Extended information:
Since the computer has reported an error, it cannot enter the system. From the installation method, you can use the following steps:
1. Download the required system win7 iso image to the local hard disk, right-click and use WinRAR and other tools to extract it.
2. Place the largest gho file such as win7.gho and the one-click ghost tool in the same directory, such as the D drive, not the C drive or desktop.
3. Double-click to open the one-click ghost reinstallation tool, select "Restore Partition", select the win7.gho file as the image path, select the location of the system disk, such as C drive, or select the installation location according to the disk capacity, and click OK.
4. A dialog box pops up, click Yes, and restart the computer immediately to restore the computer.
5. After the computer restarts, the Onekey Ghost option appears in the startup menu, and the computer will automatically select this option to enter.
6. Start to enter this interface, perform the operation of restoring the win7 system to the C drive, and wait for the progress bar to complete.

8. The reinstallation process usually takes 5-10 minutes. After finally restarting and entering the new win7 desktop, the one-click ghost reinstallation process ends.
1. First, we conduct a comprehensive check on the connection between the computer monitor and the host, and re-plug each connection to see if there are any connection problems.
2. If the fault still exists, then we need to open the case to see if it contains metal or other substances that may cause a short circuit in the computer host circuit. Then we smell the computer to see if there is a burning smell. Look around the motherboard and around the CPU for damaged components.
3. After checking the entire chassis, if there is no abnormality in the chassis, we will treat the dust on the chassis.
4. If the computer cannot be turned on, then use the minimum system method to unplug the data cables of the hard disk, floppy drive, and optical drive, and then check whether the computer can be turned on. If a startup screen appears on the computer monitor, it means that the problem is in these devices. . Then connect more than one device to the computer one by one. When a certain device is connected, the fault reappears, indicating that the fault is caused by this device. Finally, focus on checking this device.
5. If the fault still exists, it is likely to be a fault with the memory card, graphics card, CPU, motherboard, etc. At this time, we only need to plug and unplug the hardware, or replace it again, and try one by one to find the cause. location.
6. If the memory, graphics card, CPU and other devices are normal, then discharge the BIOS, use the isolation method, place the motherboard outside the chassis, and connect the memory, graphics card, CPU, etc. for testing. If the computer can display, then try again Install the motherboard into the chassis and test until the cause of the fault is found. If the fault persists, the motherboard needs to be returned to the manufacturer for repair.
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.
