So lately I just noticed that after I left my PC and had a bunch of stuff open like web pages and a pdf file.. I left and came back and saw it was turned off. I tried the power button and it wouldn't turn on.. When I turned it back on though the same stuff was opened still.. so weird ?The only way to get it to turn back on is to press the button at the back of the PC Case and switch it on and off, i just switched the plug from the extender and put it directly into the wall..
Does anyone know why this is happening?

this is my build..

Well my brother noticed it and then told me about a week ago.. I just left the computer today and noticed it.. i was just on some web pages and a pdf document open. This is a newer PC Build so im not sure why it is happening.
