So lately I have been trying to play the sims 3 and its completely shuts off my entire laptop after like 10 minutes of playing.
I have no idea what the problem is... Can somebody please help me?
If it was while playing, doesn't seem like a temperature issue. Are you playing with the laptop plugged in to the wall?
Also, let's try one more test. Could you download Prime95 and Furmark, and run their blend test (prime95) and burn-in test (furmark) at the same time? Watch the temperatures all the time in HWMonitor, you're interested in core temperature and graphics card temperature (if there is one, you never told me what kind of a laptop you have). If you cannot find graphics card temperature in HWMonitor, Furmark has a nice graph of it.
