There is a thermal safety setting in the kernel somewhere ... it used to |
| 2 |
do this to me when a cpu heatsink came adrift ... but the cpu had to get |
| 3 |
quite hot to trigger it (was on an Intel core2) so it was ok until it |
| 4 |
tried to do real work ... instant off. |

Try monitoring the temperature. Also, cpu thermal compound/tape can |
| 7 |
lose its effectiveness on older PC's as well as the usual dust puppies |
| 8 |
blocking cooling etc. Also, depending on how it is setup, Linux might |
| 9 |
be running just enough hotter than windows to trigger it. |
