My Inspiron 5770 will randomly power itself off, as if the processor is overheated.
I have run both ePSA and Dell online diagnostics and no problems are found.
The shutdown typically happens when I am using Audacity software, but it has also happened when using iTunes, Firefox, or even once when the machine was just booting up. This used to happen occasionally (maybe once a month) but now it is happening more frequently, twice a week or more, making the machine virtually useless.
The BIOS and all drivers are up-to-date.
For a machine only 15 months old, this thing sure broke down quickly. Meanwhile, my 20-year old Toshiba laptop still runs fine.

Have you checked the Event Log???
How to Read Shutdown and Restart Event Logs in Windows:
Thanks to your suggestion I checked the event log. The only log item I found in relation to the abrupt power-off is when I power the computer back on.
Event detail: The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
Event source: Kernel-Power
Event ID: 41
I checked the log for events that occurred previous to an Event ID 41 and cannot find anything out of the ordinary. Keeping in mind I am not a expert at such diagnoses and wouldn't know what to look for.
