I have a strange problem. My computer is Windows8.1. Recently, the computer starts to power off immediately during the start-up when windows 8.1 logo shows up it powers off. But the strange part of this problem, it does this one time only. I turn-on the computer in the morning and powers of immediately like electric city is gone when windows 8.1 logo appears. However, i do start it again and this time it works without any problem. This problem is happening everyday for at least 15 days now and i couldnt find any log record about it in the events. Any idea where to look what to do ?
