If you are experiencing problems with your graphics processing unit (GPU) not being detected by Windows, there are a few steps you can take to try and troubleshoot the issue.
1. Check the connection of your GPU
The first step is to check the connections of the GPU to make sure it is securely inserted into the slot and that the power cord is connected properly. Some GPUs have additional cables which should also be checked to make sure they are connected properly.
2. Update Your Video Driver
The most common cause of GPU’s not being detected by Windows is outdated video drivers. The video driver manages the communication between your operating system and the graphics hardware, so if the driver is outdated, it can cause the GPU to not be detected. To update the driver, you can use Windows Update or download the latest driver from the manufacturer’s website.
3. Check the BIOS
The BIOS is a set of instructions on the motherboard that tell the computer how to configure certain settings, such as recognizing the graphics card. If your GPU is not being detected, it may be that the BIOS is not recognizing the card. You can check this by entering the BIOS when you start up the computer, which can be done by pressing a special key while the system is booting. If the GPU is not showing in the BIOS, then you will need to enable it or update the BIOS.
4. Reseat the GPU
If all else fails, you should try removing and reseating the GPU in its slot. This can sometimes help because the PCI-E slot may not have been making good contact with the card, which can then cause it to not be detected by Windows. Make sure to turn off the power supply before doing this.
If these steps still do not solve the issue, then it’s likely that your GPU is defective and needs to be replaced. In this case, you should contact the manufacturer for assistance.
