Graphics Processing Unit is an important hardware component required to build a high-performance computing system. Any slight deviance in the performance of your GPU can lead to drastic changes that affect your entire system.
Here in this article, we are going to discuss problems related to GPUs, especially NVIDIA graphics cards. There are multiple reports about Nvidia graphics cards not being detected on Windows 10.
There may be a variety of reasons responsible for a situation where your laptop doesn’t detect the graphics card. One such reason and also with most possibility is/are errors involving device drivers.
Outdated graphics card driver or incompatible device driver update(s) installed during a Windows 10 Update session can lead to this “Graphics card not detected” error.
Another possible reason may involve the BIOS of your computer. If the GPU isn’t enabled in BIOS then surely your computer won’t detect the hardware. Moreover, an outdated BIOS version is also incompatible with the latest technological breakthroughs.
How To Transfer CPU Load To GPU?
There are some users with questions about whether it is possible to transfer CPU load to GPU. The answer to this question is NO. Why? Because the modes of information processing for GPU and CPU are totally different.
GPUs tend to execute tasks in parallel and in a very redundant way while the CPU tasks are very complex but sequential. Hence it can be inferred that tasks meant for GPU will be poorly executed by CPU and vice versa.
Therefore there is no way that you can dump CPU workload onto the GPU.
Which Graphics Driver Version Should I Install?
- Open the Run dialogue box by pressing Windows + R on your keyboard.
- Type “devmgmt.msc” and click on the Ok option.
- Expand the Display Drivers option and right-click on the Nvidia Graphics card.
- Click on the Properties option.
- Go to the Drivers tab. Here you can get the details of the Nvidia drivers installed on your computer. Note down the driver version and driver date.
Alternatively, you can also determine the driver version of the current graphics card driver from the Nvidia Control Panel.
- Right-click on the open space of your Desktop screen and click on Nvidia GPU Control Panel.
- On the Nvidia Control Panel, you can see the System Information option in the left bottom corner. Click on it.
- Now you can see a window revealing all of your graphics card information. From here you can note down the currently installed driver version of your Nvidia Graphics Card.
