SOURCE: emachine w5233 keeps shuting down

Does this happen when you are in your operating system??? and there is prompt that a program or command is promting it shut down, if it is, then it is a viral issue and latest anti visrus needs to be scanned for. If not, then I belive it is a overheating promblem most likely with your CPU. Cpu now come with a technology to override to the computer to shut down when it becomes overheat to prevent it from damaging itself further. Check your cpu fan, you can do this by taking your panel apartby unscrewing two screws from the back of your left side door panel, you then will see the motherboard and inside it you will see a huge fan, try to clean it by blowing off the dust and debris, if possible take the fan out, and apply new termal compund and reesemble to fan back onto the cpu. Make sure it is tight and securely fasten on. You should be good to go, if it still shuts off byitself, then porbraly a bad motherboard, or cpu, which will need to be replaced.
