MY411x - restarting
 

Hello, I am a new user and the reason for me to register on this forum is that recently I am struggling with my phone ...
The problem is that, today, completely out of nowhere, my phone started to restart. OK, it used to restart once per a month or so, but now I cannot even turn this damn phone on xP. Every time I turn it on, display turns on, and like a second later "Shutting down..." message shows up. It turns of and turns back on again and again - continues like this until I take out the battery.
Anyone has any idea what could it be :P?

I would like to mention that I have not modded (or whatsoever) my phone. Nothing unusual happened to it - it just turned off and now opposes to be turned on -_-.

Thanks in advance for any help.
