Since you said tower, these problems are typically caused by one of two things. #1 the power supply is beginning to fail. It happens on new or old towers alike. When a computers power supply (400WT) begins to provide less power than the tower needs to, the computer will shut off and restart. That is one cause. The second cause could be faulty memory. The same will happen with memory when it starts to go bad, the PC will shut off and restart. Typically a power supply will not allow the user to restart the computer after it gets shut down for a short while; however, the power supply is typically always my first guess. Hope this helps.

Cords touching one another, not being plugged in all the way, stuff like that is typically first response because it's free; however, it very rarely will ever fix the problem. Keep us updated.
