Kept "overheating" or something, and the store kept saying it was the programs I was using and then the power supply. So we kept swapping them out until they wouldn't let me anymore. The period between startup and crash would start at a few hours and inevitably get down to a few minutes, until I was never sure whether I should PRINT or SAVE my file because either one might increase the chances of a crash...
