Windows 8.1 computer shuts down unexpectedly.

UPDATE 2... 1. Two days with no problems since pagefile (Virtual Memory) set to 7GB. I'm pretty much convinced that Windows 8.1 has a MEMORY LEAK. In other words, it's bugged. Unbelievably amateur. Loads of people online with same problems. 2. Task Scheduler/Automatic Maintenance is a right pain. Even if you disable it it comes back. This is because the "Maintenance Configurator" resets it, and you don't have permission to change it ON YOUR OWN COMPUTER!! Outrageous. If MS don't change this then I'm going Linux. This and Skydrive (which you're pretty much FORCED to use, is a bloody outrage. 3. Do MS listen to feedback? I've been telling everyone Win 8.1 is your best OS yet. Well not any more. You are creating more bad feeling towards MS. The memory/shutdown issue is amateur, the Scheduler and Skydrive are ourageous, and the Maintenance stuff is a memory-hogging pig. Then "superfetch" grinds your disc constantly, too. What an absolute joke. Please fix these issues. It's not the users' PC's... It's MS rubbish. The answer? Set your page file to massive. And let MS own your PC.

PROBLEM STILL PERSISTS. NOTHING WORKS.

I have tried every troubleshooter offered by MS, and every suggestion.  I've adjusted power plans, hybrid states, fast start-up, and every little thing I can think of.  I'm no newbie.  I know PCs.  I've checked ALL the hardware.  Nothing is faulty.  Just suddenly started happening after upgrade from 8.0 to 8.1.  My PC is a lottery of usability.  It's totally uncacceptable, MS!  You've totally borked something up.  It may not show up on your uber new test PCs but there's lots of people with this problem.  Please help.  And NO, Event Viewer is USELESS and filled with errors (and they're all the same as the other people's - so WHAT ARE THE CHANCES????)

PLEASE HELP.  Or PLEASE FIX IT!!!!

As consumers of technology we have the ultimate say.  I'm done trying to get MS to resolve the issue.  I made the leap of faith into Google Chromebooks, Android hybrids and Linux. 

After having used these devices, I am only mad at myself for putting up with MS' consistent failure to produce an operating system worth using.

As for my computer that runs Win 8.1...I will be reformatting it to Win 7 Pro.  I see an imminent demise to a company that has done an exceedingly good job at annoying customers.

I am having the same issue with my computer randomly suddenly turning off with NO Warning after upgrading to Windows 8.1.

I was just looking at my Event LOGS and see an Error Event about the time this just happened. it has something to do with Windows Live Communication Application Failure. I believe that is the source of the issue.

Here is the Error...

The program LiveComm.exe version 17.5.9600.20461 stopped interacting with Windows and was closed. To see if more information about the problem is available, check the problem history in the Action Center control panel.

Microsoft, what are you doing to address this issue? Secondly, what type of a QA Organization do you have that these issue are passing QA Testing and becoming Production Issues?

Hi,

Page file is what helps keep your computer stable. Although you may think there is enough memory in your computer to handle all the programs it runs, Windows or programs that run on it can exceed that limit, which causes program errors and even system crashes. So increasing the page file might have resolved the issue.
