PC running on Windows 7 shuts down after a few minutes of being powered on.

Hello and thank you for taking the time to read this! My issue is that whenever I turn on my PC after a few minutes of it being turned on it will completely shut down without warning. The only thing that I could think of was that it was overheating so I cleaned out all of the fans which were admittedly very clogged and then monitored the GPU's temperature which never went above 29 degrees before it shuts off. If anyone could help with this issue it would be immensely appreciated.

More info would be helpful to know what you have here:

Computer Make/Model

And are all fans spinning freely that need to be? ( *Some fans have tach's that report the speed of them and if the system doesnt see the fan tach pulse it knows the blade is not spinning and it shuts down to protect even without an over temp condition. )
