A hard disk virus causes a virus that cannot enter the system

Disc boot up, delete the hard drive - create!

If you are talking about the invalid format of the C drive, then the problem may be in your partition, that is, you have formatted C, and the virus is in D, E, F...

The workaround is full. Back up important stuff beforehand.

It's so fierce, I haven't encountered it yet.

The landlord can try to format the hard drive.

Since it is suspected that the BIOS has been modified, you can clear the CMOS information by discharging the CMOS, you can take out the battery, short the positive and negative electrodes with a metal substance, or some main versions have jumper caps.

If it doesn't work, it's a hardware problem, and your description is a bit messy, and it's hard to judge.

You can combine a friend's machine replacement to see which hardware is the problem.

The reason that causes you to keep restarting is that your machine hits a good virus from a few years ago - "**wave" hehe, congratulations, only redone.

Can you kill the virus in advanced security mode?

Find a system disc first, enter your system, and figure it out.

It's simple.,I've also encountered it.,Change a hard disk is o( o...

It seems to be a hardware issue . Try the hard drive a few times before you see if it will work!

A hard disk virus causes a virus that cannot enter the systemWhat does this mean?

1. The flash BIOS is corrupted. Rewrite the BIOS program (usually by a professional technician) or replace the motherboard.

2. The CMOS is destroyed. Discharge the CMOS and reset it with your computer's setup program.

3. The boot area or main boot sector is destroyed. Some antivirus software can back up and restore the system's main boot area and boot sector information for recovery with this feature. If you can find other computers with the same type of hard drive, the same partition, and the same operating system, you can use it to back up and then restore the virus-damaged boot area or primary boot sector.

4. Loss of files. If there is a backup file, any damage to the disk caused by viruses can be restored through the backup file. If there is no backup file, some more complex operations, such as some file allocation tables are destroyed, need professional and technical personnel to carry out, encounter this more complex situation, you can ask the relevant personnel, the company for help.

Note: The system may be infected with a virus when the following phenomena occur:

1. Some abnormal strings or specific screens suddenly appear on the screen.

2. The screen is constantly scrolling, and the data arrangement is chaotic.

3. The running speed of the system is significantly reduced, and sometimes it is like a crash.

4. The length of the file increases for no reason or the file is suddenly lost.

5. Programs that used to work normally suddenly cannot run.

6. The system is always paralyzed inexplicably.

7. The system often reads and writes to the disk for no reason.

8. The system suddenly cannot enter the C drive.

9. The available storage space of the disk is suddenly reduced for no reason.

10. Suddenly add new files to the disk, including hidden files and files similar to file names and system file names.

11. The disk file allocation table is suddenly corrupted.

The most radical way to do this is to repartition and reinstall the system. In my experience, antivirus software can't completely remove viruses.
