My laptop ASUS G550 turned off suddenly. Did not reboot or anything. No BSOD. No overheating (temps normal). I pressed the startup button, and it started up normally as if nothing happened.

I originally posted on this problem around 12 Feb this year, as an isolated incident, while using MS Word (2007), Windows 8.1. Symptoms then seemed to suggest power (hardware) problem.

But the same scenario happened once again a couple of days ago. The event logs from both events do not point to anything consistent. However, this time, I was again using MS Word, and the power-off happened while I was tapping the down arrow at the bottom of the keyboard, near the number-pad... a barely audible "click" SEEMED to accompany the failure and one of the presses of the down-arrow - not sure if this "click" was from the speakers, my imagination, or elsewhere.

My question is, could the problem be an incompatibility between MS Word 2007 and Win8.1? If so, shouldn't the failure be accompanied by a BSOD, instead of just dying cold? Or, given the absence of BSOD, is it a hardware problem... maybe the key that I was tapping? Important for me to establish, because the laptop is still under warranty, but not for much longer. Do power-offs - NO BSOD - ever happen solely as a result of software/driver incompatibilities? Thanks.
 
Definitely a hardware issue, though I couldn't say specifically what.

Any incompatibility between an application and the OS would be most unlikely to cause sudden shutdown.
Anyway, MS Word 2007 is fully compatible with Windows 8.1:

Thanks. That sounds kinda conclusive. Seeing as I know precisely which key I pressed when it happened (the down arrow)... will that make the diagnosis easier when I take it into repair?
