I have a situation which has crept in over the last week on my windows 8.1 computer. Throughout the day, maybe twice a day, randomly and without warning, the computer will shut down and restart. No freezing, no screen lock, it just turns off and then restarts. Could I please have some advice on what to do to try and find out precisely why this is happening and where the issue is. Here is the entry on Windows viewer, it says what has happened but not what the cause is. Thanks.
