I am running a Lenovo think pad U460s and as of recently whenever i switch from my integrated graphics to my dedicated graphics (Nividia Geforce 305m), my computer will run for about a minute before it shuts down. No blue screen no error message nothing. What can I do to solve this?

I did that and it came up with this,

ACPI thermal zone ACPI\ThermalZone\TZ00 has been enumerated.
_PSV = 273K
_TC1 = 0
_TC2 = 0
_TSP = 0ms
_AC0 = 0K
_AC1 = 0K
_AC2 = 0K
_AC3 = 0K
_AC4 = 0K
_AC5 = 0K
_AC6 = 0K
_AC7 = 0K
_AC8 = 0K
_AC9 = 0K
_CRT = 400K
_HOT = 0K
_PSL - see event data.

But honestly i don't understand what this means other than it is a thermal problem.
And if it is just a "normal" thermal problem what can i do to fix it?
