Sorry the delay time
Sorry i deleted the first post....so......
As i say to Xian the system start normal....but after some minutes the system self re-boot and i got the crossmatch screen....
Xian told to me try boot the system whitout battery....i do that....but the problem persist....
So i try look more closed in all the board and bingo....i found this : (missing parts)
So i got one dead mv-1b here and replace it whit another similiar....put the battery back and boot the system again.......
Problem fixed.....no more self-re-booting after 4hrs runing some games......
