I am using windows 8 suddenly my computer started restarting no error and no messages

steps taken:

checked for viruses, memory test,windows diagnostic tools,etc found nothing

Finally Changed My Operating System to Windows 7 Ultimate Even Then Computer Keeps Restarting but works fine safe mode

I have given my motherboard in servicing center and got it today got display and the computer keep restarting but works fine safe mode

Open the Tools->Event Viewer. It records these things with some detail.

I've found Windows 8.1 to be the most stable Windows OS so far. As you surmise a hardware issue is the most likely one

Try swapping out your power supply. To see if maybe this is the cause.
