Tell me how to do ld, I can't, please ask me.

boot crash and restart are related to your improper operation before shutdown, right? For example: playing games, watching videos, operating big things, and using the computer for a long time caused by the card? Or download inappropriate things, the fault will not happen for no reason (if this problem is caused, just pay attention to your computer not sticking, blue screen, sudden shutdown, so it won't happen when you turn it on)?

Press F8 immediately after starting the machine until the advanced option appears. Select "Last Correct Configuration" and press Enter to repair. It is not yet possible to press F8 to enter the safe mode to restore or reinstall the system (if reinstallation is the same, it is recommended to overhaul it. If you can enter the safe mode, it means that you have installed inappropriate things, and all the inappropriate things downloaded before the accident will be uninstalled, or the system will be restored or reinstalled. If your computer is Win8, you can't enter the system.

hardware is the cause. Pull out the motherboard battery to discharge, plug in and out the memory, and clear the graphics card. Check whether there is something wrong with the hard disk. If it doesn't work, go ahead and repair it.

You really can't just reinstall the system. If you can't reinstall it yourself, go to the maintenance office and ask someone to help you. If the machine can't be turned on in any way, it is caused by a sudden shutdown, which has caused damage to the disk. One is to take out the battery of the motherboard and discharge it. The other is to try it on for a while, or it can't be repaired.

one is to put it away for half a day or one day, and sometimes it will recover itself, and the other is to reinstall the system.

as long as you pay attention to your computer, it won't be like this when you turn it on.

your computer may not be able to detect the hard disk (symptoms of hard disk detection: hard disk information is not displayed in IDE detection when booting), so it will display ""reboot and select proper boot device or insert boot media in selected boot device and press a key before entering the system. "the reason of hard disk detection failure:

1) the motherboard BIOS is dead, and you can't remember the hard disk information. If your system date is incorrect, this is probably the reason. Solution: replace the BIOS battery and re-enter the BIOS to detect the hard disk.

2) The IDE cable is of poor quality or not plugged firmly. Solution: change an IDE cable or plug the IDE cable into another IDE slot on the motherboard. Do not connect the cable connected to the hard disk with other IDE devices, such as optical drive. Separate two IDE cables and set the master/slave disk correctly.

3) The hard disk is faulty and may need to be replaced.

4) if your computer can detect the hard disk every time and can't enter the system, reformat the hard disk completely and reinstall the system.

5) Try setting up another hard disk to start (is it wrong).

6) In another case, plugging and unplugging the memory again and clearing the dust can also solve the problem (sometimes because of it).

7) I can't solve it by myself, so I suggest having it overhauled.
