 0 and function 0.
• Checked the BIOS. I think the BIOS is detecting it.
• Checked my Armoury Crate app. GPU mode was already set to standard, but I changed to Eco and then back anyway. Didn't work.
• Rebooted into safe mode to see if any third party app was doing something weird. Nope. GPU still invisible.

From the minidump folder, here are the last three dump files created by the crashes (sorted by latest first):-

1. https://www.mediafire.com/file/22a8zyqbsit9j9n/030725-25218-01.dmp/file

3. https://www.mediafire.com/file/zkijx16251uepd4/030625-24718-01.dmp/file

So I'm at my wits' end here. Can anyone help me out please? Thanks in advance.

Welcome to the forums, newcomer!

Yes, it's physically on your system. You're on the latest BIOS version for said laptop?

Use GPU-Z and see if you're able to see more than the APU listed in your list of GPU's on the laptop. This would also be a good idea to see if you're seeing any 0(zero)'s in the main window for GPU-Z. Very likely that the discrete GPU might've conked out. If so, there's nothing you can do to remedy it outside of RMA'ing the laptop.

When using DDU, run it in Safe Mode, remove all GPU drivers(intel, AMD and Nvidia) then manually install the latest GPU driver sourced from Nvidia's support site in an elevated command, i.e, Right click installer>Run as Administrator.

@Lutfij GPU-Z isn't detecting the Nvidia card, just the AMD one.. RMA also isn't an option cuz laptop is out of warranty. Will try using Linux from a USB drive and see if it detects it, if not then IDK what to do with this thing anymore..

If the dGPU is indeed defective, your options are:

1. Live with the issue and just use the iGPU
2. Replace the motherboard (available via a number of sources)
3. Replace the laptop

If defective, Linux won't detect it either.

Hello, sorry to bother again, but I ran Ubuntu on a stick and ran the ```lspci -vnn | grep VGA``` command which returned two GPUs. Also in the additional drivers tab of the Additional drivers app, I saw this.

Can I then, take it as a Windows issue rather than a dead GPU since Ubuntu can see it?

Thank you.

In Windows' Device Manager do you have any unknown devices indicated?

There is one NVidia platform controllers and framework under the software devices section. Nothing else.
