Actually first things first. When was the last time you opened it up and gave everything a good cleaning, blowing out the fins on the heatsink and all fans? Computers are very good room air cleaners.

If the problem is accurately presented - PC shuts down (no blue screen) after 15 minutes, there can be no mystery - overheat.

A spinning fan is not necessarily a working fan.

Lint build up in intake areas, cooler fins, on fan blades.

PC placed close to a heat vent.
