Computers that switch off spontaneously often have issues with overheating First, be sure all air vent pathways are clear for at least several inches Next, be certain both your power supply and CPU fans are operative If your CPU is set into one of those nifty office console cubbyholes they make these days, it may not be getting the ventilation flow it needs.

Check the inside of your fan and case, and especially around the CPU heat sink for dust or pet hair A can of compressed air, purchased at office supply or electronics stores for just such purposes can help blow out the dust

Wheever the heat sink is removed from the processor for ant reason, replacement heat conductive grease, or a new heat conductive pad is required.

If that doesn't clear it up, a trip to the shop is recommended
