I have Samsung Galaxy I9060 and may restarts by itself because it asks me for pin code
again or asking for pin code on its own. What should i do?

Try clearing the system cache. Have you installed any new apps, as it sounds like something is waking up the phone. Notification or alarm maybe.

I cleared system cache but still not fixed. I didn't installed any new apps. Notifications and alarms were working without problems before. But i replaced device's sound files (alarm, button sounds, notifications, ringtones) with higher volume audio files.
