![]() If you suspect hardware is causing a conflict, disconnect all the peripherals, including printers, cameras, removable drives, dock station, Bluetooth, and other USB devices, and then restart the computer. However, if the device is taking a very long time, you could be in front of a compatibility problem. In this case, you will need to wait a few minutes to get to the sign-in screen. Usually, when the computer starts up and hangs with cycle animation, it could indicate an update is currently being installed on the computer.

In case this is an external monitor, open the display's control panel and adjust the brightness level to fix the black screen problem. (You may need to check your hardware manufacturer's website for details on how to proceed.) If you suspect this could be the case, open the computer case, remove the card from the motherboard, and reinstall it again. If you have a traditional desktop computer with a discrete video card, the hardware may not be fully making contact with the motherboard's slot. If you recently updated the UEFI (Unified Extensible Firmware Interface), this action can sometimes disable the discrete graphics card, which you can only re-enable from the motherboard firmware. I want this to serve as a public service announcement for others out there that this is happening.In case the system features an integrated graphics card on the motherboard and an add-in discrete card, you may want to switch the video to the embedded graphics to confirm if the problem lies in the discrete card.
