acer e1 571G model .it shutdown randomly .i had changed the battary but the problem is not solved

Solution
Could be dead motherboard. Does the system not turn on anymore at all? Try unplugging the battery, remove the CMOS battery from the motherboard, hold in the power button for 30 seconds, then plug in wall power only (no batteries) and see if it turns on. If it does, plug in he CMOS battery in again and see if that works.
