RTX 5070 Not Showing in Device Manager: Fix

Quick Answer

If your RTX 5070 is not showing in Device Manager, the most common causes are a missing or corrupted driver, an incomplete PCIe slot seating, or a BIOS setting that is disabling the discrete GPU. Reinstalling the latest NVIDIA driver and reseating the card in the PCIe slot resolves the issue in most cases.

Why the RTX 5070 Disappears from Device Manager

When Windows cannot detect your RTX 5070 through Device Manager, it usually means the operating system cannot communicate with the GPU at the hardware or driver level. The card may appear under "Unknown Device" or "Other Devices" with a yellow exclamation mark, or it may be completely absent from the list. Common hardware causes include the PCIe power connectors not being fully clicked in, the card not seated flush in the x16 slot, or a riser cable failure if you are using a vertical GPU mount. On the software side, a partial driver installation, a Windows update that broke the existing driver stack, or a conflicting legacy NVIDIA driver left over from a previous GPU are frequent culprits. South African users who have experienced loadshedding-related shutdowns should also check whether a sudden power cut interrupted a driver install and left the system in an inconsistent state.

Step-by-Step Fixes to Try

Start by shutting down completely, unplugging the power supply, and reseating the RTX 5070 firmly into the PCIe x16 slot closest to the CPU. Reconnect all 16-pin or 12VHPWR power connectors until they click. Boot into the BIOS and confirm that the primary display output is set to the PCIe slot rather than integrated graphics, and that "Above 4G Decoding" and "Resizable BAR" are enabled, as the RTX 5070 requires both for stable operation. Once back in Windows, open Device Manager, select View and choose Show Hidden Devices. If the GPU appears greyed out or flagged, right-click and uninstall the device, then use Display Driver Uninstaller (DDU) in Safe Mode to remove all traces of any existing NVIDIA driver. Reboot, download the current NVIDIA Game Ready or Studio driver from nvidia.com, and do a clean install. If Device Manager still shows nothing, try the card in a different PCIe slot or test with another machine to rule out a hardware fault.

When to Suspect a Faulty Card or Slot

If the RTX 5070 is invisible in Device Manager across multiple PCIe slots and two different driver installs, the fault is likely in the card itself or the motherboard's PCIe controller. Test the GPU in a known-working system if you can. South African consumers purchasing hardware locally should note that graphics cards bought from a reputable retailer carry a standard warranty, and if the card arrived in South Africa and failed within the warranty period you are entitled to a replacement or repair. Before initiating a warranty claim, document the troubleshooting steps you completed so the process moves quickly.

FAQ

Why does my RTX 5070 show up in BIOS but not in Device Manager?

The BIOS detects hardware at a low level before the OS loads, so if the GPU appears there but not in Windows Device Manager, the problem is almost certainly driver-related. Boot into Safe Mode, run DDU to clean all NVIDIA drivers, and reinstall fresh.

Can loadshedding damage a GPU or cause Device Manager detection issues?

A sudden power loss mid-driver-install can corrupt driver files and cause the GPU to appear broken to Windows. It is unlikely to physically damage the card unless the PSU failed and sent a voltage spike. A clean driver reinstall after an unplanned shutdown usually restores detection.

Is Above 4G Decoding required for the RTX 5070?

Yes. The RTX 5070 needs Above 4G Decoding enabled in the BIOS to map all of its VRAM properly. Without it the card may not be detected correctly by Windows or may operate at reduced capacity.
