Black box flashes open then closes quickly

Hi,

There may be several reasons why this black box came up while you were streaming online. To isolate what may be causing this, kindly answer the questions below:

• When did this issue start?
• Have you made changes on your computer lately?
• Does the black box appear even if you are not streaming videos online?
• Does it appear if you are not on full-screen?
• What troubleshooting steps have you tried?

You may also try to run the System File Checker tool. This is a utility
in Windows that allows us to scan for corruptions in your system files and restore corrupted files.

We're looking forward for your response.

 

Laptop went black and won;t reboot

Hi Andree,

Hardware and software conflict is one of the possible reasons why you're experiencing black screen. Sometimes, it is also because of hardware failure. To get this issue fixed, we suggest that you
boot into Safe Mode by following these steps:

• Turn off your computer 3 times while booting. Windows should automatically boot to the Recovery Environment after 3 unsuccessful attempts in a row.
  
• Once you are within the Recovery Environment, select Troubleshoot, and then
  Advanced options, then Startup Settings, and
  Restart. When it restarts, you should see a number of options. Press 5 or F5 for
  Safe Mode with Networking.

Once your computer is in Safe Mode, please follow the workaround provided on this
link. Simply select the similar case that you're experiencing to show the troubleshooting steps.

Let us know how it works.
