Hello

·        The black square appears every time that you restart the computer?

·        This occurs in safe mode?

Method 1:

Start in safe mode and check if the problem persists.

a. restart and keep tapping F8 until you reach the start option.

b. Select safe mode from the list and check if the problem still persists.

After safe mode, I suggest you perform a clean boot. Follow method 2.

Method 2:

Maybe the General information that runs on the system causes this problem. I suggest you do a clean boot and see if the problem is resolved.

a. log on to the computer using an account with administrator rights

b. Click Start, type msconfig.exe in the start search box and press ENTER to start the System Configuration utility.

If you are prompted for an administrator password or for confirmation, type your password or click on continue

c. under the general tab, click Selective startup and then click to clear the check box load startup items. (The check box use the file Boot is not available.)

d. on the Services tab, click to select the skin all the Microsoft services check box, and then click Disable all

Note: Following this step lets services Microsoft continue to run. These services include networking, Plug-and-Play, record of events, error reporting, and other services. If you disable these services, you can permanently delete all restore points. Do not do this if you want to use to restore the system with the existing restore points.

a. When you are finished troubleshooting, follow these steps to reset the computer to start as usual:

b. Click Start, type msconfig.exe in the start search box and press ENTER.

If you are prompted for an administrator password or for confirmation, type your password, or click on continue.

c. under the general tab, click the Normal startup option and then click OK.

d. When you are prompted to restart the computer, click on restart.

If the problem is solved, check which third-party program is causing the problem. For more information, see the article mentioned below.
