My monitor goes black and acts like my computer isnt connected at random times but all my fans keep going and I dont get any weird lights and nothing else seems wrong.  Sometimes it happens when I turn it on, sometimes when im playing games, sometimes when I go take a shower, sometimes it wont happen for weeks at a time, sometimes it will keep me from booting for an hour and then not happen for a couple days.  I know its not the monitor because I have two.  When it happens and I press capslock it doesnt light up on my keyboard.  All my parts are about 2.5 years old.


I just dont know if its my motherboard, cpu, video card, psu, ram or hd issue.  I have z77 extreme4(the blue board), water-cooled i5-2500k, amd radeon hd 6850, corsair tx650 psu and multiple hard drives of various types.  Thanks.

I suspect it's the Power Options. Looks to me as if the PC is trying to go into one of the Sleep/Hibernate modes. Set your power options to full ON and see what happens over time.

Unfortunately the PO functionality is part of the MB chipsets, but it's managed by the OS. If the PC maintains this behavior, then you may have to either;

1. Reload the OS, non-destructive first, then destructive reload if that doesn't work.

2. If the OS reload doesn't fix it, then it's a MB replacement.

Good Luck.
