The display card of miner can be inserted into the computer with

1. The graphics card is damaged or the power of the graphics card is too high to carry

2. It should be the reason for the improper setting of the graphics card in the BIOS of the motherboard.

3. The first step is to check whether the power supply is connected, especially the switch on the terminal board. When the computer is turned on and the power indicator on the host panel is not on, it is generally caused by the external power supply
the second step is to check whether a plug-in device has been added. For example: U disk is inserted before boot. Some machines default to the U disk as the first boot disk, and your U disk does not start the program, so the computer can not start. Solution: first unplug the U disk and then start the computer, and then plug in the U disk after successful startup.

4. You can change that graphics card to another computer and have a try. 80% of this is e to graphics card problems. Another 20% is because your computer doesn't have enough power. Or you didn't install it right.

5. Hello, friend:
if you plug in the graphics card on the motherboard directly, it can be displayed, but if you plug in the independent graphics card, it can't be displayed. This means that the independent graphics card has failed. It is recommended to repair the independent graphics card
I hope it can help you. I wish you happiness~

6. Try the display of the integrated display. If the integrated display can display, check whether there is a problem with the single display, or check whether there is a problem with the adapter line

7. If you don't connect the monitor, the graphics card won't work

8. Does not rule out the graphics card motherboard incompatibility. Plug the graphics card several times to see if it is caused by poor contact
in addition, if the graphics card has an independent power supply line, be sure to plug it in. Finally, the brand and rated power of the power supply may also lead to the failure of the display

9. Generally speaking, when you install an independent graphics card, the integrated graphics card will be automatically shielded. If you find that there is still one in the hardware manager, it means that you have inadvertently installed the driver of the integrated graphics card (integrated in the motherboard driver) and you can manually uninstall it. If that doesn't work, you have to turn it on, press del to enter the BIOS and manually close it.
