I get similar very vague statements when people tell me their computer "just stopped working".
One of the more recent ones was brought into my office unable to boot. She told us it had overheated because it was "left in the sun".
Okay... Was it powered on while in the sun?
Hmmmm, was it in a hot car?
Okay... So we're in northern Minnesota, where a "hot" day is about 90 degrees in the middle of August. Not hot enough to cook a powered off computer, and never seen one left in a car be overheated.
So I crack it open and immediately see a stain where some liquid had been poured on it. Flip it over and remove the bottom cover, big pool of viscous liquid remnants on the CPU.
Sniff it... It's sunblock. (I'm a ginger, I have an intimate relationship with sunblock)
So, uh... How'd you get sunblock inside the computer?
Well, someone did....
So she's a mental health professional for the client I am stationed at three days a week, so we just hand her a new laptop, transfer her hard drive over, and she's up and running.
Several months later... I'm on an emergency virus removal working till 10:30 one night and I get to her new computer.
Open it up, big stain across the screen and into the keyboard.
Some people can't be taught.
So, long story and all, but mechanics have to get the same stuff.
It just stopped running.
What were you doing when it happened.
I dunno, nothing....
Now, nothing against the original poster. Perhaps one of the valve retainers wasn't secured properly. Maybe a cam cap wasn't fastened. They're under warranty for a reason. Just saying the odds aren't favorable.
