Then get help. There is medication that can suppress feelings. The numbers I linked aren't just for suicide prevention. Getting help for other mental conditions is a related thing. It's basically the same doctors/therapists. Just don't self-medicate, that won't get you anywhere.
If you're serious about what you say, ask a doctor. He or she can make you stop feeling. It's probably antidepressants that do that. And they're prescribed by doctors. And if it ain't easy to find a doctor, call the helpline, they have some contacts for people like you...
Why does it force the processor over the limit in the first place?
I think in every other laptop the CPU just throttles when it gets too hot. Meaning it can never exceed the maximum temperature. I wonder if this is a misunderstanding or if HP actually did away with all of that and designed a laptop that will cook itself.
And it's not even a good design decision to shutdown the PC if someone runs a game... Aren't computers meant to run them? Why not automatically lower the framerate by throttling? Why shut down instead?
