Error: MySQL shutdown unexpectedly - XAMPP

I have trouble running mysql using xampp on a win10 machine. Here is the xampp message:

Error: MySQL shutdown unexpectedly.
1:33:01  [mysql]    This may be due to a blocked port, missing dependencies, 
1:33:01  [mysql]    improper privileges, a crash, or a shutdown by another method.
1:33:01  [mysql]    Press the Logs button to view error logs and check
1:33:01  [mysql]    the Windows Event Viewer for more clues
1:33:01  [mysql]    If you need more help, copy and post this
1:33:01  [mysql]    entire log window on the forums

And this is my mysql.log:

InnoDB only wrote those files full of zeros, but did not yet use them in any way. But be careful: do not remove old data files which contain your precious data!

I have tried reinitilizing mysql data folder, deleting ibdata1, ib_log files from it, without any success. Any suggestions are much appreciated.

XAMPP MySQL is not running

Solution-> 1.Open cmd and type 'services.msc'

2.Service panel will be opened within 5 seconds

3.Now search for anyother sql server which is still running

4.Select all the sql servers and stop them one by one service(There could be more than one)

5.Finally refresh your computer and start MySQL

6.Enjoy

Hope it will run successfully now :=)
