RB 2011L-IN problem

Hello. I’ve got Mikrotik RB 2011L-IN and yesterday it’s just stop working.

After reboot it’s only Pwr led is on. Other led’s is off.

Then i’ve tried to reboot it several times with no luck.

Then i turn it off and wait for about 3-4 hours.
Then I turn it on and it start fine. I’ve login into Winbox and it was OK. All my settings was fine.
But I’ve got kicked from winbox every 1 minute, but pings to Mikrotik was fine.
Then I make System>Reset configuration and after reboot Mikrotik didn’t work again. Just PWR led is on.
Seems it’s hardware trouble? Heat for example?
Thanks!

Try another power adapter.
