Why does a bunch of numbers pop up when I turn on my computer

Solution:

1) This is because the system is scanning your hard drive. It may be a problem caused by your own operation. If you shut down illegally, cut off the power directly or press the power button to turn off the power, the computer will check your hardware when it is turned on, including your hard drive.

There is also a problem with your computer's hard disk. It is recommended that you use the disk scanning tool that comes with your computer to scan and repair it. If it is more serious, use the following software to repair it (if it does not scan next time after this scan, it is normal) Scan, if the hard disk is always scanned when booting, please see below and try to repair the disk according to the following method).

2) If there is no illegal shutdown and there is no problem with the hard disk, and the system still scans when you turn on the computer, you can use the following method to remove the system from scanning the hard disk:

Click "Start/Run", enter "regedit" and press Enter to open the registry editor, select the "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager" subkey in sequence, and then find "BootExecute" in the right window Clear the key value items and their value data, and then restart (select the file export for backup before clearing, so that you can restore the backup if needed).

3) The system’s own disk repair method (if you always turn on the computer to check, use this method to repair a certain disk):

The specific steps are as follows: Select the drive letter in My Computer and right-click the mouse. In the pop-up drive properties window, select "Tools → Start Checking" and select "Automatically Repair File System Errors" and "Scan and Recover". Bad Sectors", and then click Start. The scan time will vary depending on the disk capacity and scan options (after following the above method, a box will pop up, click Yes, it will automatically shut down and then start up to repair).

Bad sectors on the hard disk will cause the computer system files to be damaged or lost, and the computer will be unable to start or crash. Bad sectors on the hard disk can be repaired using NDD Disk Utility or Scandisk.

4) If the problem still cannot be solved, restore the system or reinstall the system. If that doesn't work, format the hard drive, repartition the system, and reinstall the operating system. If that doesn't work, replace the hard drive.
