My computer suddenly start to shutdown without warning a few days ago.Then it will restart again and prompt a choice to start window(normally/safemode and etc).
After a few minute after that will shutdown again and restart.This cycle will continue until i plug off the wire. Recently i bought 1 external hard drive. Don't know if that is the cause for this problem.
Sounds like either a problem with your hardware/software OR yuor machine is shutting down to protect itslef from damage. If you can, check your Event Viewer and look under SYSTEM, look for errors at time of re-boot. Might want to double check all connections indie your machine, especially the CPU and cooler but continue to check RAM, HDD, DVD, etc, etc
