Various diagnostic methods for failure to start the operating system are as follows:
First check whether the computer has started to start the operating system when it is turned on. If it crashes, blue screen, or automatically restarts when starting the operating system, it means that the hard disk partition table and master boot record are normal, and the causes of the problem include damage to the hard disk partition table, damage to the hard disk master boot record, and loss of the hard disk partition end mark. Then use the following method to diagnose.
Step 1: First start the computer in safe mode and see if it can start. If it cannot start, it may be due to virus infection, system file loss, operating system damage, bad sectors on the hard disk, conflict with hardware devices, or hardware problems. ; If safe mode can be started, it may be caused by incompatibility between the hardware driver and the system, a problem with the operating system, or a virus infection.
Step 2: Then run the anti-virus software. If there is a virus, it may be caused by a virus. Restart the computer after anti-virus. If it is still not normal, you need to reinstall the operating system.
Step 3: If no virus is detected, you can use the "System Restore" function that comes with the operating system to restore the system. If the system is normal after restoration, the failure is caused by system damage. If the fault persists, it may be caused by the incompatibility of the device driver with the system; then delete the drivers for the sound card, graphics card, network card and other devices, and then install the drivers one by one. Restart the computer after each device is installed to check whether After finding out which device driver caused the fault, download the new version of the driver for the faulty device and then install it.
Step 4: If you cannot boot from safe mode, then use the installation CD to reinstall the operating system. If the operating system can be installed normally, go to step 7; if there is a failure when installing the operating system, such as a crash, blue screen, restart, etc. that prevents the system from being installed, it should be caused by hardware problems or poor hardware contact.
Step 5: Then clean the dust in the computer, clean the gold fingers of the memory, graphics card and other equipment, reinstall the memory and other equipment, and then reinstall the operating system. If the system can be installed normally, the fault is caused by poor contact.
Step 6: If you still cannot install the system, the failure may be caused by hardware problems. Then use the replacement method to check for hardware faults, and replace the hardware if found.
Step 7: If the operating system can be installed normally and the fault disappears after installation, the fault is caused by damaged system files.
Step 8: If the fault persists after installing the operating system, it may be caused by bad sectors on the hard disk or the device driver being incompatible with the system. Start the computer in safe mode. If it cannot start, the problem is caused by bad sectors on the hard disk. Then use NDD Disk Utility to repair bad sectors.
If the above method does not work, you need to reinstall the operating system and discharge the BIOS battery (remove the battery and reinstall it or press F9 to restore the initial BIOS settings). It is recommended to plug and unplug the graphics card and memory, clean it, and polish the graphics card and Memory cheats. The method to reinstall the system is as follows.
