Black screen when powering on PC. Fixed by removing power plug, plugging back

Question

I have a weird problem with my desktop PC. Sometimes (not all the time), after I power up the PC, the display shows a black screen. Nothing shows up. The PC was powered on successfully as I can see the LEDs light up on the casing. To fix this problem, I pressed and hold the power button to shut down the PC first, then removed the power plug. Wait for a pop sound, then plug back the power plug. After doing these steps, the PC boots up normally and the monitor shows the BIOS boot up screen.

I am running Windows 10.

PC configuration: - AMD Ryzen 7 2700x - Nvidia GT 710 - Motherboard B450 Aorus pro Wifi - DDR4 RAM 16Gbyte 2133Mhz clock - SSD 1 Terabyte

Answer 1

Potential causes of a black screen:

1. Installation in progress

   How to fix:

   The best thing you can do in this situation is to wait, but if it's been anywhere between 3 to 6 hours, then chances are that the installation process is stuck.

   If the installation is stuck, you should try shutting down your device completely. [...] disconnect all the non-essential peripherals, including external storage, phone, printer, game controller, network cable, and secondary monitor. If possible, also turn off your Wi-Fi and Bluetooth adapters. Only leave connected to your computer the essentials: keyboard, mouse, and display.

   Wait 60 seconds, reconnect the battery and power cable, but do not reconnect any of the peripherals, and power on your computer.

   If this was a mere hiccup, the installation process should resume and complete successfully.

2. Loose Connections and/or Driver issues

   To Fix:
   

   • Check to see if your display is connected properly to your computer and to power.
   • If possible, change the video port (e.g from VGA to HDMI). There may be a driver that needs to be updated or reinstalled.
   • Disable the discrete graphics card, switching to the integrated one -- this'll tell you if it's your graphics card or the drivers used for it. You can uninstall and reinstall the drivers to see if that helps. If not, I would check to make sure everything is connected to your discrete graphics card properly -- ASUS Nvidia GT710 Installation (This is just the first video I found, but there are plently more if you need them.)
   • Try a different monitor and/or cables -- yours could be dying, have a bad connector, etc.

   • If the computer isn't detecting the display, then you can try using the Windows key + P keyboard shortcut, press P again and then Enter. You'll need to repeat this steps a number of times to cycle through all screen options.

   • [...] use the Windows key + Ctrl + Shift + B keyboard shortcut to wake up your display.

3. Something connected to the computer is causing problems

   Disconnect everything you can so you're only left with the essentials -- i.e. tower, keyboard, mouse, monitor -- restart, then slowly reconnect things one at a time until you find the one causing the problem. Check the drivers for the device, update (and/or reinstall), and restart. If it's still a problem, you'll need to troubleshoot with the product's support center.

4. Other (more complicated or obscure reasons)

   To Fix:
   

   • Reboot into Safe Mode
     Use the troubleshooting tools in the advanced startup menu to try to track down the problem
   • Backup your computer and do a clean reinstall. (It's far from ideal, but it can fix errors from a corrupt OS; and I have found this has worked for me before when Microsoft Support couldn't figure out what was wrong.) You can migrate over your files, settings, etc. if this solves the problem.
   • Check if the GPU is referenced properly in BIOS. Someone else had this problem.
   • Try Rolling back the Integrated Graphics Driver
