I have windows 10 I've done memory test, error checking, all hardware functioning fine have not added anything, or downloaded, updates are current, but for the past two days I'll shut down or put the PC in sleep it will say shutting down screen turns off, however fans, the hd and the network stay active for about 2 min then turn off I haven't seen anything in event viewer that stands out, I've tried safe mode same effect, starts right ups though and works amazing just won't turn off with out hanging
