Today, same like yesterday, my laptop rebooted instantly while I was browsing (Chrome), editing a txt file in Notepad and had mIRC open. I looked in the system event viewer and was able to find a message that says: Code: The previous system shutdown at 14:48:25 on 3-1-2014 was unexpected. I am not sure how the other messages in the event viewer relate to this improper shutdown, or how to troubleshoot the problem. But I could post them here if I know how I can do that in a neat fashion... Please help me find the reason for my PC rebooting so unexpectedly.
