[MySQL] connessione db

[oscar]

buongiorno, xampp installato su windows e funzionante fino questa mattina quando aperto il control panel di xampp, apache si connetta bene ma mysql no e dà il seguente messaggio :
Error: MySQL shutdown unexpectedly.
11:04:32 [mysql] This may be due to a blocked port, missing dependencies,
11:04:32 [mysql] improper privileges, a crash, or a shutdown by another method.
11:04:32 [mysql] Press the Logs button to view error logs and check
11:04:32 [mysql] the Windows Event Viewer for more clues
11:04:32 [mysql] If you need more help, copy and post this
11:04:32 [mysql] entire log window on the forums
possibile soluzione? grazie.
aggiungo log di errore :
