Then they can't wake. My two Z97A fails recently. Or maybe no mystery, they are just old? First one fine 4 years. Replacement a refurbished, OK just over a month.
Witness says: System sleeping. On wake a pulsation thing where cpu fan, psu fan, & fan on psu, start to spin, then stop, then restart; repeating cycle. No post. Fans on mobo headers don't spin. No OC, no visible issues on board.
Over years I read lots about boot fails, not this. Abort start, no post, repeat. Maybe you'll say it's no different. Old mobos fail lots of ways, it's not unusual 2 fail like this?
One more thing: OS W7-64. I add cuz mobo gets order to sleep from OS. I don't know what goes on between them, or whether it involves BIOS. Doesn't matter as I can't access.
Do you have any questions Lieutenant?
