what causes a computer to shut down
A more rare cause of a computer shutting down randomly can be a computer virus. Some computer viruses will actually shut off your computer, and then turn it back on. These viruses are usually activated by a certain thing you do on a computer, whether itâs a keystroke or opening a particular program.
Issues With Hardware. Any issues with hardware failure may cause the computer to shut off unexpectedly. The most likely culprit would be any new hardware additions, provided your computer was working fine before adding the hardware.
Hereâs what to do about it. Chips and hard drives use electricity, and therefore generate heat. That heat can seriously damage the circuits inside your PC. Luckily, the computer is smart enough to shut itself down when it gets too hot, protecting itself from permanent damage. A PC that suddenly shuts itself down may be a lesser evil, but itâs still something you want to avoid.
