XAMPP MySQL service crash after reboot

Question

I just installed an XAMPP 7.3.6-2-VC15 for Windows, 64 bit, and when I install it, it's fine. MySQL start from the control panel without error, etc. All is OK.

After rebooting my PC, Apache is still working, but MySQL refuses to start! I try to reinstall XAMPP, but it's exactly the same. MySQL works fine, and stops working after reboot.

Here are the few logs I have...

In the control panel:

09:48:10  [mysql]     Attempting to start MySQL app...
09:48:10  [mysql]     Status change detected: running
09:48:11  [mysql]     Status change detected: stopped
09:48:11  [mysql]     Error: MySQL shutdown unexpectedly.
09:48:11  [mysql]     This may be due to a blocked port, missing dependencies,
09:48:11  [mysql]     improper privileges, a crash, or a shutdown by another method.

09:48:11  [mysql]     If you need more help, copy and post this
09:48:11  [mysql]     entire log window on the forums

And in the log file:

I try the following:

Change port for other than 3306 => no success
Run xamp control panel as admin => no success
remove temporary table ibdata1 and ibtmp1 => no success

If someone have an idea...

I try to install as a windows service via the administrator panel as administrator. And so, I have some new lines in log. It seems the user table is corrupted... How can I repair it?

This one helped for me:

Open shell from from control panel and start mysql with this command:

mysqld –-console –-skip-grant-tables –-skip-external-locking

Open another shell from control panel and repair database with this command:

mysqlcheck -r --databases mysql --use-frm

Stop mysql, close shells and restart mysql normally.
