First, change the hard disk mode. Press F2 (or other key, displayed on the screen) to enter BOIS, find "ATA" mode and see if it is "IDE" or "ACHI" mode. Make changes and press F 10 to save.
Second, after booting, enter the system selection, press f8 to select the last correct and effective configuration (which can solve the error caused by the driver installation error) and the safe mode with network connection (there is a network after entering, and then get rid of it with 360 software), which may be repaired.
3. Enter "Safe Mode" and enable the "System Recovery" function to restore the system to the last normal startup time. If the "System Restore" function is not turned on in your system, all the drivers, programs and patches you recently installed will be downloaded.
4. If you can't enter the "safe mode", there may be something wrong with the system. Recommend to reinstall the system.
5. Memory problems. Unplug the memory stick, carefully wipe the golden finger with an eraser, and clean the dust on the card slot. Insert the memory module again.
6. Disassemble the back cover and thoroughly clean the dust on the motherboard and fan.
Seven, the hard disk has a bad way. It is recommended to use disk bad track detection software for detection and repair.
If it doesn't work, then send it to repair and say that the hard disk is broken.
