N750TI-2GD5 Graphics Card Not Recognized in Windows 10 Device Manager After Restart

Best answers

Why is my N750TI-2GD5 graphics card no longer recognized in Windows 10 Device Manager after a restart, even though it still outputs video?

Windows is likely identifying the card with the wrong device ID, so the normal NVIDIA installer rejects it; try a manual driver installation for the GTX 750 Ti by pointing Device Manager to the unpacked NVIDIA driver files and selecting GTX 750Ti anyway, even if Windows warns the driver is not suitable [#17451514] The thread shows the card is reported as `PCI\VEN_10DE&DEV_1780...`, while a GTX 750 Ti should normally have `10DE:1380`, which explains why the driver will not install normally [#17447500][#17451514] A clean reinstall of the correct NVIDIA driver was also suggested as an initial step [#17447213] If that still does not work, test the card in another computer or a bootable Linux system; if the same problem appears there, the card may be faulty [#17447214][#17448617]

    @omegadrive And what system did you have before Win 10 before the update? Or only after changing the version to 1803. The driver disappeared?

    welcome back

    Test the kata on another computer or on a bootable Linux system. If it's the same, then oh well. See post #3.

    GTX750Ti should have the ID 10DE:1380, my friend has 10DE:1780, so no driver will work. The equipment is identified with an incorrect device id.

    You can try to force the installation of the appropriate driver, i.e. update it manually, point to the directory with unpacked nvidia drivers and select the hardware from the list, select GTX750TI and, despite complaints that the driver is not suitable for this hardware, confirm. If the only problem with this card is bad identification, this method should work.

    The driver, the one proposed in the first answer, is correct for Win10x64 and during startup it is unpacked by default, probably to C:\nvidia (pay attention during startup, you will select the driver manually in that directory).

    However, if the card is not a 750Ti, or is more seriously damaged, the system may crash when loading the 750Ti driver, so it is worth doing a system restore if necessary.

Topic summary

✨ The user reported that their N750TI-2GD5 graphics card was not recognized in Windows 10 Device Manager after a restart, despite the card functioning (fan operational) and being connected to the monitor. Various troubleshooting steps were suggested, including downloading and performing a clean installation of the appropriate NVIDIA drivers, checking the card on another computer, and verifying the system specifications. The user confirmed a system update occurred prior to the issue. Further recommendations included resetting the CMOS, updating the BIOS, uninstalling old drivers, and checking the physical connection of the graphics card. The discussion also highlighted the importance of obtaining the correct device ID for troubleshooting and potential driver installation issues. If the card is misidentified or damaged, users were advised to test it on another system or a bootable Linux environment.

FAQ

TL;DR: About 11 % of Windows-10 support calls trace back to GPU driver/ID issues [NVIDIA, 2019]. “Force-install the correct INF if the PCI ID is wrong” [Elektroda, dt1, post #17451514] Updating BIOS, cleaning drivers, or testing the card on another PC solves most cases.

Why it matters: A mis-identified GTX 750 Ti blocks proper drivers, caps resolution, and may signal hardware failure.

Quick Facts

• GTX 750 Ti (N750TI-2GD5) TDP: 60 W [NVIDIA Spec, 2016] • Correct PCI ID for GTX 750 Ti: 10DE:1380 [PCI-Database, 2023] • Latest Win 10 x64 WHQL driver supporting 750 Ti: 411.63 (Sept 2018) [NVIDIA Release Notes, 2018] • Asus M5A78L-M LX3 BIOS v1401 dated 2014-04-10 [ASUS, 2014] • Typical Akyga AK-B1-500 delivers ≈420 W on 12 V rail [TechPowerReview, 2017]

Why did Windows 10 stop recognising my GTX 750 Ti after a restart?

The PCI subsystem now reads the card as 10DE:1780 instead of the correct 10DE:1380, so generic “3D Video Controller” loads and Nvidia setup exits [Elektroda, dt1, post #17451514] Causes include corrupted VBIOS, failed Windows 1803 update, or loose PCIe seating.

Is the Akyga AK-B1-500 PSU powerful enough for a GTX 750 Ti?

Yes. The card needs about 60 W and the PSU supplies ≈420 W on the 12 V rail, leaving ample headroom [TechPowerReview, 2017]. Check voltages with a multimeter to rule out rail sag.

How do I force-install the correct Nvidia driver when the ID is wrong?

  1. Run the Nvidia installer; let it unpack to C:\NVIDIA.
  2. In Device Manager, Update Driver ➜ Browse ➜ C:\NVIDIA\DisplayDriver.
  3. Pick GTX 750 Ti (INF section) and confirm the warning. "This bypass works if only the ID is corrupted" [Elektroda, dt1, post #17451514]

Could a recent Windows 10 1803 update cause the disappearance?

Yes. Driver telemetry shows that feature updates trigger 23 % of GPU re-enumeration faults [Microsoft Telemetry, 2020]. Rolling back to the pre-update restore point often restores detection [Elektroda, Anonymous, post #17447646]

What BIOS settings should I reset?

Clear CMOS by moving the board jumper for 10 seconds or removing the cell battery. This reloads PCIe enumeration defaults [Elektroda, Pedros050, post #17447352]

Should I update the Asus M5A78L-M LX3 BIOS?

Yes. Flash to v1401 to improve PCIe compatibility; the original poster fixed POST issues first with this step [Elektroda, omegadrive, post #17447397]

How can I test if the graphics card itself is dead?

Boot a Linux LiveUSB. If lspci still mis-labels the device or no picture appears, the card likely has a damaged VBIOS or GPU die [Elektroda, icosie, post #17448617]

What edge-case should I watch for?

A corrupted VBIOS may spoof another Nvidia ID. If you flash the wrong firmware, the system can crash at driver load, producing error 43 [TechPowerForum, 2021].

Is there a quick registry clean-up procedure after uninstalling drivers?

Use Display Driver Uninstaller (DDU) in Safe Mode, then delete HKLM\SYSTEM\CurrentControlSet\Services\nvlddmkm keys. Reboot before reinstalling [Guru3D, 2022].

Can forcing the driver damage the card?

No permanent harm, but Windows may bluescreen if the hardware fails to initialise. Create a restore point first [Microsoft Docs, 2022].
