The Asus TUF A15 dGPU disappeared unexpectedly.
The Asus TUF A15 dGPU disappeared unexpectedly.
I am working with a 2021 Asus TUF gaming A15 (FA506ICB) laptop equipped with a Ryzen 7 4800H processor and Nvidia RTX 3050 mobile platform, running Windows 11 Pro.
My problem started about two weeks ago while playing CS2; the game would crash or the whole system would restart. Occasionally, I encountered a BSOD displaying the VIDEO_SCHEDULER_INTERNAL_ERROR message.
To resolve it, I attempted to roll back to an older driver (believing it was effective around June 2024), but that didn’t help. Then I used the DDU tool and performed a clean driver reinstall, which resolved the crashing issue for roughly a week. Recently, I faced another blue screen, after which the game became unresponsive—typically freezing at the title screen transition into the game menu. I also tried launching PUBG, which was very slow.
I checked the Task Manager to see if the dGPU was active, but it wasn’t listed. Only the AMD Radeon was present, with high usage indicating the iGPU was running games.
My attempts so far:
- Searched the Device Manager; it didn’t appear even after enabling hidden devices. However, under the Devices section, a 'display' device was listed, properties showed no drivers installed (Location: PCI bus 1, device 0, function 0).
- Verified BIOS settings.
- Used Armoury Crate app; GPU mode was set to standard, then changed to Eco and back—no improvement.
- Rebooted into Safe Mode to check for unusual activity from third-party apps; no issues found.

I’m at a loss and would appreciate any guidance. Thank you ahead of time.
Welcome to the forums, newcomer!
Reviewed the BIOS settings.
It seems the BIOS is recognizing it.
Yes, your system has the latest BIOS for this laptop?
Use GPU-Z to check if it displays a GPU beyond what's listed in the laptop's GPU list. Also, look for any zero values in the main window of GPU-Z.
It’s likely the discrete GPU has failed.
If that’s the case, you won’t be able to fix it except through an RMA process.
When using DDU, start it in Safe Mode, uninstall all GPU drivers (Intel, AMD, Nvidia), then install the newest driver from Nvidia's support site via an elevated command—right-click the installer and select Run as Administrator.
GPU-Z isn't recognizing the Nvidia card, only the AMD one. The return policy also doesn't apply since the laptop is out of warranty. I'll attempt to use Linux from a USB drive and check for detection; if that fails, I'm unsure what to do next.
Hello, sorry to bother again, but I installed Ubuntu on a stick and executed the ```lspci -vnn | grep VGA``` command which displayed two GPUs. Also in the additional drivers section of the Additional drivers app, I noticed this. Can I then treat it as a Windows problem instead of a dead GPU because Ubuntu can recognize it? Thank you.
Yes, the Device Manager in Windows shows any unrecognized devices that are detected.
Under the software devices section, there is only one NVidia platform controller and framework listed.
It seems unusual. In your BIOS, is there a way to turn off the dGPU? If yes, turn it off and save. Then start the system. After a complete restart, shut down Windows. Power on again and re-enable the BIOS. Save. Windows should now recognize the new device in Device Manager?
My BIOS lacks that feature unfortunately. I'm limited to using Armoury Crate, which hasn't resolved the issue. In the meantime, I might just reinstall Windows to check.
