Windows 8.1 computer shuts down unexpectedly.

You still having issues?

im just here to add another reply to this so MS can see a lot of people are having this problem. i spent a lot of money on a new computer for work. and i got 8.1 and now i lose all my work unexpectedly and randomly. you can only save so may times a minute.

please help us.

I have to say also that I installed a nvidia GPU card and the problem still appeared at about 2 o'clock. So, my hypothesis of faulty Intel onboard GPU drivers is disproved.

Dear Peyia,

I have 4 machines with windows 8.1 and the problem appears in only one of them.

The problem is the shutdown occurs the same time everyday (at midday, at around 2pm) suddenly, without leaving dumps or log entries. The log entries are just mentioning an abnormal shutdown and reboot and nothing else. That's why I believe it's caused by something close to the system's core (kernel).

I am not a windows 8.1 hater, I believe this version is the best windows of all and I am a very sutisfied windows developer. But the problem is buffling.

I want to believe the shutdown is caused by some hardware problem, but I cannot explain why it is happening at the same time each day...

In reply to Luxus.

Hi Luxus, if you have gone the same upgrade path that Art has done above and you are certain that your hardware is working as it should, then I can only suggest that your problem is a driver that is not compatible with Windows 8.1.

You will need to check your dump file or log file to see what error message was given when it shutdown, to try and locate the piece of hardware, or run one of these Driver update programs and check that all the drivers listed are windows 8.1 compatible.

I still stand by Microsoft that windows8.1 works satisfactorily, after all it is only a few machines which are causing a problem, if you purchase a new one from  eg PCworld or wherever it all works fine, so it cannot be the OS.       Also make sure your motherboard is capable of running 64bit system if you upgraded to the 64bit Windows 8.1, as many XP machines and the first issues of Windows 8 were 32bit systems.

Please also read the first paragraph of the link given in my last message on 18th August, you cannot upgrade, you must do a clean install, and have the correct drivers for your motherboard, etc.
