IMO, I think it may be an overheating issue, but it also might be 1) your computer overreacting to heat and force shutting itself down or 2) a virus. or 3) Strange background processes jacking the heat up.
It actually happened to me so many times. I had to reset and format my entire laptop 5 times. It would not crash / force shutdown for a week, then it would start again, then I would reset it again etc.
Resetting didn't work for me, but then I thought, 'what if it was one of my programs I was installing?'
So yeah. I downloaded one program, waited a week. Nothing happened. etc. Until I installed adobe creative suite (photoshop, flash etc), it began acting up again.
This time, I reset my laptop, installed everything EXCEPT for creative suite, and now i have a normal laptop that will actually let me work without killing itself every 15 minutes.
I don't know why. I tried installing adobe suite again to see if it would give me some mercy, but nah. It's definitely adobe suite.
But it's very strange. Either my laptop doesn't like Adobe Suite, or Adobe suite has some sort of virus.
I can't really think of it having a virus, I mean, come on, 1) it's Adobe and 2) it's a legal copy, not pirated etc
That's kinda the only shit I can contribute here. I dunno if this information helps or not.
P.S. DON'T RESET OR FORMAT WITHOUT BACKING UP A COPY OF EVERYTHING YOU HAVE
since i was genius i forgot what 'formatting' was and just clicked it without backing shit up
