My Computer Graphic Card Is Not Visible

If you do not see the NVIDIA graphics card listed under Device Manager, we can say that the graphics card is incorrectly detected by Windows. This common error that you will encounter, especially in NVIDIA Graphics drivers, can be caused by many reasons.

NVIDIA graphics card not showing in Device Manager

If there is no video card in Device manager, you need to do the following steps.

Show Hidden Devices and Manually Reinstall Graphics Driver

This step is especially useful for troubleshooting leftover drivers after video card replacement . Follow these steps:

1. Open Command Prompt (cmd) as administrator.

If you are not sure how to open it, refer to the following links depending on the operating system you are using:

How to Open Command Prompt as Administrator in Windows 7, XP and Vista
How to Open Command Prompt as Administrator in Windows 10, 8 and 8.1 2. In Command Prompt,   type set devmgr_show_nonpresent_devices=1  and then  press Enter.

3. In the same Command Prompt,  type start devmgmt.msc  and then  press Enter. This is to open the Device Manager window.

4. When the Device Manager window opens,  click the View  menu and  select Show hidden devices from the drop-down menu  . After that, all devices not connected to the computer will be shown, including the NVIDIA Graphics card.

5. Uninstall each instance of NVIDIA card and unknown device (Unknown device  will be listed under Other devices category.).

To remove the device, right-click the device name and  select Uninstall from the context menu. The screenshot below is for reference.

Note  : NVIDIA graphics card may not show as its device name. Unknown device, video controllers etc. it could be. If you’re not sure how to identify it, simply remove the device with the yellow mark on it.

6. Restart your computer after uninstalling, then Windows will automatically reinstall the driver.

Update Nvidia Graphics Driver

If method 1 does not fix the problem, it is recommended to update the driver to the latest version.

You can go to Nvidia official website to download the latest driver for your graphics card. But if you don’t have the time, patience, or computer skills to manually update drivers,   you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, risk downloading and installing the wrong driver, and worrying about making mistakes during setup.

You can update your drivers automatically with the FREE or Pro version of Driver Easy. But with the Pro version it only takes 2 clicks (and you get full support and a 30-day money-back guarantee):

1)  Download and install Driver Easy.

2) Run Driver Easy and   click Scan Now. Driver Easy then scans your computer and detects the problem drivers.

3) Click the Update button next to the marked Nvidia graphics driver to automatically download the correct version of this driver    , then you can install it manually (you can do this with the FREE version).

Or click Update   All to automatically download and install the correct version of  any missing or outdated drivers on your system   (this requires the Pro version – click Update All and you will be prompted to upgrade).

Restore BIOS to Default

If you are an advanced computer   user, you may already know how to enter the BIOS and restore it to default. If not, contact your computer manufacturer or technician for assistance with this as changing the BIOS settings incorrectly can cause serious problems.

Update BIOS

You can go to the motherboard manufacturer’s website or the computer manufacturer’s website to check and download the latest BIOS version you can update. As updating the BIOS incorrectly can cause serious problems, contact your computer manufacturer or technician for assistance with this.
