Check first if you can boot to safemode to see if the problem is persistent. Or connect and external monitor to rule out also the problem. You could also reseat the RAM module/s or if you have 2, try using one alternately on 2 slots. Make sure the fan is also in good working condition as you boot the laptop. Check for any loose, damaged wire/cable. Any previous issue that might have come to this case?

   As booting up(even before it shutsdown), check the ventilation if air is coming out...
