It is most common with Processors that come with internal graphics processing unit.

If your GPU is not being identified or you are not having a display after your computer starts, make sure to be certain that you have put the power cable that is needed for the GPU to work properly. Most GPUs these days need a separate power supply to work. Check if your graphics card has a power connector on top of it as shown in the image above. The connector can be a 6-pin, 8-pin, 6+8-pin or an 8+8-pin.
Step 4- Update the Bios
If your GPU is not being detected, then make sure your BIOS is up to date. There are many occasions where a BIOS update can fix the detection issue of the Graphics card unit. This issue is most common with old motherboards where the user, uses new graphics cards on them.
Step 5- Recheck the I/O Cable
If your Graphics card is powered up and all the fans are working on it but still you are not able to get a display, then make sure the display cables like VGA, HDMI, DVI, DP, etc are connected properly to your GPU. On many occasions, users connect their cables to the motherboard port instead of connecting them to the port of the Graphics Card and the result is there will be “no” display.
The above-mentioned steps are the basic part to check and be ensured that your GPU unit is working fine and like every equipment or electronic products need periodic maintenance which results in a longer life span of that product.
