This is most likely an overheating CPU. The motherboard has a sensor for heat. When the motherboard (BIOS) detects heat past a safe threshold the motherboard will shut the computer down to protect the CPU. Solution: Get some canned air and take you computer outside. Open the case and blow out all dust on the areas with fans. Important areas 1) the fan where you see the main cable plug in. 2) The fan in the middle of the board. 3)Any other fans around the case. * Ensure that you hold the can upright so you only blow air nad not fluid. Secondly, plug your computer in with the case open. Watch to ensure all fans are spinning. If they are not spinning have them replaced by a local computer shop. Fans are about $50 and replacement about the same for a trained professional. Heat is the most likely cause for your shut down symptom. I
